CST Performance Suspension 4" Stage 4 Suspension System # CSK-G23-4 is designed for use on the new 2020, 2021 and 2022 Chevrolet Silverado and GMC Sierra 2500HD / 3500 series trucks. With 4" inches of front suspension lift the new GM trucks can easily clear 35" tires and up to a 37" tire with minor lower valance trimming. And yes, this lift fits both 2wd and 4x4 models. CST designed their all new lift to provide 4" inches of suspension lift with the torsion bars set at the factory setting. Doing this provides a very smooth and compliant ride that soaks up the bumps like you can't believe. The CST drop subframes provide a true 4" inches of lift and from there you can adjust the torsion bar settings up to achieve additional ride height. This kit includes a 2" rear lift block and extended length U-bolts. Additional rear lift may be necessary to achieve the desired stance when the front suspension is set above the standard 4" inches of lif theight.

Tire & Wheel Information:
At the 4" lift height setting the CST kit can clear up to a 35" diameter tire on most 8" to 10" wide wheels. Use of 37" tires is possible but some light trimming will be required on the lower plastic valance (air dam). The use of low offset or wheels wider than 10" inches may require additional trimming to prevent tire rub when turning. For this reason CST recommends that wheels with a width of 8" to 9" inches be used.Factory GM 18" wheels are NOT compatible with this lift. Factory GM 20" wheels are compatible with this lift. When running larger than stock tires on an aftermarket 18" wheel the back space must not exceed 5.25" inches. When running a 20" or larger diameter wheel the back space must not exceed 5.75" inches. Use of wheels that are 10" inches or wider is against CST's recommendation due to the increased likelyhood that the front tires will rub when turning. If you want to run a WIDE wheel or a wheel with very low offset you can but the use of a smaller diameter tire may be required to prevent rubbing.

Stage 4 Shock Absorber Information:
The CST Stage 4 system includes a set of CST Dirt Series 2.0 Emulsion shock absorbers for the front and rear of your truck. The Stage 4 system also includes the CST Single Front Shock Mounting Kit # CSS-C33-4. The included Single Mounting Kit allows you to replace the factory front shock and replace it with the included CST 2.0 Dirt Series Emulsion shock. The factory rear shock is also replaced and installs using factory hardware.

Stage 4 Kit - What's Different?
The CST Stage 4 System includes everything from the Stage 3 system but adds the CST Fabricated Upper Control Arm Kit # CSS-C2-20. The Stage 4 System is CST's most advanced system that includes the 2.0 series non-reservoir shocks. If you are looking for reservoir equipped shocks you need to look at the Stage 5 and higher kits.
