This is the SUPERLIFT Level-It 2.5 inch Leveling Kit for a big list of Chevrolet and GMC 1500 Pickups & SUVs. Built from quality material; comes at a good price; it’s a simple Remove & Replace item; truck looks great & has a more aggressive stance… great review.

This #40008 Leveling Kit fits the 1999-2006 Chevrolet Silverado 1500 4WD, 2002-2006 Chevrolet Avalanche 1500 4WD, 2000-2006 Chevrolet Tahoe 1500 4WD, 2000-2006 Chevrolet Suburban 1500 4WD, 1999-2006 GMC Sierra 1500 4WD, 2000-2006 GMC Yukon 1500 4WD and the 2000-2006 GMC Yukon XL 1500 4WD.

Superlift's Level-It lift systems are the perfect solution for anyone wanting an economical and easy way to eliminate the factory nose-down rake on virtually all late-model trucks and SUVs. Whether it's simply leveling the truck's stance, making the room to go up a couple of tire sizes, or plus-sizing the tire and wheel package on the vehicle, Level-It components work with factory suspension components to achieve modest ride height gains Super-EZ install.

The 1999-2006 Chevrolet Silverado 1500 4WD, 2002-2006 Chevrolet Avalanche 1500 4WD, 2000-2006 Chevrolet Tahoe 1500 4WD, 2000-2006 Chevrolet Suburban 1500 4WD, 1999-2006 GMC Sierra 1500 4WD, 2000-2006 GMC Yukon 1500 4WD and the 2000-2006 GMC Yukon XL 1500 4WD are all equipped with an Independent Front Suspension (IFS) with torsion bars.

In these IFS torsion bar models, the front tires attach to steering knuckles. The knuckles pivot on ball joints attach to upper & lower control arms. The upper & lower control arms position the knuckles front-to-back & side-to-side. The ‘spring’ of the suspension is a torsion bar. The torsion bars have a tremendous pre-load or ‘twist’ in them. The torsion bars are what determine the ride height of the suspension. These torsion bars have a certain amount of adjustment built into the factory system, but simply ‘cranking up’ the factory system will cause a more harsh ride.

The front of the torsion bar attaches to the lower control arm and rear attaches at a rear frame crossmember. This crossmember houses the adjuster or torsion keys. Torsion bar keys have hex-cut (or splined) holes that mate to the rear ends of the torsion bars. This adjustment takes place via a bolt that indexes on a torsion key attached to each torsion bar.

Our Level-It keys are indexed differently to increase bar rotation and lift (the center hex where the torsion bar mounts is re-indexed or rotated). As the new keys are loaded, they apply torsional load to the bars which in turn lifts the vehicle greater than that of the stock torsion keys. Ours are also designed to grab the ‘flat’ hex portion of the torsion bar for a more precise, tighter fit.

SUPERLIFT Level-It keys are improved direct replacements for the factory keys included in all these year, make & models: 1999-2006 Chevrolet Silverado 1500 4WD, 2002-2006 Chevrolet Avalanche 1500 4WD, 2000-2006 Chevrolet Tahoe 1500 4WD, 2000-2006 Chevrolet Suburban 1500 4WD, 1999-2006 GMC Sierra 1500 4WD, 2000-2006 GMC Yukon 1500 4WD and the 2000-2006 GMC Yukon XL 1500 4WD.

NOTE: Special torsion bar puller tool is required to load/unload torsion bars. The puller tool is available for purchase or rental from most major automotive part stores.

IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers' wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.

• Installation time: 3 hours
• Difficulty level: 2 of 5

NOTE: Special torsion bar puller tool is required to load/unload torsion bars. The puller tool is available for purchase or rental from most major automotive part stores.
