About this part

Product Details

If you're looking to give your 2020-2021 Chevrolet Silverado 2500 HD a more aggressive stance and the ability to clear 35-inch tires, this 3.5-inch Uniball UCA lift kit from Fabtech is a solid option. It directly replaces your factory upper control arms with robust Uniball Upper Control Arms, which are designed to provide more wheel travel and an improved caster angle for better alignment, especially with larger tires. This kit also includes Fabtech's Dirt Logic 2.25 shocks, known for their excellent damping both on and off the road.

The Uniball Upper Control Arms are constructed from strong .120-inch wall, 1.50-inch OD 4130 Chromoly tubing, which significantly reduces the flex found in stock arms for a more connected feel on pavement. Instead of traditional ball joints, these arms use durable 1-inch FK Stainless PTFE lined Uniball bearings, offering increased strength and longevity for rugged offroad use. The kit also incorporates forged torsion bar keys that allow for additional ride height adjustment, working in harmony with the new control arms to achieve that desired level stance. The included Dirt Logic 2.25 shocks feature stainless steel bodies and NitroSteel piston rods, offering strong corrosion resistance and durability.

This comprehensive kit is designed to add strength and reliability to your HD truck's suspension while giving it a commanding presence. The 17-4 Heat treated Uniball pin fits the factory ball joint taper without needing to modify the spindle, making it easier to return the vehicle to stock if needed. The kit also includes stainless steel misalignments to ensure proper clearance for the large Uniballs throughout their full range of motion.
