I've put together an upgrade package for the 3rd/4th gen Fbods - 3rd gens especially will break axles under the stress of RR duty, and I've cracked a 4thgen axle. Dragstrip use with slicks will break them, too.

These axles are direct replacement, use OEM wheel bearing and seals (not included) and fit any of the popular diffs (also not included).

Package includes:
1 Pair Yukon Replacement Series axles for 93-02 4th gen non TC cars or TCS cars
10 ARP 100-7708 2.5" long wheel studs, pressed in place
10 Dorman short, open bulge lugnuts with 19mm (same as 3/4") hex

Cost is (call, prices vary with application) plus shipping plus CA sales tax on orders shipped to CA address.

for the front, extra set of 10 ARP studs $32
for the front, extra set of 10 Dorman lugnuts $16

Extra long 3.25" ARP 100-7713 studs are available, set of 10 $72

questions/comments PM me or email me at ablaine (at) cruzio (dot) com or call me at 831 427-3296 evenings PST

edit: Superior raised prices by $10 per axle, so I had to raise the package price from $185 to $205
edit: another price increase, to $215 for the package
edit: added pics of my cracked OEM axle - I found this after a rather spirited session at Sears Point. Glad it didn't let go there! The crack goes all the way around and thru the hub flange, and has started to twist off.
edit: the yearly price increase happened: new price for the package is $231 + changed to Dorman nuts
edit: price increase to $350
edit: price drop to $295
edit: revise pricing on ARP/Dorman
edit: change to Yukon, revise pricing

Alan,

Axles are on my list of TO DO's this winter. I was planning on doing the C-clip eliminator route that Al (CMC#5) did on his car earlier this year. Any likelihood you can come up with a kit to do something along those lines?

Posted by: 94bird Oct 18 2006, 03:00 AM

I'm also interested in a new set of axles this winter and would like to do the C-clip eliminator too.

Getting my driveshaft now, and then plan to do the T2R and axles all at once.

Dammit alan ... yer killing me here.

Are the studs the factory stud thread and pitch?

Posted by: Blainefab Oct 18 2006, 07:06 PM

Mitch - Yes, the installed ARP studs (100-7708) are factory thread and pitch, but 2.5" long. Lugnuts are interchangeable with the fronts.

For another $14 I can include 10 more lugnuts for the front, and for another $28 can include 10 more ARP studs for the front.

For those that buy the axle upgrade and extra studs/nuts for the front hubs - ship me your front hubs and I'll press the studs in (straight ;-) ) for no extra labor charge, just return shipping.

If you're local and walk in the door with hubs/axles (off the car, of course) and buy the ARP studs and Gorilla nuts I'll press them in N/C.



On the full floater deal, I'm looking into it, but Al's estimate of $600 in parts for the whole setup looks pretty spot on, and the failures I've seen on RR cars have been of the shaft or hub outboard of the wheel bearing, not the spline end or Cclip flange. The reduction of end play on the full floater is what you would get for the big difference in cost vs just an axle upgrade.

Posted by: mitchntx Oct 18 2006, 07:08 PM

Did that actually stop his pad knock back issue? I know I had it BAD in my old '98

What's the final Paypal price on those axles with studs and lugs. I already have a couple packages of those same studs on the shelf.

PM or e-mail me.

Posted by: rmackintosh Oct 18 2006, 08:24 PM

I am pretty sure he said it did......

Posted by: NataSS Inc Oct 20 2006, 06:16 PM

If the full floater comes to fruition, I would be on it.

I'm interested - 1999 Z28

Rear axles/studs/lugnuts
Front studs/lugnuts
Extra lugnuts

I'll have to verify the stud length - I need the long ones.

Thanks

Posted by: nape Nov 9 2006, 02:54 AM

Alan knows the number, but for an FYI, the long (but not super long) ARP studs are 7708s. Alan talked me out of the 7713 (super long) studs and I'm glad. The 7708s stick out of the factory lug nuts even with a spacer.

