Dirt King Ball Joint Upper Control Arms | Toyota 4Runner (2003-2024)

The Dirt King Ball Joint Upper Control Arms are engineered to replace worn or weak factory upper arms with a stronger, more durable suspension component. These arms use heavy-duty ball joints rather than bushings at the outer pivot, which helps provide precise steering response and increased durability in demanding conditions. Built with a rugged steel design and reinforced where it matters, they offer improved handling and control whether you’re driving daily, hitting trails, or building a lifted suspension setup.

Each arm is designed to work within recommended suspension geometry, helping maintain proper alignment and articulation. These control arms are a solid upgrade over stock parts, providing a reliable performance foundation and reduced deflection under load.
