Dirt King Fabrication Boxed Upper Control Arms - 4Runner/FJ/Prado/GX

Overview:
 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 UCA’s. We solved these problems by designing our arms with increased castor and repositioned pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. We have also replaced the weak factory ball joints with 1” stainless steel uniballs for maximum strength along with increased articulation. For the inner pivots we used durable urethane bushings with zerk fittings for easy servicing of bushings, and heavy duty FK heims for additional adjustability in the arm for heimed arms. 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.
