I did something a little different. I had Posses build me a set of springs for the front of my 36 Chevy truck with an additional 2” of arch. I then mounted my axle to the top of the springs. When I got it all together and got weight on my axle I found that I found that I only had 1½” of space between the axle bumper and the frame, bummer. My plan now is to mount air shocks to add a little height.
I have this in my photo journal, but have not mounted the air shocks yet.
