Dirt King Ball Joint Upper Control Arms | 07-18 Silverado/Sierra 1500

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 stock arms. We solved these problems by designing our upper control arms with increased castor and repositioned pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. We upgraded the ball joints to heavy duty Moog joints for maximum strength and increased articulation. For the inner pivots we use durable delrin 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.
