Tacoma's, FJ's, and 4Runner's run out of factory adjustment on the UCAs when you install lift kits. With Light Racing's patent pending design this upper control arm provides an additional ±2° of caster and 0° to +5° of camber change. Built with an OE style ball joint and bushings, this arm is designed to correct alignment angles while maintaining factory ride quality. The hybrid tubular and forged steel design is tough enough to race on or off-road. These replacement upper control arms are available in pairs for lifted and off-road applications or individual left and right arms if just one corner needs adjustment.
