I just got a new (to me) 2001 4x4 with 3.55LS and have spent a couple days reading the forums. ive been looking at installing a Rough Country 2.5 kit and running a set of 315/70/17 that I bought for my old truck. Everything that I've read has been 50/50 saying that you shouldn't run the kit because of our front ends. So if I was to get that kit would 315/70/17's fit? Or should I just sale those tires and run a set of 285/70/17's with stock suspension and torsion bars cranked just a little bit? Thanks for the help guys!

 

Welcome to the forum!

The new kit you're looking at lifts the front with torsion bars. Your stock torsion bars most of the time can get you up to the max recommended height of 24.25" from the center of the hub to the fender. After market keys will let you go over that (stock keys will too, but aftermarket one will make it worse). The kit only gives you a 1" lift block for the rear and that's all I would use, but then you're stacking blocks. A better way to go is put an add a leaf in the rear.

You can fit 315's on your truck as it stands with no lift, and just a T-bar crank. I hated that ride on my truck, I rubbed on everything because I didn't want to cut too much off of my truck.

If it where my truck, I personally wouldn't screw with anything. If anything I'd keep the tires on it and crank the T-bars a little bit.

 

Thank you for the welcome! Kind of leaning towards putting the 315/70/17's on Craigslist and just sticking with 285/70/17's and leaving the suspension alone.
