If you're looking for a performance lift that puts you up in the air while putting the competition to shame you've found the right kit. This CST Lift kit achieves 6" of lift in the front, and 5" in the rear, allowing you to easily run 35" wheels.

This lift kit comes with a new subframe for the front with related bracketry, supported upper control arm drop mounts, steering drop downs with heim jointed support linkages, a new cross bar, and more. These components will drop your factory suspension down a true 6", keeping steering and axle angles correct. Newer GM models with the Stabilitrak system can use this kit without problems. Torsion keys can also be added (sold separately) to achieve up to an additional 2" of lift. Some vehicles may need driveline modifications or additional rear lifting if you choose to add torsion keys in addition to this lift kit.

You will need to use aftermarket shocks when you install this lift kit. You can purchase the CST shocks above for an additional fee, or you can purchase your own elsewhere.
