About the kit...
First things first... the CST 6-8" lift will clear a 35" tire. And yes, it provides between 6" inches and 8" inches of front suspension lift. You can adjust the front lift height using the factory adjustment feature on the torsion bars. This lift is 100% Stabilitrak compatible. This is the CST S.T.L Kit - Stock Torsion Location. This lift is designed to offer the maximum ground clearance by keeping the torsion bars tucked up under the framerails. If you don't like the look of a torsion bar drop kit this lift is for you! CST spent a considerable amount of time designing a High-Clearance Stock Torsion Location kit capable of withstanding off-road use and abuse. With the High-Clearance design the Torsion Bars are less likely to get hung up on off-road obstacles such as rocks or stumps. Even if you don't take your Silverado or Sierra off-road this kit design looks awesome and cleaner than most torsion bar drop down kits do.

CSK-C3-17-1 Features:
Similar to the standard 6-8" kit, this adjustable suspension lift kit includes the famous CST 1-Piece gusseted High Clearance sub-frame with a full size steel differential skid plate. The Fabricated Steel front steering knuckles feature CNC machined components. The high strength steering drop center link has Rod End equipped support links to minimize wear of factory idler and pitman arms. Other included items are the differential drop brackets, heavy duty bump stop brackets, extended sway bar end links, brake line drop brackets, all necessary hardware, and front stock shock extensions. Steering stabilizer brackets are built into the kit and the CST Stabilizer Shock can be purchased as an option. Every fabricated component is covered in a durable Black powder coat finish. The drop subframe is a welded 1-piece design that holds an alignment much better than other "bolt together" designs. No welding is required to install this lift and the truck can be returned to stock height if necessary. The CSK-C3-17-1 Base Kit includes adapters that allow you to retain the factory front shock (upgraded front shocks are available). The rear of the truck is lifted via a pair of Fabricated 4" Rear Lift Blocks and Extended Length 3/4" U-Bolts.

Please note this lift is designed for use with the 2011 and newer model year Chevrolet Silverado 2500HD, 3500, and GMC Sierra 2500HD and 3500 single rear wheel trucks. CST recommendeds that the tire size not exceed 35" inches when lift is adjusted to provide 6" inches of lift. Larger tires may be run when the maximum 8" lift height is set. CST Torsion Lift Keys are required to achieve the maximum 8" of lift and are not included but can be purchased separately. The recommended maximum wheel back space is 5.25" when running 17" diameter wheels and 5.75" when running 20" diameter wheels.
