7" 2011-2019 GMC Sierra 3500HD 2WD/4WD Lift Kit by Skyjacker

Boost your 3500HD's stance and capability with Skyjacker’s C1178KH heavy-duty suspension lift kit—engineered for strength, reliability, and real-world performance. This system raises suspension clearance, allowing you to run up to 35-inch tires while maintaining proper steering geometry and seamless compatibility with the OEM Electric Stability Control (ESC) system.

Heavy-duty ductile iron CNC-machined steering knuckles ensure optimal CV angles and geometry throughout suspension travel. Paired with robust front and rear drop crossmembers and a differential skid plate, the kit forms a rigid subframe that supports the lower control arms and protects key driveline components. Skyjacker’s raised torsion bar brackets deliver high ground clearance with a clean, integrated look. The system also includes all necessary hardware for a complete front and rear lift, including front bump stop brackets, sway bar links, brake lines, differential relocation brackets, and rear cast ductile iron blocks with heavy-duty Grade 8 U-bolts and lock nuts. Whether you're hitting the job site or the trail, this complete lift system brings out the best in your 3500HD—built to handle more, look tougher, and ride with confidence.
