    As the post says, I was wondering if you can run a 2nd gen lift on a 1st gen truck. I read through some old posts and read that our spring hangers are 3" shorter. Is this true, and if so, can I just relocate them to accept 3" longer front springs? Are the rears OK?
    Thanks,

    you can move em for the front but its a pain. 1 1/2 both directions keepes it all centered. the back ones are all 52" iirc. unles its a one ton then theyu are 56" you should be able to find some used ones pretty cheap around here just use the right ones.

    I jsut bought a welder and got my TC EZ-rides (73-up 4" version) shipped to my door from ORD. After welding up the crack in my frame and reinforcing it some I am going to move the front spring hanger forward 1.8" (the spacing between the rivits that attach it to the body mount). For the rear I am just going to make a longer shackle (haven't desided how much longer yet...). I'll try and post some pics when it is done.

    No you can not run a 2nd gen kit on a 1st gen...YES 1st gen's have have shorter springs 3"....YES you can relocated them, but why both OEM and aftermarket stuff is available...also the rears are OK 52" and if you want to buy new shackles for the rear GM sells them with bushing already in the but if you want Poly bushing there 1 3/8....energy supension sells 1 3/8 bushing for the rear.. /forums/images/graemlins/k5.gif

    You can just remove the rivets holding the front hanger on, notch it to fit farther forward on the frame, and re-attach it with the 2 rear holes lined up where the front ones were, drill 1 hole in the frame for the front mount hole, and make a bracket coming off the frame for the outer bolt if you want too. I never made it around to that and with 3 bolts my suburban has been launched in the sand quite a few times with no issues. It will move the axle forward but its not that noticeable and it gives you more clearance form the back of the fender when the shackle compresses.

    Yep, thats exactly what I said -your 4" lift kit came with 6" rear springs because the advertised lift is for 73-91 pickups.