Posted by: Blainefab Nov 9 2006, 12:12 PM

Mike - The LS1 axles are showing 2wks ARO for delivery to me, and another couple of days for me to get them down to you after pressing the studs in. I have the 2.5" long ARP studs and Gorilla nuts in stock.

Here's the cost breakdown:

Axle package (2 Superior axles, 10 ARP studs, 10 Gorilla lugnuts) $185
set of 10 ARP studs $27
set of 10 Gorilla lugnuts $13
extra set of 20 Gorilla lugnuts $26

subtotal $251

Ca sales tax $20.08

Yes - The ARP studs I stock and install in the axle package are the 7708's - they are 2.5" long which is plenty for any spacer less than 5/8" thick. Here's a pic of the 2.5" long studs with a 1/4" spacer on a GS wheel: There is .330" sticking out past the nut.





The ARP 7713 are 3.25" long - If the extra 3/4" is needed, I can get them, and press into the axles instead of the 7708's. They are about 2wks ARO, and are a lot more expensive. Your price is $30 per set of 5. Yes, almost twice as much as the 2.5" length.

Posted by: Blainefab Nov 9 2006, 12:38 PM

Here's the axle upgrade package, these are 3rd gen:

Posted by: Glenn98ZM6 Nov 9 2006, 09:42 PM

difference between the 93-96 and 98-02 is the center hub that fits into the wheel, correct? so if i ordered the 98-02's to work w/ my 95, i could more easily use the 98-02 wheels, right?

Posted by: Blainefab Nov 9 2006, 10:36 PM

Yes, wheel hub OD is smaller on the LS1 axles (Are the wheel hubs on the LS1 wheels smaller? I'm accustomed to opening up the ID of the C4 Corvette wheels to fit the LT1 axle hub but don't know if this is the case for a LS1 Fbod wheel onto LT1 axle).

Axle length is same, and splines are the same. I have the Superior LT1 axles in house, they do have the flange for the TCS reluctor option. I'll call Superior and ask if there are any other differences besides the wheel hub OD.

Posted by: Glenn98ZM6 Nov 10 2006, 02:22 AM

yes, 98 and up f-body wheels have to be opened up to be put on an 93-97 F-body. it seems to only be true for the rear though. never seen it needed for the front.

Posted by: Blainefab Nov 10 2006, 09:54 PM

Well now I'm confused - I called Superior and the guy said that the LS1 axles were 1/2" longer than LT1 (and the published specs were incorrect) but I don't believe that is true - LS1 folks would be having extreme outer fender well issues if the cars had an inch wider track than the LT1 cars. I'll measure Mike P's when they get in, will be 7-10 days.

Here is a Superior LT1 axle next to an OEM. The TCS reluctor flange puts more meat right where one of my OEM axles cracked.

Posted by: mitchntx Nov 13 2006, 01:09 PM

Alan ...

I would prefer the axles for a 98+ car in order to aleviate the wheel fitment issue. Is it too late to make that change?

Posted by: Blainefab Nov 13 2006, 02:37 PM

Mitch - Nope, not quite too late - I'm placing the order later today, along with Mike's. I'll make yours the LS1 version.

Posted by: CJ-TA Nov 19 2006, 05:02 AM

Can I buy just the axles? I already have studs and a crap load of nuts..

to 78550?

Posted by: JaredT Nov 29 2006, 08:55 PM

Alan,

what was the answer on the LS1 vs LT1 axle length?

I need to put my name on the list, I've got an LT1 and shipping would be to 50219.

If the LS1 axles really are 1/2" wider it wouldn't hurt my feelings when running the Z06 rears, I could go without spacers, but not sure I would like what that would do when running the WS6 wheels with stickies.

Posted by: Blainefab Nov 30 2006, 05:57 AM

Jared - The LS1 axles arrived yesterday, and they are the same length as the LT1, as I expected. So the only difference LT1 vs LS1 is the slightly larger OD of the hub on the LT1 part. If your Z06 wheels have already been clearanced to fit the LT1 axle hub then there would be no advantage in the LS1 axles. Your choice - price is the same.

