Fabtech 20-21 GM K3500HD 3.5in Bj UCA Kit w/Stealth

If you're looking to give your 2020 or 2021 Chevrolet Silverado 3500 HD a more aggressive stance and the ability to clear larger tires, this 3.5-inch lift kit from Fabtech is a solid option. It directly replaces key suspension components to increase ride height, level the front and rear, and prepare your truck for 35-inch tall tires, all while enhancing its offroad capabilities.

This kit swaps out the factory upper control arms for Fabtech's own heavy-duty tubular arms. These are built from 1.50-inch OD DOM steel tubing and feature a larger, high-travel ball joint that's stronger than stock. Fabtech carefully sets the ball joint angle to allow for full suspension travel without binding. The kit also includes forged torsion bar keys that replace the factory ones, giving you additional ride height adjustment. In the rear, 2-inch blocks and U-bolts are included to help achieve that leveled look. For the shocks, this system comes with Fabtech's Stealth shocks. These are sealed monotube units with a Nitrocarb piston rod that resists corrosion and rock chipping, offering a comfortable highway ride and capable offroad damping.

Beyond the increased height and tire clearance, this kit adds strength and reliability to your truck's suspension. The tubular steel upper control arms include an additional 1 degree of caster, which can help with alignment after the lift. The rear Dirt Logic 2.25 shocks feature a stainless steel body and NitroSteel piston rod for excellent corrosion resistance and durability, providing superior ride quality and damping for offroad use.
