This high-quality 3.5" HD suspension lift kit is engineered for 2020-24 Chevrolet Silverado 3500HD and GMC Sierra 3500HD 4WD models, delivering increased ride height for enthusiasts looking to run 35" tall tires with enhanced off-road capability. The system levels the vehicle from front to rear, creating a more aggressive stance while maintaining stable and predictable on-road performance.
The factory upper control arms are replaced with Fabtech heavy-duty tubular ball joint upper control arms designed to withstand the demands of heavy-duty use. These arms are constructed from 1.50" OD DOM steel tubing and feature oversized high-travel ball joints that are significantly larger than stock, providing increased strength, durability, and articulation for both on-road driving and off-road environments.
Fabtech precisely sets the ball joint angle to allow full suspension travel without binding throughout the entire range of motion. Forged torsion bar keys replace the factory units, allowing additional ride height adjustment while working in conjunction with the upgraded upper control arms to maintain proper suspension geometry and alignment.
The rear suspension is leveled using 2" rear lift blocks and U-bolts, helping retain ride quality and load-carrying capacity. This system is equipped with Fabtech’s top-of-the-line Dirt Logic 2.25 shocks, featuring stainless steel shock bodies and NitroSteel® piston rods for maximum corrosion resistance and durability. The front shocks include remote aluminum reservoirs to help manage heat and provide consistent damping during aggressive off-road use.
This 3.5" HD lift kit is built with premium components that enhance strength, reliability, and overall vehicle performance while giving the truck a commanding presence on and off the road.
