Dirt King | Billet Upper Control Arms Application: 2010-2023 Toyota 4Runner Features and Benefits: T The Dirt King Billet Upper Control Arms are precision-machined from 6061 alumin um, 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. We recommend the bushings for optimal on-road and off-road performance, delivering excellent handling with no compromises. Alternatively, the traditional ¾” chromoly rod ends offer a firmer, performance-driven connection for those prioritizing responsiveness and control in demanding off-road conditions. The rod ends also feature threaded adjustment sleeves, allowing precise camber and caster adjustments while the arms remain installed. 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.
