Default Goodbye leaf springs!!

I already posted this in my build thread but thought I'd share it in the suspension section as well.

This was Designed and built by Stoichiometric and the welding work was done by WildeRacing. They know the what's and why's better than I do but all I know is it 30,000 times better than my old leaf spring set-up.

These are the best pictures I have of it from far away, consists of two "Truck arms/bars" that triangulate as far forward and as far up as possible to a cross-member that was fabbed up behind the cab. Also a Pan-hard bar that is welded to the drivers side frame rail and the passenger side axle tube. And adjustable Fox Coil-over shocks.

Here's a couple shots of the travel of the rear end, in all these pictures the compressed wheel has another 2-3 inches of travel until it touches the fender:

Looks good man. I do have 1 question though. Why did they opt to weld the spring tabs to the bars and not on plates that drop of the rear axle?

looks awesome, very well thought out.... but I have one question..... how do you adjust pinion angle? I see the heim/bushings up front but no adjustability out back? did you figure that in and just built the bars to set it and leave it alone? Just one curious question other than that, I will be over to pick it up this weekend, thanks for all your hard work I really appreciate it. If you don't mind just have her filled up and washed before I get there :o

Awesome setup. I wanna do the same thing to my truck. I worried about loosing the abillity to toss my sportbikes and or dirtbikes in the back of my truck, 800-900 pounds. Let me know how it hauls things when you get a chance.

I'm really interested in this setup, I'm building my truck to do road racing courses/autocross and road trip stuff.
