This premium 6″ lift kit for the 2020–2024 Chevy Silverado 2500HD and GMC Sierra 2500HD (2WD/4WD) is engineered to significantly enhance off-road capability while maintaining exceptional ride quality on the highway. Designed to retain the factory load-carrying capacity, it is ideal for truck owners who rely on their vehicle for towing, hauling, and demanding everyday use.
At the core of this system is Fabtech’s advanced RTS® design. This innovative bracket system keeps the torsion bars in their original factory location while providing lift. By maintaining the torsion bars at the frame, ground clearance is dramatically improved—eliminating the risk of the bars hanging low, catching obstacles, or being damaged during off-road driving. This design also gives the vehicle a cleaner, streamlined appearance.
The kit also includes heavy-duty lower control arm crossmembers engineered with an arched bottom for additional ground clearance. These crossmembers feature an integrated skid plate to protect the front differential from rocks and off-road impacts. Constructed from 1/4″ thick steel, the crossmembers and bracketry deliver exceptional strength and rigidity for long-term suspension durability.
Thanks to its high-quality engineering and precise fitment, the system installs efficiently with only four drilled holes and requires no cutting of the front differential housing. This preserves the integrity of factory components while reducing installation time.
Built with superior craftsmanship and robust materials, this heavy-duty lift kit is designed to provide years of reliable service while offering improved ride comfort, increased capability, and excellent all-around performance.
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
3″ 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.
Dirt Logic 2.25 Shocks
The stainless steel body with NitroSteel piston rod provides maximum corrosion resistance and durability. High quality componentry delivers a superior ride quality both on and offroad. Excellent damping for offroad use.
