KSP PERFORMANCE Silverado 2500HD Upper Control Arms | Heavy-Duty 2-4 Inch Lift

Upgrade Your Silverado 2500HD with KSP PERFORMANCE

Engineered for tough jobs and demanding drives, the KSP 2-4" Upper Control Arms replace factory components with a thicker DOM tubular profile that delivers improved structural integrity for heavy-duty trucks. Designed for 8-lug 2020-model Silverado 2500HD, 3500HD, and Sierra 2500HD/3500HD trucks, these UCAs are built to endure challenging terrains and heavier loads while preserving steering control and alignment consistency.

Real-world use often reveals how essential a robust front suspension is when the road gets rough. The enlarged polyurethane bushings provide a longer service life and a smoother ride, while the greaseable socket design helps reduce wear by flushing contaminants from the joint and allowing fresh lubricant to circulate. A CNC-machined, high-frequency heat-treated ball joint is paired with a durable ball pin, offering a strong, precise fit that stands up to daily driving, highway stretches, and occasional off-road sessions.
