Fabtech K1154DL Lift Kit with Dirt Logic Coilovers for GM Trail - 1.5 2019-2020 1500 Boss/AT4

The Fabtech K1154DL is a specialized 1.5-inch lift system engineered specifically for 2019-2020 GM K1500 pickup trucks equipped with the Trail Boss or AT4 package. This lift kit is designed to work with the factory 2-inch lift already present on these models, providing a combined 3.5-inch total lift height—equivalent to a standard model with a 3.5-inch lift kit—while maintaining proper suspension geometry and allowing clearance for full-size 33x12.50 tires on 18-inch or 20-inch wheels.

Key Components and Features:

• Dirt Logic 2.5 Stainless Steel Coilover Shocks: Premium front coilovers featuring corrosion-resistant stainless steel bodies and NitroSteel piston rods for exceptional durability and performance both on and off-road
• Tubular Upper Control Arms: Heavy-duty construction with extended-range ball joints addresses suspension geometry at the new ride height, ensuring proper alignment capability and a smooth, quiet ride
• Dirt Logic 2.25 Rear Shocks: Stainless steel body construction with NitroSteel piston rods delivers superior damping and corrosion resistance for demanding off-road conditions
• 1-Inch Rear Lift Blocks and U-Bolts: Provides rear lift to match the front; blocks are optional for those preferring a level stance
• No Differential Drop Required: Takes advantage of the 2019+ GM suspension geometry, eliminating the need for differential drop brackets while maintaining proper CV axle operation

Benefits:

• Increased ground clearance and fender space for 33-inch tires
• Avoids suspension bind at full droop unlike some lift solutions
• Suspension can be returned to stock configuration if needed
• Straightforward installation process
• Outstanding on-road comfort with excellent off-road capability

This budget-friendly system delivers premium performance with legendary Fabtech quality, making it an ideal choice for Trail Boss and AT4 owners seeking additional lift height without compromising ride quality or vehicle functionality.
