Billet Upper Control Arms

Dirt King Billet Upper Control Arms – Engineered for Strength, Style & Silence

The Dirt King Billet Upper Control Arms are CNC-machined from 6061 aluminum, delivering exceptional strength, durability, and a high-end billet finish. These Dirt King upper control arms are designed to optimize suspension geometry on GM1500 upper control arms platforms, offering the clearance needed for added front lift and increased suspension travel—especially when paired with Dirt King shocks. While Factory Series arms often limit articulation and compromise geometry, Dirt King addresses this with improved caster settings and re-engineered pivot angles for enhanced handling, stability, and wheel travel.

A major highlight of these Silverado upper control arms is the advanced inner pivot system. The maintenance-free Probearing SilentSpin bushings feature a polyurethane outer layer that reduces vibration and noise, paired with a self-lubricating composite core for smooth, quiet motion. This design delivers excellent on-road comfort while maintaining the off-road control expected from Dirt King components.

Each arm comes equipped with heavy-duty Probearing ball joints, providing outstanding durability and long-term reliability in demanding environments. Built for easy installation and engineered for lasting performance, these billet GM1500 upper control arms are a premium upgrade for any Silverado 1500 or Sierra 1500 owner looking to improve strength, ride quality, and suspension capability.
