Dirt King® Ball Joint Upper Control Arms

2003+ Toyota 4Runner

So you've lifted your 4Runner, you're wheeling harder, and your stock control arms just aren't cutting it anymore. If you want quality and made in the USA, Dirt King® has your answer, with their Upper Control Arms.

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. They solved these problems by designing their arms with increased castor and repositioned the pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. They have also upgraded the factory ball joints with heavy duty Moog ball joints. For the inner pivots they used durable urethane bushings with grease fittings for easy servicing. All of the components on their 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.
