Gmt-400 Suspension ?'s

[newdude]

Friend of mine has a 1995 Chevy K1500 ext cab, 4x4. So far, he has cranked his bars all the way, and added blocks in the rear. He is looking for more though.

 

He asked me if a 4 inch drop kit(?) for a GMT-800 would fit his GMT-400. I told him no. Am I right in doing so? It is a different frame afterall.

 

So, What could he do has far as lift? If he put an inch or 2 from the blocks and bars, should he try a 2-inch body lift? I also suggested some different torsion keys. Would they help as far as lifting the front end? Would 2500 bars do anything for it?

 

Thanks very much!
