Suburban 4X4 suspention question

I have a 1990 Chevy V2500 3/4 ton 4X4, and I've noticed that the front leaf spring are sagging. "sad smile" I want to swap the leafs out to at least make it level or have alittle bit of a lift to it. I dont want to have to change brake lines, and drop the transfer case and all that. My question is should I run a 2" or 4" lift spring in the front. Ive heard I can run a 4" leaf spring in the front without having to mod the exhaust and brake lines and all that except maybe the steering. I dont use the truck for crazy off road, only in sand and mud/dirt.

Re: Suburban 4X4 suspention question

I just did a 4in spring swap and only had to buy new shocks. The brake linesare fine and no drop needed at the transfer case.

Re: Suburban 4X4 suspention question

I have a 4in lift and a 3in body and the only mod was a common lift mod the brake lines get drop down brackets the exhaust I see no reason to get modded with either and the steering you'll most likely need the raised pitman arm or whatever its called can't think of it but it levels the steering so there's no massive right or left turn
