Dirt King Billet Upper Control Arms | 2003-2024 4Runner / FJ Cruiser / GX460 / GX470

Dirt King Billet Upper Control Arms provide 0-3" lift, improved suspension geometry, and max down travel. Features maintenance-free SilentSpin bushings or ¾” chromoly rod ends with heavy-duty ball joints.

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.
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.
