Fabtech Uniball Upper Control Arm Kit for 2007-2018 Chevrolet Silverado/GMC Sierra 1500 (Fits OE Forged UCA, 0-6" Lift) - FTS21128

Fits 2007-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models originally equipped with OE forged upper control arms. This Fabtech Uniball Upper Control Arm Kit is engineered for trucks with 0 to 6 inches of lift, providing the increased strength and alignment capability required for leveled or lifted applications.

These arms replace the factory ball joints with high-strength 1-inch ID stainless steel American-made uniballs. Constructed from heavy-duty chromoly tubing, they significantly reduce the flex found in stock components for a more precise road feel. The included 4340 heat-treated uniball pins are precision-machined to fit the factory spindle taper without modification, ensuring a secure fit and the ability to return to stock if necessary.
