The Fabtech K1129 Uniball Upper Control Arm system is engineered specifically for the 2019-2020 Chevrolet Silverado and GMC Sierra 1500 models. This suspension system lifts your ride by 3.5 inches over stock, enhancing ground clearance without compromising suspension performance. The lift is achieved using high-quality steel spacers that work seamlessly with the factory coilover shocks, ensuring a smooth ride on and off the road.
Constructed from .120" wall 1.50" OD 4130 Chromoly tubing, the Uniball Upper Control Arms are built to withstand the rigors of rugged off-road conditions. Instead of traditional ball joints, this system utilizes 1" FK Stainless PTFE lined Uniball bearings, which provide superior durability and a more responsive feel during on-road driving. The rear lift is accomplished through 1.5" blocks and u-bolts, paired with Fabtech's Performance shocks, ensuring a balanced ride height and improved handling.
This system is designed to accommodate larger tires, providing increased fender clearance compared to standard leveling kits, allowing fitment for 33" tall tires. Note that installation can restore the suspension to stock height if desired, giving you flexibility based on your driving needs.
