Fabtech K1161DL 6" RTS Lift Kit with Dirt Logic Shocks 2020-2021 GM 3500HD 4WD

The Fabtech K1161DL is a premium 6-inch lift system engineered specifically for 2020-2021 GM 3500HD 4WD trucks. This complete suspension lift kit enhances off-road capability while maintaining the smooth highway ride and factory load-carrying capacity essential for towing and hauling applications.

Revolutionary RTS (Ride Time System) Design:

The foundation of this lift kit is Fabtech's innovative RTS torsion bar bracket system. Unlike conventional lifts, the RTS keeps torsion bars in their factory frame location while providing lift. This design delivers superior ground clearance at the frame by eliminating vulnerable low-hanging components that can cause high-centering or damage during off-road use, while creating a clean, factory-like appearance.

Heavy-Duty Construction:

• Lower control arm crossmembers constructed from 1/4-inch thick steel for maximum strength and rigidity
• Arched crossmember design provides exceptional ground clearance
• Integrated skid plate protects front differential from trail obstacles
• Welded box construction ensures long-term durability
• RTS brackets index torsion bars at factory settings for optimal ride quality

Installation and Fitment:

• Streamlined installation requires only four drilled holes with no cutting of front differential housing
• Near-factory track width keeps tires properly positioned under fenders
• Front and rear bump stop brackets prevent suspension over-cycling
• Retains factory load ratings for full towing and payload capacity

Included Dirt Logic Shocks:

This system comes complete with Fabtech's Dirt Logic SS (Stainless Steel) performance shocks, engineered to handle the demands of lifted heavy-duty trucks both on and off-road.

The K1161DL lift kit represents professional-grade suspension engineering designed for GM 3500HD owners who demand maximum capability without compromising ride quality or truck functionality.
