Dirt King Billet Upper Control Arms – Engineered for Strength, Style, and Silence
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 the 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 inner pivot system. 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. These allow for optimal on-road and off-road performance, delivering excellent handling with no compromises.
These are equipped with heavy-duty Probearing ball joints for long-lasting durability in harsh environments. The billet upper control arms are built for lasting performance and easy installation, making them an excellent upgrade for any vehicle.
Wheel Travel / Lift: The Dirt King billet upper control arms must be paired with aftermarket shocks and torsion keys to lift the vehicle. These arms offer maximum down travel compared to the stock UCAs and are compatible with Dirt King, King, Fox, Bilstein, ADS, and Icon shocks.
