Great leveling kit and great price
This 1.75” readylift leveling kit fit my 2021 Silverado perfectly. All parts were accounted for and it installed with ease. I received it very quickly and it gave my truck a totally different look.

A must have for all Trail Boss/AT4 owners!
A must for any Trail boss/AT4 owner. This kit lifts the front of the vehicle 1.5 inches and the vehicle sits completely level from front to back. On top of that, I was able to upgrade to a bigger tire. I’m now using a 305/60/20 with 20x9 inch wheels with a 0mm offset. Fitting 35s in the truck with very minimal fender trimming is a big win. As for the parts themselves, extremely quality and much more durable than the factory control arms. The ride quality is not jeopardized at all, in fact, it seems to make the steering lighter. The install was very easy, but I would recommend a partner to help!

Easy install and looks great.
Lifted the front of my 1500 AT4 a little over 2 inches. 285/75/18 (35”) fit perfect.

Beware of denting, scratches, and paint chips on the control arm
A good product but I am being charged a restock fee for an item that showed up defective at my door. The packaging on this item is not good. The spacer bounces around on top of the control arm during shipping and causes dents, scratches and the paint to chip! This is unacceptable and I would appreciate you making this right. I should not be charged a restock fee, period.

Love the Level
The kit came complete, no missing parts. The upper control arm is quite beefy and keeps the factory dynamics . It gave my 2019 AT4 a better look and stance while keeping the original ride comfort.
