(Stock Torsion Location) High Clearance design provides the leveled look without sacrificing the ride quality or function.
CST combined their 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.

This adjustable kit includes gusseted high clearance, fully boxed 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. Steering stabilizer brackets are built into the kit and our stabilizer shock kit can be purchased as an optional upgrade. For the rear the 3-6" 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. The 3"-6" Adjustable Lift Height provides a level stance at 4" of lift with 1" rear blocks installed. With no permanent modifications, this lift kit requires no welding and does have the ability to be put back to stock. With superior CV & Tie-Rod angles, the S.T.L High Clearance Lift provides a stock ride, and handling. All fabricated parts are covered in a high quality gloss black powdercoat finish.
