Fabtech 14-18 GM K1500 w/OE Alum. UCA 4in Uniball UCA System w/Rear Perf. Shocks

The .120-inch wall, 4130 Chromoly tubing used in these upper control arms is a strong foundation for a lift kit that's built to handle tough terrain. This Fabtech 4-inch Uniball UCA System is designed for your 2014-2018 Chevrolet Silverado 1500 or GMC Sierra 1500, giving you the clearance needed for up to 33-inch tall tires while maintaining a comfortable ride.

Instead of just spacers, this system replaces your factory upper control arms with robust tubular Uniball arms. These arms feature 1.50-inch OD tubing and 1-inch FK Stainless PTFE Uniballs, allowing for unrestricted suspension movement and improved articulation, especially important for aggressive off-road driving. The kit also includes a front differential relocation system to ensure proper CV angles with the added lift, and a 1/4-inch thick steel skid plate to protect vital components from trail obstacles. For the rear, a 1.5-inch lift block and U-bolts help level the truck's stance, and performance rear shock absorbers are included to enhance damping over stock units.

This kit offers a mild lift height that's easy to install and can be restored to stock configuration if needed. It provides increased fender clearance compared to a simple leveling kit, making it a solid choice for those looking to fit larger tires and improve their truck's off-road prowess.
