ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your vehicle level with the rear. Our engineers have carefully measured the new Avalanche suspension to arrive at the optimum ride height increase--adding too much height will result in a suspension that easily "tops out"; creating damaging metal to metal contact and altering the OEM ride.
The Patented adjustable 66-3090 Strut Extension (
US Patent 7665743) allows you to run up to 32” tires and easily mounts on top of the strut assembly; eliminating the hassle, time and danger of compressing springs. Made from machined 6061-T6 Billet Aluminum, the 66-3090 strut extension will maintain a smooth OEM ride without deterioration or added pressure to the stock suspension components, guaranteed!
Fits 2007-2010 2wd & 4wd Avalanche - 6-lug.

Installation is simple and requires no strut preloading, cutting, or modification of factory installed parts. While other kits cost thousands to buy and hours to install, ReadyLift® can be installed one to two hours and costs less than the price of a single custom wheel.
ReadyLift Lifetime Warranty Included! All ReadyLift® products are backed by a lifetime warranty for as long as you own your vehicle and includes all necessary parts, hardware, detailed installation instructions, and two color decals.
