Description

The Dirt King ball joint upper control arms are engineered to improve suspension geometry, enabling additional front lift when paired with shocks. Lifting a vehicle with stock upper control arms compromises both the geometry and structural strength due to excessive articulation at the factory joints. The arms address these issues with improved caster settings for enhanced handling and re-engineered pivot angles for increased articulation. The inner pivots feature Probearing SilentSpin bushings, offering the ideal combination of a free-spinning inner sleeve, typical of poly bushings, with the maintenance-free and greaseless advantages of OE elastomer bushings. Additionally, the standard ball joints have been upgraded to heavy-duty Moog ball joints ensuring superior durability. All components of these upper control arms are rebuildable or replaceable, promoting long-term durability and ease of maintenance. These arms arrive preassembled with detailed instructions for a straightforward installation.
