Dirt King Tubular Upper Control Arms [Silverado ZR2]

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. Features: CAD designed  Formed steel bushing gussets Constructed with 4130 chromoly tubing Preassembled for fast installation Maintenance free bushings Zinc plated components for corrosion resistance Durable black powder coat Professionally
