Fabtech K1181DL Uniball Upper Control Arm Lift Kit with Dirt Logic Shocks - 3.5

The Fabtech K1181DL is a premium 3.5-inch suspension lift kit engineered specifically for 2020-2021 GM K3500HD trucks. This comprehensive system enables fitment of up to 35-inch tires while significantly enhancing off-road capability and creating a more aggressive, leveled stance.

Uniball Upper Control Arms:

The centerpiece of this system is Fabtech's robust Uniball Upper Control Arms, which replace the factory GM components. These heavy-duty arms are constructed from premium 4130 Chromoly tubing with 1.50-inch outer diameter and .120-inch wall thickness, dramatically reducing flex compared to stock arms for improved road feel and handling precision. High-quality 1-inch FK stainless steel PTFE-lined Uniball bearings replace traditional ball joints, providing superior durability in rugged off-road conditions. The 17-4 heat-treated Uniball pin fits directly into the factory ball joint taper without spindle modification, allowing easy return to stock configuration. These control arms incorporate additional caster for enhanced alignment capability with oversized tires and increased wheel travel.

Suspension Components:

• Forged torsion bar keys for front lift and ride height adjustment
• 2-inch rear lift blocks with U-bolts for level stance
• Premium Dirt Logic 2.25 shocks with stainless steel body and NitroSteel piston rod
• 17-4 stainless steel misalignment spacers for proper geometry

Dirt Logic Shock Technology:

Fabtech's top-tier Dirt Logic 2.25 shocks feature corrosion-resistant stainless steel construction with NitroSteel piston rods. These high-performance dampers deliver superior ride quality both on-road and off-road, with excellent damping characteristics optimized for demanding off-road use while maintaining comfort during daily driving.

This complete lift system provides the strength, reliability, and commanding presence that serious off-road enthusiasts demand, with engineering designed specifically for heavy-duty GM 3500HD applications.
