Fabtech K1162DL 6" RTS Lift Kit System with Dirt Logic SS Reservoir Shocks for 2020-2021 GM 3500HD 4WD

The Fabtech K1162DL is a premium 6-inch lift system engineered specifically for 2020-2021 GMC Sierra and Chevrolet Silverado 3500HD 4WD trucks. This complete suspension system dramatically improves off-road capability while maintaining a comfortable highway ride and preserving the factory load-carrying capacity essential for towing and hauling applications.

Revolutionary RTS (Raise The System) Design:

At the heart of this lift kit is Fabtech's innovative RTS bracket system, which keeps the torsion bars in their original factory frame location while providing full lift height. This design delivers superior ground clearance at the frame by eliminating low-hanging torsion bars that can be damaged or cause high-centering during off-road use. The RTS brackets index the torsion bars at factory settings to maintain the smooth, factory-like ride quality.

Heavy-Duty Construction:

• 1/4-inch thick steel crossmembers and brackets provide exceptional strength and rigidity
• Arched lower control arm crossmembers maximize ground clearance
• Integrated skid plate protects the front differential from trail obstacles
• Welded box-design crossmembers for superior structural integrity
• Front and rear bump stop brackets prevent suspension over-cycling

Dirt Logic SS Reservoir Shocks:

This system includes Fabtech's premium Dirt Logic SS reservoir shocks, featuring high-pressure nitrogen gas charging and velocity-sensitive valving for exceptional performance on and off road. The remote reservoir design provides increased oil capacity for superior heat dissipation and consistent damping performance under demanding conditions.

Installation and Fitment:

Engineered for straightforward installation with only four drill holes required and no cutting of the front differential housing. The kit maintains near-factory track width to help keep tires positioned under the fenders. All necessary hardware and detailed instructions are included for a professional installation.

This complete lift system is designed and manufactured in the USA using premium materials for years of trouble-free service in the most demanding applications.
