If you are going to tow, be careful going to 18" wheels. Load range E 18" tires get expensive. Stick with the stock 16's or 17's.

U can run 285's with turning the torsion bars and trimming the front bumper support and bending the inner fender support at the bottom of the firewall back a little.

Also, depending on what gears are in it, it will only tow worse with any bigger tires than 245 or 265.

As far as lifts rough country has lifetime warranty on their lifts including the shocks. I have had great success with their products and customer service.
 
ok thanks might just have to go to 265 for now and lift it later on. what do you have to do to level it out do i need to buy a leveling kit?
 
You can get it close to level with just turning the torsion bars up.

A leveling kit usually comes with new torsion keys that do the same thing, but allow you to crank the bars even farther, as well as shock extenders.

Be careful of turning the bars too much as it will ride terrible and eventually over travel the bars.

As well, you MUST get an alignment after turning the bars as the camber will be off slightly and the toe in will be off an inch.

We currently own 5 2500 subs and have had another.

One reason to keep the suburban over a truck is that you can tow up to the max weight the mfr recommends using regular car tags. The suburban tag costs $29 or something cheap like that while the 17k tags on my avalanche are ~$250.

Suburbans are titled as passenger carrying vehicles not property carrying vehicles allowing this "loophole" to apply.

thanks i did not know that even more reason for me to keep it and you sad you own 5 subs what years motor and trans you got and what trans is behind the 6.0L v8 not a allison is it?
 
We had a 93 tbi 350, but sold it

97 454
97 350
99 454
01 6.0
13 5.3
Also my 04 avalanche 2500 which is all suburban underneath with the 8.1

All 2500 suburbans have the 4L80E, and then the newer ones with 8.1 have 4L85E

Suburbans never had the Allison, the frame is not tall enough for the trans. One of the many reasons the 2500hd and above frames are taller than regular 2500s and suburbans.

I dd the avalanche, and then drive either the 99 454 or 01 6.0 towing a loaded 12' enclosed trailer for work everyday.

thanks mac5005
 
I haven't verified it, but have heard you can use factory GM 1500 keys to lift a 2500. Kind of like how you can use f150 keys to lift a GM 1500. Again, have never tried it. a lot cheaper then buying a set of "lift keys" and chances are the torsion bars are fatigued from age/ miles so you may not have much adjustment in the bolts. Have to just slide under and look.
