CSK-G18-7 | CST Suspension 4 to 6 Inch Stage 7 High Clearance Suspension System (2011-2019 Silverado, Sierra 2500 HD, 3500 HD 2WD/4WD)

ADJUSTABLE 4-6” CST S.T.L. (STOCK TORSION LOCATION) HIGH CLEARANCE LIFT KIT.

THIS CST KIT WILL LIFT THE 2011-2019 CHEVY/GMC HD A TRUE 4 INCHES WITHOUT DROPPING THE TORSION CROSS MEMBER DOWN OR COMPROMISING THE RIDE!

This adjustable 4 to 6 inch S.T.L. (Stock Torsion Location) High Clearance design for the 11-19 Chevy / GMC HD trucks provides the “leveled look” without sacrificing the ride quality or function.

We’ve combined our experience in off road racing with trophy truck quality engineering to ensure that your suspension will have increased strength, performance, overall build integrity and perform better than stock. Throughout the initial design and R&D process we made sure to retain the factory O.E. suspension geometry and design attributes!

This adjustable kit includes gusseted high clearance cross-members with a full size differential skid plate, cast-iron / CNC machined front steering knuckles, differential drop brackets, heavy duty bump stop brackets, extended sway bar end links, brake line drop brackets, all necessary install hardware, and O.E. front shock extensions. This stage 5 kit also includes six 2.0 reservoir shocks & front dual shock mounts. Steering stabilizer brackets are built into the kit and our stabilizer shock kit can be purchased as an optional upgrade. For the rear this 4-6″ kit includes BILLET 1″ lift blocks and heavy duty, zinc-plated u-bolts.

No cutting of the front differential is required or welding of any kind to install this kit. Retaining the factory front wheel track width allows this kit to work perfectly with all of the trucks stability assist features including the GM StabiliTrak system.
