These CST Torsion Lift Keys # CSK-C13-3 can provide between 1" to 2" inches of additional lift on the 2011+ 2500HD and 3500 series GM trucks. A question that many 4wd owners often ask is won't these keys ruin my 4wd driveline? - The simple answer is no. Most of the suspension lift kits made by BDS, Fabtech, ProComp, RCD, Rancho, and others use a replacement lift steering knuckle (aka steering upright or spindle) that increases the operating angles of the front CVs the same amount as a torsion key lift does. These suspension lift kits are well respected and have proven to be extremely reliable and are popular with customers. Vehicles with over 100,000 miles have reported no failures due to the slight increase in CV joint operating angle. CST Performance Suspension believes that the small increase in front drive line angle is not enough to cause concern among 4wd owners, however a slight increase in CV boot wear is possible and should be watched.

For the 2wd owners this is an EXCELLENT upgrade that will help to level out a stock truck and can also be used to provide an additional 1-2 inches of lift to an existing CST 6-8" or 8-10" Suspension Lift System. These Torsion Lift Keys work very well to help level the new GM trucks that arrive from the factory with a noticeable front to rear rake.

New shocks are not mandatory however suggests the installation of a slightly longer and more performance oriented shock absorber. For this reason, offers CST Performance Suspension Dirt Series and Bilstein 5100 Series replacement shocks for use with these torsion lift keys. For customers that are also raising the rear of their truck we also offer longer than stock replacement rear shocks too.

Installation Notes: strongly recommends getting the vehicle re-aligned after installing these torsion lift keys - failure to do so may lead to premature tire wear and poor handling. The CSK-C13-3 includes 1 Pair of CST Forged Torsion Lift Keys and Shock Extensions - enough to lift the front of one vehicle. These Torsion Lift Keys will not fit any 1500 series standard duty GM trucks or SUVs! If you are looking for an easy way to lift the rear of your truck PerformanceLifts offers 2500HD and 3500 specific Rear Block and U-Bolt Kits available separately below.
