3-3.5" 2011-2019 GMC Sierra 2500HD/3500HD Lift Kit by Skyjacker

Skyjacker C11350 3-3.5 Inch Suspension Lift Kit for 2011-2019 GMC Sierra 2500HD and 3500HD trucks delivers increased ground clearance, improved suspension geometry, and clearance for larger tires while maintaining reliable on-road handling. Designed as a complete bolt-on system, this kit includes Skyjacker's heavy-duty tubular upper control arms, torsion bar keys, front differential spacers, rear lift blocks, and your choice of rear shock options to tailor ride quality and performance to your driving style.

At the heart of the system are Skyjacker's DOM steel upper control arms, engineered to withstand the demands of both daily driving and off-road use. Constructed from high-strength Drawn Over Mandrel tubing with welded 1/4-inch gusset-plate reinforcement, these control arms provide greater rigidity and durability than factory components. Greaseable ball joints help extend service life while allowing for improved alignment correction on lifted applications.

The included torsion bar keys and differential spacer system provide 3-3.5 inches of front lift while maintaining proper driveline geometry. Rear lift blocks level the vehicle and create clearance for up to 33x12.50 tires on 18-20x9 wheels using OEM backspacing. Multiple rear shock options allow owners to choose among comfortable daily-driver performance, enhanced towing stability, or premium off-road damping.

Available rear shock options include no rear shocks for custom setups; Skyjacker Hydro 7000 hydraulic shocks; Nitro 8000 nitrogen-charged shocks; Black MAX twin-tube shocks; M95 monotube shocks; ADX 2.0 aluminum monotube shocks; or premium ADX 2.0 remote-reservoir shocks for maximum off-road performance and heat dissipation.
