6-7" 2014-2018 GMC Sierra 1500 Lift Kit by Skyjacker

The Skyjacker C14660APK 6-7 Inch Suspension Lift Kit for 2014-2018 GMC Sierra 1500 4WD models is engineered to deliver maximum ground clearance, superior suspension performance, and the durability needed for serious off-road use. Designed to retain the factory front struts while dramatically increasing ride height, this complete suspension system provides clearance for up to 33-inch tires and maintains proper steering geometry through premium engineered components. Multiple shock options are available, allowing the suspension to be customized for everything from daily driving to high-performance off-road adventures.

The system features CNC-machined ductile iron replacement steering knuckles that preserve factory steering geometry throughout the suspension's travel, along with heavy-duty front and rear crossmembers precision laser cut and formed for exceptional strength. Durable differential drop brackets and CNC-machined 6061-T6 aluminum front CV axle spacers reposition the front driveline to maintain proper CV and driveshaft operating angles. A heavy-duty differential skid plate ties the crossmembers together to create a rigid subframe while protecting critical steering and drivetrain components from off-road hazards.

Skyjacker's innovative two-piece front strut spacer system retains the factory GM-tuned struts while safely achieving additional lift. The lower strut extension provides increased ride height, while the upper one-piece spacer utilizes a precise pitch-and-index design to maintain proper CV axle extension within factory tolerances. Additional components including brake line extension brackets, ABS extension brackets, sway bar drop brackets, extended rear sway bar links, and rear lift blocks with heavy-duty U-bolts ensure proper suspension operation throughout the full range of travel. Choose from Skyjacker Black MAX shocks, Hydro 7000 hydraulic shocks, Nitro 8000 nitrogen-charged shocks, M95 monotube shocks, ADX 2.0 Adventure Series monotube shocks, or premium ADX 2.0 Adventure Series Remote Reservoir shocks featuring Internal Floating Piston (IFP) technology for exceptional damping control, heat dissipation, and off-road performance.
