Fabtech 2020 GM K2500HD/3500HD UCA 3.5in Lift System

Starting with replacement upper control arms featuring .120 wall DOM construction and heavy-duty extended range ball joints, this 3.5-inch lift system from Fabtech is built for strength. These arms are paired with heavy-duty, extended-length steering knuckles designed to maintain proper Electronic Stability Control (ESC) functionality even with 35-inch tall tires. The knuckles also keep the factory track width, ensuring your tires stay tucked neatly under the front fenders.

To ensure proper CV angles throughout the suspension's travel range, the front differential is relocated. The front suspension is completed with bump stop extensions and brake hose relocation brackets. For the rear, a 1-inch lift block and U-bolt system is included to level the vehicle's stance. This system is designed to work with your factory coilover shocks and rear performance shocks, simplifying the installation process. The entire setup is designed for a straightforward installation with no drilling, welding, or cutting required, and it doesn't reduce your ground clearance or necessitate driveshaft modifications.
