4" 2014-2018 GMC Sierra 1500 Lift Kit by Skyjacker

The Skyjacker C14460APK 4-Inch Suspension Lift Kit for 2014-2018 GMC Sierra 1500 4WD models is engineered to deliver exceptional ground clearance, improved suspension geometry, and the strength needed for both daily driving and serious off-road use. This complete suspension system replaces critical front suspension components with heavy-duty engineered parts, providing clearance for up to 33-inch tires while maintaining factory steering characteristics and compatibility with the vehicle's Electronic Stability Control (ESC) system. Multiple premium shock options allow the suspension to be tailored for everything from comfortable street driving to aggressive off-road performance.

At the core of the system are CNC-machined ductile iron replacement steering knuckles that preserve proper steering geometry throughout the suspension's travel. One-piece strut spacers feature a precise pitch-and-index design that maintains proper CV axle operating angles without overextending factory components. CNC-machined 6061-T6 aluminum differential spacers and front CV spacers further correct driveline geometry, while heavy-duty CNC laser-cut front and rear crossmembers provide rigid mounting points for the factory lower control arms and exceptional long-term durability.

The rear suspension utilizes lift blocks and heavy-duty U-bolts to achieve a level stance while maintaining dependable load-carrying capability. Choose from Skyjacker Black MAX shocks for dependable everyday performance, Hydro 7000 hydraulic shocks for a smooth factory-like ride, Nitro 8000 nitrogen-charged shocks for improved control, M95 monotube shocks for enhanced handling and fade resistance, or premium ADX 2.0 Adventure Series Remote Reservoir shocks featuring an aluminum monotube body, Internal Floating Piston (IFP) technology, race-inspired valving, and a remote reservoir for maximum damping performance under demanding conditions. Designed to fit models equipped with OEM aluminum or stamped steel control arms, the C14460APK delivers the strength, capability, and ride quality expected from a premium suspension system.
