I've been shopping around for a 2-3" lift that will let me run a little bigger tire. I'm on a tight budget so I've been looking at torsion keys as well as blocks or shackles for the rear. I've come across a few on eBay that look okay but I've only got 55k miles on this truck and need to make it last so I'm not excited about setting it up for premature wear on the front end. However I like the look of the Rough Country 170H kit that includes the upper control arms, diff drop bracket, shock brackets, etc. and add-a-leafs for the rear. (http://www.roughcountry.com/chevy_4wd_88-98_2-3.html) It's a little more money but could be worth it. This is my daily driver so I'm going more for street appeal than hardcore offroad capability, but I do get off the beaten path every once in a while. Wondering if anyone else out there has seen or installed this kit and can share any thoughts? My truck is a 99 GMC Sierra Classic (88-98 body style).
