MJM Racing is proud to present the first rebuildable, adjustable and regreasable front hub for 4th gen F-bodies. As most of you know already, these have been a long time coming and have gone though several interations and lots of testing over the last two years. If you've ever autocrossed with 315 Hoosier's or Kumho's, you know why these were developed.

Pictures can be seen here:

Highlights:

1. New forged and hardened 4340 steel spindle made by Mark Williams Enterprises to MJM Racing, LLC specifications
2. Timken tapered roller bearings
3. Factory ABS retained
4. Original exterior dimensions retained for a "bolt on" application with no other modifications required.
5. Adjustable for bearing play, regreasable and rebuildable.
6. Comes with new ARP studs

We will begin to take orders on 1-1-09.

We need to get at least 20 pairs in the initial order to get the best pricing on machine work and parts. Please post any questions as well as stating your interest so a list can be compiled.

The initial price will be $650 each plus a core. That price will apply to this first initial offering only and these are only offered to the people of this site at this time. The core charge will be $100 per hub if you do not have any old ones you can send. Frankly, cores are necessary and if that ends up being too low of a core charge to get people to send cores, it will go up. Please be considerate and at least knock the big chunks of rust, dirt and grease off before you send them. If you have already sent cores to help with development your names are recorded and you need not send any additional cores (unless you want to).

Our lawyer has prepared a document that must be signed by each interested party prior to any transaction. A copy will be emailed to all who state they are interested in purchase.

Please post all questions here or call me, my PM folder is already a bit full.

Sean, If you need something, call, we'll work with you. They aren't going away, but the GP type pricing just isn't possible with so few interested.

So I will still be able to get one later, but it will cost more? That's fair.

Do you still need cores? I have a collection for you.

[00 SS]

Available later - Yes
Cost more - Yes
Cores - Yes, please send as many as you like.

[Doug Phillips]

Are these still available? Cost? Are they available for the C4 Corvette?

Doug,

At the moment they are not available. There was a recent failure and, until I know exactly why the part failed, I'm not making any more. I have no interest in selling an inferior part, so I hope you understand. Once the cause is determined I'll post it up and either make corrections or resume selling, it depends on whether the cause was an isolated issue or common issue.

I appreciate you interest and yes the design does apply to the 91+ C4 as well as 4th gen F-bodies. I'm hoping to resolve this quickly but if you're in need of hubs ASAP, I suggest getting another set of stockers for now.

I have a C4 Vette and I am having trouble finding quality front hubs. Apparently SKF no longer makes a part, and just about the only name brand left in the game is Timkin. Am I missing any??

The Timkin part number for 4th gen hubs is 513090, and the C4 hub part number is 513085. Other than the Camaro 4th gen bolt holes being threaded, is there any difference between the actual bearing themselves? The 4th gen hubs are nearly $100 cheaper, however if the bearing will fail faster it is of no value and I will purchase the more expensive C4 hub part #

Can anyone provide insight?

Thanks,

Chris

There is no other difference in the two part numbers. In fact, if you buy the 4th gen PN, all you need to do to install them is insert your existing bolts through from the back. The threads are the same. This is only true for 91+ C4.

As for the quality of the Timkens, I can't say. I used to kill them just as fast as any other brand.

Here is a new solution to this persistent 4th Gen front hub/bearing issues. Check out the newly designed front hub assembly that retains ABS functionality here: Hoosier Performance Engineering's billet 4th Gen hub
