IN an effort to lose weight off the race car, I want to cut the SFCs off. However, I use them to jack up the car.

After seeing several "pro" teams use a receiver/stab setup off the roll cage, I began fabricating this kind of rig.

I used 1" square tubing as the receiver and gusseted the hell out of it to keep deflection to a minimum. I have some 3/4" solid bar stock I was using as the stab.

After welding the receiver portion to the cage and mocking up the stab with plenty of gussets, I tested the rig and ... it bent. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/mad.gif) 3/4" solid bar stock bent like a pretzel.

And it yielded right at the end of the gusseting. Think of it as a pry bar.

I opened the door and placed the jack on the end of the receiver and lifted the car without an issue ...

So help me out here ... what can I do to the bar stock I have to increase it's strength or what kind of 3/4" bar stock can I source that will lift 1500lbs?

Not THAT much heavier. Granted it is much thicker wall than the thin wall tubing you are working with but the 6-7" of it is no big deal.

It is not the same size as the hitch on your 2500 truck.....it is the itty bitty reciever and hitch....1 1/4" square I think.

I don't mean to pick on you Randy but I've been thinking about this a lot as I am trimming out a wire at a time out of my wiring harnesses. There are probably hundreds to even a thousand little things that you touch on the car over the years. If you scrutinize every 0.1, 0.2, .5, 1lb, it adds up. Not right away, but over the years each little detail x100 or x1000 gives you some significant savings. This isn’t something that hasn’t been said before, but I just thought I’d say it again.
