ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your vehicle 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 designed 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
2000-2010 GMC Sierra 3500 2wd & 4wd 8-lug. For information about tire and wheel sizes please visit the ReadyLift
Tire Sizing and Calculator Page.
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.
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 Torsion Key Unloading Tool
If you plan on installing the ReadyLift® Leveling Torsion Key then you will need a torsion key unloading tool to get the job done safely and effectively. Torsion keys possess the entire force of the torsion bars and even in a full droop position, the keys are still under a load. Torsion Key Unloading Tools are the ONLY safe method for removing and installing torsion keys. ReadyLift® offers the only Forged Torsion Key Unloading Tool. This tool is HIGHLY RECOMMENDED if you plan to do the installation yourself.
