This gives you the clearance and ability to add wheels and tires up to 32.5" in diameter. While other lift kits cost thousands to buy and hours to install, ReadyLift can be installed in about two hours by a certified mechanic, and costs less than the price of a single custom wheel. ReadyLift products do not affect the factory OEM ride quality or comfort. Our engineers have carefully measured the Yukon and Sierra 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 smooth OEM ride. ReadyLift Strut Extensions, unlike urethane strut spacers, never wear out, never need to be re-torqued, and do not affect the OEM-quality ride. ReadyLift Strut Extensions are made from machined 6061-T6 Billet Aluminum. They mount on top of the strut assembly, eliminating the hassle, time and danger of compressing springs. That's why ReadyLift also offers a lifetime warranty for as long as you own your vehicle against defects for all of our products.
