Dirt King Fabrication Uni Ball Upper Control Arm Kit for Chevy / GMC Silverado / Sierra 1500 DK-635902

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 also replaced the weak factory ball joints with 1” stainless steel uniballs for maximum strength and increased articulation. For the inner pivots we use durable delrin bushings with grease fittings for easy servicing. To mount the arms to the spindle we include high grade 17-4 stainless steel misalignment spacers and grade 8 hardware. 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.
