Adding a couple inches to 4Ē suspension lift.

I got a 1991 suburban 3/4 ton 4x4 about a year ago finally getting started on it. The PO never mentioned any lift but Iím about 80% sure itís got a 4Ē lift already on it, is there a way i can confirm this? I threw on a 315-75/16 to check my offset of the wheels and they fit pretty good except when i run obviosuly it rubs the fenders. (See second pic)

If it already has a 4Ē lift, i know i can add 2Ē block in the rear but i donít want to put blocks on the front and Iíd rather stay away from body lifts. The additional 2Ē is temporary, just until i can get a 6Ē suspension lift. I just want something i can add now so i can get these 35ís on it.

Also some research Iíve done shows this truck possibly has the 4l80e transmission. The pan does have 17 bolts but i donít know how else i could determine which tranny it has.

Re: Adding a couple inches to 4Ē suspension lift.

do this http://www.offroaddesign.com/catalog/oneinchlift.htm

with this http://www.offroaddesign.com/catalog/bodymounts.htm

and http://www.offroaddesign.com/catalog/Zero%20Rates.htm

last in 2.5" flavor http://www.offroaddesign.com/catalog/shacklekit.htm
or another zero rate in the rear with no flip kit .

gets you 2" total . levels the rear a bit with the 2.5"flip kit in rear or the 1" only in rear with another zero rate kit. . and new body bushings to replace the 40+ year old rubber ones .

you will need new u-bolts with these items.

Re: Adding a couple inches to 4Ē suspension lift.

I donít like adding blocks at all. But, I have a 4 inch lift on my 87 pickup and I run 35s daily and mine doesnít rub at all. Maybe you only have a 2 inch or 3 inch lift????

I like what i see, i didnít realize they made aluminum body lifts, i didnít want to use body lifts because Iíve heard they crack. I work at a steel fab shop and have access to a CNC plasma table, could i make my own pucks out of mild steel?

Thatís possible, i looks like the tire only the ribs the flare not really the fender itself. But i have driven it around with 35s either. Either way it seems i only need a couple inches to clear anyways.