(Mitch paid less shipping 'cause I used the shipping weight of the 3rd gen axles to me to base my quote on - turns out, after adding the 1.7" longer 4th gen axles, and the studs and nuts that the UPS bill is a little higher. SO if you buy the package, Mitch owes you a beer, on me ;-) )

This is the only reference I've seen re custom Cclips: http://corner-carvers.com/forums/showpost.php?p=454115&postcount=5

Superior raised their prices by $10 per axle, so I updated the opening post of this thead. Superior/ARP/Gorilla package price is now $205 plus tax and shipping.

Posted by: Powerslide91 Jun 1 2007, 06:48 PM

Alan,

For a 3rd gen fitment, do you happen to know the weight for the Superior axle?

Jeff

Posted by: Blainefab Jun 1 2007, 07:54 PM

3rd gens are approx 36#/pr

Posted by: SStrokerAce Jun 2 2007, 06:09 AM

Alan,

Correct me here but I thought the difference was 26 and 28 spline axels for the LT vs LS cars.

I'm going to be getting some here soon, do you have the EVO axels from them as well or they still working on them for LS cars?

Bret

Posted by: Blainefab Jun 2 2007, 09:45 AM

Nope - LT1 and LS1 axles have the same spline count: 28. Other than a slightly larger wheel hub OD on the LT1 axles, they are interchangeable.

The EVO series axles are also 28spline, and the same alloy as replacement series. The only differences I see from Superior's ad copy is that the EVO series are packaged in a kit with bearings and SAE studs.

For most of the folks here, the OEM dia, 12mm x 2.5" long ARP studs are fine, and bearings can be sourced locally if needed

My supplier lists the EVO kit only for the LT1, which would fit in a LS1 axle but the LS1 wheels would need to be opened up.

or,

I can drill out LS1 replacement series axles and press in SAE ARP studs. Let me know if you'd like a quote.

Here is Superior's description of the Replacement vs EVO series:

REPLACEMENT SERIES

These High Quality replacement axle shafts feature the same Superior alloy used in our Evolution Series axle kits, along with computer controlled induction heat treating resulting in a stronger, more durable axle shaft. All our shafts use a cold-formed rolled spline process that produces an axle spline up to 35% stronger than cut splines! These are direct replacement axle shafts. No modifications needed.

For extreme duty applications, front axles, or complete kits with bearings, studs etc., check out our Evolution Series kits.

EVOLUTION SERIES

These kits are designed and engineered in-house to be the best axles on the market! We've listened to our customers, and improved on the factory designs. Each axle or axle kit solves a specific problem for your customer, and are packaged installation ready with studs, bearings and seals. Many feature larger splines for extreme duty applications, and dual bolt patterns for upgrading to larger studs.

90+ 3rd gens with the 10 bolt got 28 spline axles, and all 4th gens got 28 spline axles. The only cars with 26 splines were the early 3rd gens with the 10 bolt.

Posted by: sgarnett Jun 2 2007, 02:33 PM

Alan, do you have a C-clip and/or replacement axle handy that you could measure? I should receive an 8.5 oversize (slightly thicker) C-clip assortment kit in a few days for comparison. At this point, I think the clips were made for an 8.5 10 bolt. I'm not too optimistic that they'll fit a 7.5 axle(Stan's probably right), but it would sure be handy if they turn out to be interchangeable.

And on that topic, are the Superior axles set up with any less play than stock? In other words, did they cut the slots any farther outboard than stock?

Posted by: SStrokerAce Jun 2 2007, 06:04 PM

Alan,

Thanks for that. Looks like your kit will be fine for me. I'll source a axel housing a pick up a T2R here in the future and give you a ring for axels and studs.

Bret

Posted by: Blainefab Jun 2 2007, 08:36 PM

Sean - I have a couple of OEM takeoff axles in the shop, I'll measure the grooves tonite. No Superior in stock, but I believe they are sized no differently than OEM. I installed a set at the shop and had to space the caliper brackets out .030" to get the PAB off the rotors.

