Fabtech 20-21 GM K3500HD 3.5in Uniball UCA Kit w/Dlss Resi

If you're looking to fit larger tires and improve the off-road performance of your 2020-2021 Chevrolet Silverado 3500 HD, this 3.5-inch lift kit from Fabtech is a solid option. It's designed to give your truck a more level stance front-to-rear, giving it a more aggressive look while also enhancing its capability when you leave the pavement behind. This kit replaces the factory upper control arms with Fabtech's own Uniball Upper Control Arms, which are built to handle more stress and offer increased wheel travel.

These control arms are constructed from strong 1.50-inch OD, .120-wall 4130 Chromoly tubing, which means they're built to resist flex and provide a more direct feel on the road. Instead of ball joints, they use robust 1-inch FK Stainless PTFE-lined Uniball bearings, which are known for their longevity in tough conditions. The kit also includes Fabtech's forged torsion bar keys to help you fine-tune the ride height, and 2-inch blocks with U-bolts for the rear to achieve that level stance. For the shocks, you get Fabtech's top-tier Dirt Logic 2.25 shocks, featuring stainless steel bodies and NitroSteel piston rods for excellent corrosion resistance. The front shocks even come with remote aluminum reservoirs to help keep the shock oil cool during demanding off-road use, ensuring consistent damping performance.

This kit is designed to add strength and reliability to your Silverado 3500 HD's suspension while giving it a commanding presence. The built-in extra caster in the control arms also helps with alignment when you're running larger tires. You'll want to refer to the manufacturer's installation instructions for specific details on mounting and any additional hardware that might be needed.
