GMC Sierra: 1999-2007, Classic 4WD - 6 LUG - 2.5"
Front Leveling Suspension - Forged Torsion Key - 66-3000
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 66-3000 torsion key provides 1.5” to 2.5” of lift and gives clearance to add up to 33" wheels and tires to the 1999-2007 Classic GMC Sierra 4WD 6 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.
Kit includes new shock mount extensions and hardware.
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 Tow Package
3" GMC Rear Lift Blocks(66-3003)
- 2" GMC Rear Lift Blocks (66-3002)
ReadyLIFT® OEM style rear block kits are now available for 1999 and new GM Trucks. These Rear Block Kits include (2) Rear Blocks, (4) E-Coated U-Bolts, (8) Nuts and Washers and will safely lift the rear of your Truck an additional 1” to 3” depending on application. Based on OEM designs and never made out of light weight extrusions our 3" GM Blocks are made from cast iron and have Anti-Rotation ears built-In. Fits 1999-2010 classic and new body style 6-lug model GM trucks. New models with OEM 1" blocks will want to take advantage of the additional 2" of lift for towing and hauling, particularly when using a front leveling kit while classic body style 6-lug trucks will benefit from the rake created by 3" of rear lift.
ReadyLift® Block Kits will put a slight rake back in your Truck for hauling or towing and are designed to work in concert with your ReadyLift® Suspension Leveling Kit. Like all ReadyLift® products these block kits come with our Lifetime Warranty.
Also Available: NEW ReadyLIFT Tie Rod Reinforcement Kit
The GM OEM tie rods are slender and can weaken, bend or even break during aggressive off roading or harsh driving with heavy over-sized tires and wheels. ReadyLift developed a precision CNC-machined heavy-duty steel reinforcement sleeve that threads onto your OEM tie rods to provide strong support over the length of the tie rod. Easy to install.
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.
The adjustable 66-3000 torsion key provides 1.5” to 2.5” of lift and gives clearance to add up to 33" wheels and tires to your vehicle. 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.

bought this for my wife's Tahoe. My biggest worry was that the ride would be affected but that wasn't the case. Kept the ride and got me the lift I wanted. Overall good kit. (Posted on 1/28/14)
It's great and doesn't effect the ride of your truck Review by Jd
Price Value Quality
This a great leveling kit and is not expensive. It doesn't crank your torsion bars tight and it's safe. It keeps your truck driving the same as before you put it on and and it doesn't bother your shocks. Great buy!! (Posted on 10/31/13)
