Great service and fast shipping from Lift Kits for Leas. Kit was straight forward to install. Took about 15 hours or so with a lift (first time doing a lift). I was very skeptical with ride quality but am amazed at just how smooth and good it rides. I coupled it with 35x12.5 Toyo rough terrain tires on older BMF Novakaine 20s and couldn’t be happier with the overall look and ride quality. The truck was recently leveled with 3” blocks in the rear and torsion keys up front with 305s. The look was good but it never fit right to the size of the truck. The only other part I would suggest are beefier tie rods with more adjustability for alignment up front. Thanks LK4L!

Been waiting to purchase a lift kit, they were running a black Friday special and I pulled the trigger. Super fast shipping, all packages were in great condition upon arrival, highly recommended using this company for a lift kit

I bought this kit during a sale they had on, not expecting a whole lot since it's a cheaper lift. I must say, I was very impressed with the build, the powder coat, and the instructions. Took my about 9 hours in my driveway by the time I got the wheels straight enough to go for an alignment. I imagine on a lift, on a truck with less rust, it could be done in much less. My torsion bars wouldn't come out of the keys so I took the crossmember and the bars as an assembly which took added time. All in all, a great kit that rides nice and doesn't look bad either. I'm running 37x12.5r16.5s with a little trimming. I actually see a lot of similarities with the more expensive BDS lift on my friends truck and then even some things I like better. Can't go wrong with this lift, not a bad install for a diy'er and little front diff modifications required

Installed this kit on my son's 2002 GMC Sierra 2500HD. I own an auto repair business and installed many kits over the years. Very impressed with the quality and ride on this one. Was able to clear 325/60/20 tires on 20x12 rims with some front bumper trimming. Only recommendation is to make the instructions on brake line and abs wire routing and mounting clearer.
