Ball Joint Upper Control Arms All, Probearing Bushings

Upgrade your Ford Bronco’s front-end performance with Dirt King UCA, the premium choice for anyone seeking better suspension geometry and long-term durability. These Bronco upper control arms are designed to deliver proper alignment correction and support additional lift when paired with aftermarket shocks—something stock arms can’t handle without stressing Factory Series joints or compromising structural strength.

The re-engineered Bronco UCA design improves caster for sharper handling and optimizes pivot angles for increased articulation off-road. Inside, the Probearing SilentSpin bushings offer the ideal blend of smooth, free-spinning performance like poly bushings—without sacrificing the maintenance-free benefits of OE elastomer.

Heavy-duty Moog ball joints replace the Factory Series units to ensure maximum durability in harsh terrain, and every component is fully rebuildable or replaceable for long-term serviceability. Each set arrives preassembled with detailed instructions, making installation straightforward and hassle-free.

Take your Bronco’s suspension performance to the next level with Dirt King.
