Fabtech’s Uniball Upper Control Arms for the 2011–19 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD 2WD/4WD—specifically engineered to fit 3.5" lift systems only—deliver a significant upgrade in suspension strength and reliability. By replacing the factory ball joint upper arms that can wear out or fail under aggressive off-road use, these heavy duty arms provide long-term durability in rugged conditions. They also feature additional caster for improved on-road handling and enhanced alignment performance when running oversized tires.
Constructed from premium .120" wall, 1.50" OD 4130 Chromoly tubing, these arms minimize flex and enhance steering precision for a more controlled and confident driving experience. Each arm is equipped with 1" FK Stainless PTFE-lined Uniballs for exceptional articulation and maximum service life. The heat-treated 17-4 Stainless Steel Uniball pins install directly into the factory ball joint taper without requiring spindle modification, ensuring easy installation and the ability to return the vehicle to stock if desired.
Fabtech incorporates 17-4 Stainless Steel misalignments to ensure proper Uniball clearance throughout the full suspension travel range. High-quality urethane bushings on the frame side help reduce road noise while maintaining excellent durability. These Uniball Upper Control Arms are an outstanding upgrade for lifted HD trucks and ideal for drivers demanding superior strength, precision, and off-road capability.
