[broncoman6524]

MY buddys got a rolled k5 that im thinking about pulling the lift nad tires off of for my truck. Its an 88-91 k5. i was looking on roughcountrys web site to figure out just how much lift it has and it says that the 88-91 is diff than the 77-87 use diff lifts? is it true? ive got an 84 what would it take to make this lift work?

Lift will be 73-87 for trucks but 73-91 for blazers, suburbans and crew cabs.

only problem you may run into is the difference in spring eye size for the rear eye on the front springs. I believe they were 7/16" in the pre 87s and the 87-91s were 9/16.

You are correct, but that is easily fixed.

 

[broncoman6524]

would that be fixed by like drilling a 9/16 hole in the spring hangers? bc that wouldnt be that hard or would it comprimise the strenght?

You would drill the shackles to 9/16" and use a 9/16" bolt instead of the 7/16" bolt.

or you could just buy new bushings that are correct for your truck, they should fit right into the springs.

I took the lift on my 87 off of a 76. Bolted up just fine. But little did I know, the springs and shocks were trash. Now I'm in the market for 4 new 4" lift springs, but can't afford brand new ones.
