Dirt King 19-22 Silverado/Sierra 1500 Heim Upper Control Arms (DK-636903)

Dirt King Heim Upper Control Arms for the 2019-2022 Silverado/Sierra 1500 2WD/4WD increases castor and repositions pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. Dirt King also replaced the weak factory ball joints with 1” stainless steel uniballs for maximum strength and increased articulation. For the inner pivots they used heavy duty ¾” FK heims for additional camber and caster adjustability. To mount the arms to the spindle they include high grade 17-4 stainless steel misalignment spacers and military grade F911 hardware. 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.
