The Fabtech K1155DL is a premium suspension lift kit engineered for 2020-2021 GM 2500HD trucks, delivering 2-3.5 inches of increased ride height for running up to 35-inch tires with enhanced off-road capability. This complete system levels the vehicle's stance front to rear while dramatically improving suspension performance and wheel travel.

Uniball Upper Control Arms:

The centerpiece of this kit is Fabtech's engineered Uniball Upper Control Arms that replace the factory GM units. Constructed from premium 1.50-inch OD, .120-inch wall 4130 Chromoly tubing, these arms eliminate flex found in stock components for a more positive on-road feel. High-quality 1-inch FK stainless steel PTFE-lined Uniball bearings replace traditional ball joints, providing superior strength and longevity in rugged off-road conditions. The arms feature additional caster built-in compared to stock for enhanced alignment capability with oversized tires.

Advanced Engineering Features:

• 17-4 heat-treated Uniball pin fits factory ball joint taper without spindle modification for easy installation and return-to-stock capability
• 17-4 stainless steel misalignments ensure proper clearance of large Uniballs throughout full suspension travel range
• Billet aluminum Uniball caps for maximum durability
• Forged torsion bar keys replace factory units and allow additional ride height adjustment

Dirt Logic 2.25 Shock Absorbers:

This kit includes Fabtech's top-tier Dirt Logic 2.25 shocks featuring stainless steel bodies and NitroSteel piston rods for maximum corrosion resistance and durability. These premium shocks deliver superior ride quality both on-highway and off-road with excellent damping characteristics for aggressive terrain.
