Sierra 1500 2019-2026 GMC - Upper Control Arm Kit by Kryptonite

Address the weak points of your GMC Sierra 1500's front suspension with the Kryptonite's KRUCA19 Upper Control Arm Kit—engineered to correct the OEM design’s shortcomings and deliver unbeatable durability and performance. The factory setup places a steel stud inside an aluminum cup with minimal reinforcement, leading to premature failure—especially on leveled trucks. Kryptonite’s solution? A high-articulation ball joint built specifically for the unique geometry of the new GM 1500s, paired with boxed, heavy-duty upper control arms that increase suspension travel, stability, and strength.

Whether you're running a stock, leveled, or lifted setup, these UCAs improve articulation and ride quality without compromising factory components. Designed with integrated mounts for ride height sensors and brake lines, this bolt-on upgrade is made in the USA and backed by Kryptonite’s legendary Lifetime Warranty. Get ready to transform your truck’s handling and off-road capability with confidence.
