Max tire size for 4 and 6 inch IFS 1998 GMC lift?

[Kyle97GMC]

woah did you go 6 inch?!

You know it! When I added my 3/4 ton leaf springs they added about two and a half inches out back. I also switched to 3/4 ton torsion bars and cranked to just about level. The rear is a little higher than the back still I just didnt want to crank the hell out of it

How does it ride now?

How does it ride now?

When I cranked it up originally on the 1/2 ton bars it rode like crap but when I put the 3/4 ton bars I swear it made the fronts ride quality a million times better!

With the 3/4t torsion bars, what keys did you end up running?

Ok so the deed is done/ has been done for about 4 months now.. I went with the SupeLift 6 inch lift and I love the ride ! HOWEVER--- Super lift did drop the ball on a few things 1) they said the kit was in but once I placed the order they called the shop and said they were out and it would take 4 weeks + to build the kit-- it took 6 weeks 2) when it came in and was minus several parts.. I had to wait 2 days to have then ship to me ( very sad on the quality control side ) but this seems so typical of American service now days..We have lost sight of customer service in this country... So Im not a big fan of Super Lift's service ... However the kit rocks!1 and I love the kit-- It was a pain to put on and took 3 days...But the lift works great and the truck sits an easy 6-1/2 inches higher than stock. I also went with the real lift TB re-locators these things rock and make the lift look so much better- I also went with rear add a leafs and shackle reverse shackles from ORD-- NO BLOCKS!! the combo is just stellar!! the truck is running on 35 MT/TTCs and it has never been a better ride- I love the ride -the height- the low tire noise- this was the right choice for me!! Thank you to everyone who gave input and advice I took everything to heart and made my choice and I am very happy. Thanks guys!! BTW if you use the same kit and shackle reverse I am pretty sure 37s are an easy fit w/o cranking any on the T-Bars I have a lot of room.. its craxy!! 37s will be next but 37 MT/TTCs until they bring back Ground Hawgs!! ( GOD I miss the Hawgs!!)

I had a 4 inch rcx on my 98 and was running 35s on stock 16 inch wheels without any trimming. Scrubbed my sway bar a little if I turned sharp. I know quite a few people running the same and hasn't done any trimming.

I ran 37s on a superlift with a 3 inch body lift. I wouldn't really suggest it, in myexperience the superllift kit is weak, the drop brackets on mine cracked in 2 separate places just being daily driven. maybe the have redisigned the kit but who knows.

Sorry man I just saw this but I used the 1/2 ton keys

Superlift still uses the old design. The lift I have is the older ( probably original) design rcx lift. I had to get a few parts for it from superlift cause its the same
