Skyjacker’s C1178K 6-inch Suspension Lift Kit for the Chevy Silverado 2500HD is engineered to enhance strength, stability, and off-road performance while maintaining OE functionality and ride quality. Designed to accommodate tires up to 37 inches in diameter, this complete system increases ground clearance and reinforces critical suspension components for long-lasting durability and control.
Heavy-duty front and rear crossmembers provide a solid mounting point for the factory lower control arms. At the same time, a differential skid plate provides added protection for steering and driveline components, reinforcing the system. Dual differential relocation brackets maintain correct axle and driveshaft angles, preserving smooth 4WD operation. Skyjacker’s CNC-machined ductile iron steering knuckles ensure proper geometry and CV axle integrity throughout suspension travel. Raised torsion bar brackets provide a clean, high-clearance profile that aligns perfectly with the OEM torsion bar mounts. This bolt-on system seamlessly integrates with your factory suspension, including extended brake lines, sway bar links, bump stop brackets, and rear cast-iron lift blocks with heavy-duty U-bolts and hardware—everything needed for a complete front and rear lift system, ready for work or the trail.
