Geometry Plus control arms offer more than just a high-tech appearance. Designed to improve suspension, the arms provide more straight-line stability, better corner entry and overall vehicle response. The main concept is keeping as much of the tire on the ground as possible during all conditions. This is done with different length control arms, which directly affect the tilt of the tire in relationship to the pavement. Arms are fully assembled, including ball joints and bushings, which are available in the revolutionary Del-A-Lum design. Del-A-Lum bushings are fully greasable and feature a no drag design that will not work harden and wear-out. All arms are TIG-welded for strength and powder coated gloss black for outstanding looks.
