Overview

 Description

Dirt King 4130 UCA's – More Travel. More Control. More Confidence.

Built for high-performance off-road use, the Dirt King 4130 Upper Arms are a premium upgrade over our standard arms—equipped with Probearing Pro 4 Series Ball Joints that outperform traditional uniballs and Moog joints in strength, articulation, and steering control.

The 4140 Pro 4 ball joints feature an induction-hardened ball stud and sintered bearings, delivering unmatched side-load strength and a smoother on-road steering feel.

Combined with corrected suspension geometry, SilentSpin™ bushings, and 4130 chromoly construction, these arms are ready to handle whatever you throw at them.
