Guys,
I lifted my truck 6 inches using no blocks. I used springs from an ext cab S10. And a full size Bronco.
I took the biggest spring from the rear of the S10 and added them to the front of my K10 and took the Biggest out of the rear of the bronco and added to the rear. Worked perfect. Level truck..... Of course I tried many Different springs til I got it right. But this worked perfect. I ordered shock mounts and weled them front and rear. Worked perfect. The steering arm is a pain and I always will suggest spraying JB Blaster and then cooking it. Makeing the blaster boil in the cracks really works.
