Front Leveling Suspension - Strut Extension
ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your vehicle level with the rear. Made from machined 6061-T6 Billet Aluminum, the 66-3080 strut extension will maintain a smooth OEM ride without deterioration or added pressure to the stock suspension components, Guaranteed!
Fits 2007-2013 GMC Sierra 2wd & 4wd 6-lug
Our Smart Strut Technology mounts on top of the strut assembly, eliminating the hassle, time and danger of compressing springs. This allows you to run 32” wheels without altering your factory strut or pre-loading the spring and without having to cut the factory studs. 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.
