This high-quality 6″ lift kit for the 2020–2024 Chevy Silverado 3500HD and GMC Sierra 3500HD (4WD) is engineered to significantly enhance off-road capability while maintaining a smooth and controlled highway ride. Designed to preserve the truck’s factory load-carrying capacity, it is an excellent choice for owners who depend on their vehicle for towing, hauling, and demanding work applications.
At the core of this system is Fabtech’s cutting-edge RTS® design. This innovative bracket system retains the torsion bars in their factory location while providing lift, maximizing ground clearance and eliminating the risk of the torsion bars hanging low or becoming damaged during off-road use. The result is a cleaner, more streamlined undercarriage appearance with improved obstacle clearance.
The lift kit also includes heavy-duty lower control arm crossmembers engineered with an arched underside for additional ground clearance. These crossmembers feature an integrated skid plate to shield the front differential from rocks, debris, and off-road impacts. Constructed from 1/4″ thick steel, the crossmembers and bracketry deliver superior strength, rigidity, and long-term durability.
Fabtech’s thoughtful engineering enables a quicker installation with only four drilled holes required and no cutting of the front differential housing. This maintains the integrity of factory components while delivering a secure, precise fit.
Built with high-quality materials and designed for long-lasting performance, this heavy-duty lift kit provides years of reliable service while offering improved ride comfort, greater off-road capability, and enhanced vehicle stance.
CROSSMEMBERS
1/4″ thick steel lower control arm Crossmembers are arched for maximum ground clearance. The welded box design of these Crossmembers provides additional strength to the front suspension. Retains factory alignment cams for easy adjustment.
STEERING KNUCKLES
Fabtech’s extended length ductile iron Steering Knuckles provide zero bump steer throughout the suspension travel. This provides an enhanced driver experience compared to stock. Near stock track width keeps the tires under the fenders for a clean appearance.
TIE RODS
Oversized tie rods are provided to replace the stock units that are designed to handle oversized tires.
SKID PLATE
A heavy duty front differential Skid Plate is constructed of 1/4″ thick steel to protect the diff from offroad obstacles.
DIFFERENTIAL MOUNTS
Heavy duty Differential Mounts properly reposition the front diff for the precise CV and driveshaft angle to reduce driveline vibration at high speed.
SWAY BAR MOUNTS
Heavy duty mounts reposition the front sway bar for on road functionality and no bind for offroad use.
Front & REAR BUMP STOP SPACERS
Steel brackets relocate the 4 front and 2 rear compression stops to align with the factory closed cell bump stops to control the travel and eliminate over cycling of the suspension.
REAR LIFT BLOCKS
4″ tall rear lift blocks replace the factory blocks for additional lift without changing the ride quality or load carrying capacity. This block height helps level the truck front to rear.
REAR U-BOLTS
U-Bolts designed to attach the entire rear differential to the vehicle. A critical part that demands the best quality for your vehicle.
Stealth Shocks
These extended length monotube shocks have a Nitrocarb piston rod for corrosion resistance and resist rock chipping. Great highway ride with good offroad damping capacity.
