Fabtech’s Uniball Upper Control Arms for the 2007–18 Chevrolet Silverado 1500 and GMC Sierra 1500 2WD/4WD, as well as the 2007–14 Chevrolet 1500 SUV/SUT and GMC 1500 SUV/SUT 2WD/4WD—engineered to fit 0–6″ lift systems—deliver a substantial increase in front suspension strength by replacing the factory upper arms and ball joints that can weaken or fail under aggressive off-road use. These heavy duty arms are built for long-term performance in rugged conditions and include additional caster for improved on-road handling and alignment when using oversized tires.
Expertly crafted using .120" wall, 1.50" OD 4130 Chromoly tubing, these arms offer greatly reduced flex for a more responsive and stable driving experience. They feature 1" FK Stainless PTFE-lined Uniballs for exceptional articulation and durability. The heat-treated 17-4 Stainless Steel Uniball pins fit directly into the factory ball joint taper with no spindle modification required, ensuring quick installation and the ability to return the vehicle to stock if desired.
Fabtech integrates 17-4 Stainless Steel misalignments to ensure proper clearance of the 1" Uniballs throughout the full suspension travel range. High-quality urethane bushings on the frame side help minimize road noise while providing excellent longevity. These Uniball Upper Control Arms are ideal for drivers demanding the highest levels of durability, strength, and performance from their suspension—whether stock or lifted.