Brett - Great! I keep the studs/nuts in stock, but not the axles - sometimes it takes a few weeks to get them in so get them ordered ahead of time.

Posted by: JaredT Jun 15 2007, 02:48 AM

Cool, this deal is still going on. Think I'm finally ready to order some axles. Can you recalculate price to 50219?

Superior raised their prices again, but I do have one pair of LS1 (fits LT1 cars too) axles in stock at the old price of $205 for the package, plus shipping. After this set sells the price goes up to $215 for the package.

Might be nice to have a set in the trailer at MidOhio ;-)

Posted by: supermac Aug 18 2007, 05:13 PM

Alan,

And anyone else who might have experience with this. What is the failure possilbility on the stock axles? This is the only thing on my car I didn't replace on my car when I built it, basically is this a luxury item or a must have? I am getting some other stuff from Alan, maybe I should get these as well.

Posted by: Blainefab Aug 18 2007, 08:07 PM

Statistically by failures per mile driven, the probability is quite low, but given that we are on the high applied stress part of the curve, and the potential for a lot of collateral damage from axle failure and the resulting loss of control, it is a good item to replace periodically. Some failures have been right across the shaft at the wheel bearing seal, and others at the hub flange.

I've cracked a 4th gen axle, I'll take a pic tonite. I pulled it out mid season to do a diff upgrade and found the crack.

I've seen three 3rd gen axle failures on CMC cars: Julie Bergman, Dave Morin, and Nick Littleton. Dimensionally, the 3rd gen axles are no different than the 4th gen in the area of the failures, so it might be I've seen more 3rd gen failures because of the lighter weight of the cars, or age and time in high stress service.

Posted by: Blainefab Aug 19 2007, 08:36 AM

I added some pics of my cracked 4th gen axle to the opening post of this thread: http://www.frrax.com/rrforum/index.php?s=&showtopic=8546&view=findpost&p=90131

Posted by: Blainefab Aug 1 2008, 09:36 AM

Superior raised prices again, and I just got cleaned out of my stock at the old price. New orders placed after 7/31/08 will be at $231, with ARP studs and Dorman nuts.

Posted by: Blainefab Sep 14 2008, 11:06 AM

For those waiting for axles, my shipment from Superior arrived, so prior orders will be shipping Monday.

My disti has stock again, also, so if you've been waiting to order, go ahead and PM me with your shipping ZIP code.

FYI, I've been backordered since March. If you were thinking about upgrading, I'd order them now, no telling how long this stock will last.

I have plenty of stock on the ARP studs (both 2.5" and 3.25" lengths) and Dorman lugnuts.

Posted by: Blainefab Sep 19 2008, 10:44 PM

Well, I spoke too soon - only one of my backordered pairs of axles were shipped. BUT, the good news is that my disti is accepting new orders again, so I just ordered 10 LS1 axles. They are claiming 9/26 ship date but I'm not going to hold my breath, nor take payments, till I see a tracking number.

For those folks that have been waiting, hopefully won't be much longer.

Posted by: sawedoff Sep 20 2008, 01:01 AM

I'm kinda' interested but I'd need way better bearings if it's at all possible.

Posted by: Blainefab Sep 20 2008, 09:10 AM

I could supply wheel bearings and seals, but probably would have to charge a little more than you could get them for at your local auto parts supply. Should cost under $30 for a pair of each.

Timken 8660S seal
Timken 5707 bearing

I have the bearing/seals in stock, let me know if you want me to include them, and what your ZIP code is for a quote.

We already spoke, but just incase... put me down for a set Alan.

Posted by: Blainefab Dec 19 2008, 09:46 PM

OK, Superior says 1st week of Jan for my shipment of 12 LS1axles. I'm still not going to hold my breath or ask for payment yet, but if you need an axle package please watch this thread and be ready to PayPal me when I post a shipment confirmation. 6 axle packages will be available at the current price.

These will be LS1 axles - they fit LT1 and LS1 cars, both 3ch and 4ch ABS systems, with or without TCS. Package price with 2 axles, 10 ARP studs pressed in straight, and 10 Dorman lugnuts will stay at $231 + shipping for 6 package sets. After these 6 the package price is going up to $265.

