Okay guys how about a little input. I have read carefully virtually all posts concering lifts. After carefully sifting through all the info I ordered a 4" ProComp lift, Rancho 5000 shocks, steering arm, and have the wheels and tires all sitting in the garage waiting for Saturday. I realize instructions weren't meant to be read until you have parts left over and you can't figure out where they go, but I read the Steering Arm instructions. What I found interesting was based upon all the posts, steering arms are a little difficult to remove. PROCOMP - GM 400 Steering Arm Step 4) Remove the three self-locking nuts which hold the steering arm(Some tapping may be necessary to loosen the taper wedge locks which hold the arm to the studs. SOME TAPPING! Do you think they have ever installed one? Can't wait till it's finised.
