ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your Sierra level with the rear. Our torsion keys are designed to grab the “FLAT” of the torsion bar for a tighter, sturdier fit. CNC machined adjuster bolt pockets and 10.9 grade metric hardware allow for proper bolt seating, ensuring an accurate and safe adjustment. Only ReadyLift® torsion keys are forged, making them 25% stronger than OEM and primed to last the life of your vehicle.

The adjustable 66-3050 torsion key provides 1.5” to 2.5” of lift and gives clearance to add up to 33" wheels and tires to the Sierra. ReadyLift® keys are guaranteed never to affect the OEM ride and will not add more pressure on the stock suspension components. Through our innovative engineering, ReadyLift® kits cost thousands less than a traditional lift kit and install in about an hour.

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.

    ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your Silverado 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!

    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. 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.
