Fabtech 20-21 GM K2500HD 3.5in Uniball UCA Kit w/Dlss Resi

This Fabtech Uniball UCA Lift System gives your 2020-2021 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a 3.5-inch increase in ride height, allowing you to fit larger 35-inch tires and achieve a more aggressive stance. It replaces the factory upper control arms with Fabtech's own Uniball Upper Control Arms, which are built from .120-inch wall, 1.50-inch OD 4130 Chromoly tubing. These arms use 1-inch FK Stainless PTFE lined Uniball bearings instead of traditional ball joints, offering increased wheel travel and a more direct on-road feel by reducing flex.

The kit also includes Fabtech's Dirt Logic 2.25 shocks, featuring stainless steel bodies and NitroSteel piston rods for excellent corrosion resistance. The front shocks come with remote aluminum reservoirs to help manage heat and maintain consistent damping performance during demanding off-road use. The system incorporates forged torsion bar keys to provide additional ride height adjustment, working in harmony with the new control arms. The Uniball UCA's are designed with extra caster built-in to help with alignment when running larger tires, and the 17-4 heat-treated Uniball pin fits the factory spindle taper without modification, making installation straightforward and allowing for an easier return to stock if needed.

This comprehensive kit is designed to add strength and reliability to your HD truck's suspension while giving it a commanding presence. It includes the necessary components to upgrade your front suspension, along with the Dirt Logic shocks to handle both on-road comfort and off-road capability.
