CST Performance Suspension Stage 1 Lift # CSK-C3-15-1 will provide between 6-8" inches of lift depending on how it is adjusted. This lift is designed for use on the 2011, 2012, 2013, 2014, 2015, 2016, 2017 and 2018 model year Chevrolet Silverado 2500HD and GMC Sierra 2500HD and 3500 series trucks. And yes, this lift fits both 2wd and 4x4 models. CST designed their all new lift to provide 6.5" inches of suspension lift with the torsion bars set to the factory setting. Because the CST lift is a true 6.5" lift, you can adjust the total front suspension lift from 6" inches up to 8" inches over factory height. At the 6.5" lift height setting the CST kit easily clears most 35" diameter tires. With the kit adjusted to provide the full 8" inches of lift the use of up to a 37" diameter tire is possible with minor trimming.

The CST fabricated steering knuckles and 1-piece welded subframe have been design to retain the factory track width. Every CST component used in this suspension lift have been built to exceed the strength of the factory GM components they replace. And to protect the factory components, CST includes a front differential skid plate. All of the major components are powder coated in a high quality Gloss Black finish. The rear is lifted using a fabricated steel 5" tall lift block with a built-in bump stop pad. Extended length 3/4" wire diameter U-bolts are included to complete the block installation. Speaking of installation, no welding is required to install this suspension system and the vehicle can be returned to stock if necessary.

Shock Absorber Options:
The factory front shock absorber is retained with the CST CSK-C3-15-1 Foundation Kit. CST includes a shock spacer bracket that retains the original factory installed front shock absorber. Upgraded front shock absorber options are available for those looking to upgrade their Basic lift to a Performance oriented version. CST does not include but offers a number of different rear shock options. The CST Street Series # CSR-2500 rear shock is their least expensive options. The CST Dirt Series 2.0 Emulsion and Dirt Series 2.0 Reservoir rear shock options are also available using the selection boxes located beneath this item description.

Wheel Options:
The CST CSK-C3-15-1 Suspension Lift is 100% compatible with factory wheels and factory size tires. Please note, when running larger than stock tires a 17" or 18" wheel with no more than 5.25" inches of back space should be used. If running a 20" or larger diameter wheel, maximum back space can be increased to a maximum of 5.75" inches. The factory spare tire can be installed and driven on without the need for a wheel spacer. Please note, the new 2011+ and newer 2500HD series trucks now use an 8x180mm lug pattern. This 8 on 180mm lug pattern is unique to the 2011 and newer 2500HD GM trucks. The Dual Rear Wheel trucks have a different pattern than the 2500HD trucks.

2016 and Newer Trucks:
GM has made some small revisions to the 2016 model year that required CST to produce 2016+ specific parts for use with their kits. The CSS-C22-12 Emergency Brake Bracket Kit is necessary to properly relocate the factory emergency brake cables. If you will be installing the CST High Angle Dual Cardan front driveshaft you will need to also purchase CST # CSS-C22-13 - Transmission Shift Linkage Bracket Kit. These items are both available for purchase using the selection box titled 2016+ Accessories.
