Dirt King DK-814904 Boxed Lower Control Arms for Toyota 150 Series

Manufacturer: Dirt King Fabrication
SKU: DRT-DK-814904

The Dirt King performance lower control arms are remarkably stronger compared to the factory lower arms. We replaced the weak factory ball joints with FK 1" stainless steel uniballs for strength and additional articulation. To attach the lower arm to the spindle we include high grade 17-4 stainless steel misalignment spacers with grade 8 mounting hardware. For the inner pivots we replaced the soft factory bushings with our custom machined delrin bushings. There are several major advantages of using delrin bushings compared to the softer bushings such as stock and polyurethane. The delrin bushings eliminate forward and backward movement of the lower arm along with allowing for a freer range of upward and downward motion unlike the injected factory bushings. They are also tabbed to accommodate for bump stops and limit straps to be used if you choose. The arms come fully assembled and include detailed instructions for easy installation.