Posted by: Blainefab Jan 12 2009, 08:59 AM

Superior pushed delivery out to 2nd week of Feb. Good thing I wasn't holding my breath.

Posted by: Blainefab Feb 3 2009, 11:46 PM

Finally the situation with Superior has been resolved - some good news, some bad news.

3rd gen 10bolt: Axle package is available, delivery approx 2weeks ARO, price is still $231 + UPS shipping and CA sales tax if shipped to CA address. Prices on other axles have been increasing dramatically , so if you think you want to upgrade this season I advise doing it soon. Package still includes 2 Superior axles, 10 ARP 2.5" long studs pressed in place, and 10 Dorman lug nuts. OEM thread size and pitch. Bearings/seals/longer studs, etc also available.

4th gen LT1 10bolt: Axle package is available, delivery approx 2weeks ARO, price has increased to $350 + UPS shipping and CA sales tax if shipped to CA address. Package still includes 2 Superior axles, 10 ARP 2.5" long studs pressed in place, and 10 Dorman lug nuts. OEM thread size and pitch. Bearings/seals/longer studs, etc also available.

4th gen LS1 10bolt: Superior has discontinued this axle. The LT1 axles will fit the LS1 cars by opening up the ID of OEM LS1 or Ybody wheels slightly with a drum sander. All LT1 wheels and most aftermarket wheels will fit without modification.

ARP studs, nuts for front, and hub centric wheel spacers are in stock and available.

Posted by: 00 SS Feb 6 2009, 04:48 PM

I'm surprised they discontinued the LS1 version and not the LT1 version since the LS1 would have worked in all 4th cars without modifications. I think they goofed.

Posted by: Blainefab Feb 6 2009, 11:02 PM

I agree - BUT, I've seen other mfr axles in a LT1 housing with the smaller LS1 hub dims. I get a Superior shipment in next week - if they discontinued the lowest wholesale cost part number, and then "updated" the LT1 hub dims to be universal, it would have been a sneaky way to do a 50% price hike.

Posted by: Blainefab Apr 2 2009, 11:23 PM

OK, I got my shipment of Superior axles in and have been mulling over the changes they made to them. Good news is that they did reduce the diameter of the hub to match the LS1 dimension, so these will fit LT1 or LS1 or Corvette wheels without modification.

They did away with the reluctor flange, so will not work on a TCS car with ABS/TCS functional.

The change that had me concerned is that they made the stepdown from major to minor diameter near the hub end instead of at the spline end, so for about 20" of the shaft length, the diameter is 1.245" vs 1.340" dia for OEM or old Superior axles.

An engineer I trust feels that the midspan of the shaft is not the most highly stressed area, and Superior says they have had no issues with them, so I'm going to let my customers decide if they want to purchase or not.

Alloy is still 1541, journal dia is the same, spline dia is the same, splines are still rolled. Stud mounting flange is slightly thicker than old Superior or OEM.

These axle are 1# lighter than OEM, and 2# lighter than the old Superior.

Posted by: TSHACK Apr 3 2009, 02:17 AM

Alan It also looks like the radius between the axle shaft dia & the hub taper/step is larger. which would be a good thing. Or I'm i seeing things again.

Posted by: Blainefab Nov 26 2009, 12:18 AM

Surprise! Superior has re-activated the LS1 axle part number. I ordered some 6 weeks ago, not really expecting them to ship, but they showed up yesterday!

They are LS1 hub size, so fit all wheels, Fbod and Y bod. See above post, for pic - far left axle.
They have the larger dia shaft, so are the same weight or heavier than OEM.

They have the ABS reluctor flange, so will work in both TCS and non-TCS cars.

My cost has come down a bit, so I'm lowering the package price to $295
Package still includes 2 Superior axles, 10 ARP 2.5" long studs pressed in place, and 10 Dorman lug nuts. OEM thread size and pitch.

Bearings/seals/longer studs, etc also available. ARP 2.5" and 3.25" GM knurl, and 1/2" screw-in in stock. Dorman lugnuts in stock.

