  • ReadyLIFT® leveling kits are the fastest, safest, least expensive way to bring the front of a 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 2” to 3” of lift and gives clearance to add up to 33" wheels and tires to the 2wd & 4wd 2000-2010 Silverado 1500/2500 HD 8-lug. 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 1-2 hours. 

    For those who install heavy front items such as snow plows, the ReadyLift torsion keys will allow you to adjust your suspension to compensate for the extra weight, as well as give you the opportunity to not only increase the lift amont, but adjust it to suit while maintaining your factory ride. 

    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.
