But you can do some work to you stock setup and make it work awesome. Check out the Hotchkis setup for some ideas.

I do have a minor in Mechanical Engineering, does that count or matter? Here is quality information on the AlterK setup. I wouldn't touch one with a 10 ft pole on anything but a drag racer. Even says so right in the instruction sheet for the RMS setup. https://board.moparts.org/ubbthreads/show...e=0&fpart=1 Enjoy, I'm out! Ryan Last edited by Devil; 07/13/12 02:19 PM.

K member, control arms, spindles, discs, torsion bars,sway bar, tie rods, etc etc Complete, ready to bolt in. Why? Because the dude I bought it off of converted his to R&P and drives it daily.

PS, your thoughts would be much safer over in the drag race forum. "When one’s appeal is emotional, it does not matter if there is no substance."

If you choose not to go the Alter K route, a Firm Feel box, gusseted K and suspension re-build with good parts will tighten things up consideraby. Big improvement.

Most of the the kits are designed for drag racing, but there are a couple that are aimed more towards the GT crowd. They are all fairly expensive ($3000 or so). You didn't say what you were trying to accomplish so it is hard to help much. If you just want to make the steering a little better then get your box rebuilt by the guys at Firm Feel. There is a ton of stuff that can be done to tighten up the stock steering system. 11/16 tie rod ends, bracing the K-frame around the steering box, etc. I covered this topic in my B-body book so maybe start there. There is also information in the old Mopar Chassis book as well as various out of print Mopar suspension books.

I have question about the above setup, how heavy is it compared to stock? It looks heavy and would be more geared to auto cross racing more so than drag racing? To the OP I'd recomend FF upper control arms along with one of there boxes and I sure you would be happy. The postive caster that you get with the upper control arms is great, I mean huge.