2 sets in stock, for shipment Monday.

More available, disti is showing 2 weeks, but probably longer. Price subject to change on orders beyond these 2 sets.

Reviving an old thread here, Alan, what do you currently offer for a third gen axle package. I'll be using an Auburn Racers diff so I'll need 28 spline. Thanks

Posted by: Blainefab May 7 2012, 08:49 AM

I'll check pricing on that - so it's a 10 bolt, I believe late (90-92?) 3rd gen? Not a Dana, and not a 9bolt, right?

Posted by: rlewi771 May 7 2012, 04:28 PM

Exactly, a 10 bolt. The later ones (I think you're about right on the year range) got the 28 spline so I think there would be an offering for the third gen length with the 28 spline. Mine currently is a 26 spline, but the Racers diff only takes 28 spline, so it will be a good upgrade anyways. Thank you.

My rear end was originally a drum brake rear. I have used drum to disc conversion plates from flynbyeperformance, will this matter? Was there a difference in axle shafts between a drum and a disc rear?

Posted by: Blainefab May 9 2012, 08:10 AM

My disti says they have no separate part number for the drum brake axle, and they have an app note that says 'disc brake axle works on drum brake'. The only difference may be OD of the hub will be different in order to index on a drum vs a disc.

Does the flynbye conversion change the hub dimension, or just adapt the backing plates to the caliper abutments?

I've got a question, Alan. I got those 1/2" spacers you sent me last week and I'm wondering if the 2.5" ARP studs are adequate. I wish I had a pic. The stud goes all the way through the nut with about ~1/16" or maybe 2 threads showing. To me that looks like about 1" of thread engagement.... Is that enough or do I need to get the longer ARP studs? I figure it is but I thought I'd ask.

Jeff - You are good - If there is any of the threaded portion of the stud sticking out past the nut then you have plenty of thread engagement. The ARP's are threaded all the way to the end, so easy to verify proper engagement visually. For other studs, OEM and Moroso, for example, with the bullet shaped starter nose, you have to count the number of turns of the nut to verify proper engagement.

The OEM nuts only have about 1/2 of their length threaded, I recommend replacing them at least once per season. The Dorman lugnuts that I stock are fully threaded, providing a little extra security, but I still life them out yearly.

FWIW a related topic that I just resolved with another customer - the ARP studs are not useable with closed end lug nuts - they are long enough that the nut will bottom on the stud before properly loading the wheel.

It only adapts backing plates to caliper abutments. Come to think of it, I cant really recall how the fitment of the rotor is over the axle, nothing has ever struck me as incorrect about it. Either way, sounds like those axles will do the trick. Thank you for your time checking it out, when I have the funds together i'll give you a shout.

Alan, looks like I need a set of these for my LT1 CMC car. I'll send you a PM.

Glenn - I emailed you an estimate, will get firm pricing and leadtime Monday.

One thing I forgot to mention is that if you want to use spacers thicker than 5/8" you'll need the longer 3.25" ARP studs - I can put together the package with those instead of the 2.5" ARP's for +$40.

The CMC and AI track width allowances changed, for 2012 I think, and I've sold quite a few 3/4" and 1" spacers since.

Posted by: GlennCMC70 Mar 30 2013, 02:06 PM

Half inch spacers is plenty. Track for 4th gens went down to 74.

Glenn - The package price from last year is still good on these, and my disti has local stock. UPS gnd shipping to TX is $38:

I looked at using the TC spec axles, they have the ABS tone ring boss right where yours cracked, my SWAG is that the extra steel might prevent the cracking - but they are about 1/4" shorter than the non-TC axles, so won't work in a non-TC housing.

1 Pair Yukon Replacement Series 1541H steel axles for 93-97 4th gen non TC cars
10 ARP 100-7708 2.5" long wheel studs, pressed in place
10 Dorman short, open bulge lugnuts with 19mm (same as 3/4") hex

Cost is $435, plus shipping plus CA sales tax on orders shipped to CA address.
