Dirt King Billet Upper Control Arms | 2024-Present 4Runner / Tacoma

Dirt King billet upper control arms support 0-3” lift, improve geometry, and increase travel. Machined from 6061 aluminum with SilentSpin bushings or chromoly rod ends and heavy-duty ball joints for durable, reliable suspension performance.

The Dirt King Billet Upper Control Arms are precision-machined from 6061 aluminum, offering exceptional strength and a refined appearance. Designed to optimize suspension geometry, these arms allow for increased front lift and suspension travel when paired with Dirt King shocks.
Factory control arms often compromise geometry and structural integrity due to excessive articulation at stock joints, but Dirt King arms solve this with improved caster settings and re-engineered pivot angles for better handling and articulation.
A key feature of the billet arms is the adjustable inner pivot system, available in two configurations. The maintenance-free Probearing SilentSpin bushings provide superior ride comfort, with a polyurethane outer layer that dampens road noise and a self-lubricating composite core for smooth, quiet operation. Alternatively, the traditional ¾” chromoly rod ends offer a firmer, performance-driven connection for those prioritizing responsiveness and control in demanding off-road conditions.
Both configurations are equipped with heavy-duty Probearing ball joints for long-lasting durability in harsh environments. These billet upper control arms are built for lasting performance and easy installation, making them an excellent upgrade for any vehicle.
