There are multiple issues when lifting your vehicle with stock upper control arms. Both the geometry and strength are compromised due to over articulating the factory arms. We solved these problems by designing our arms with increased castor and repositioned the pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. We have also upgraded the factory ball joints with heavy duty Moog ball joints. For the inner pivots we used durable urethane bushings with grease fittings for easy servicing. All of the components on our upper control arms are rebuild-able or replaceable to make this product last a lifetime. The arms come preassembled and include detailed instructions for easy installation.

Overview

DK-636991

The Dirt King ball joint upper control arms are engineered to improve suspension geometry, enabling additional front lift when paired with Dirt King 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 Dirt King 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.
