COMPOSITE UPRIGHT REAR - MEDIUM

XRAY 323353-M Composite Rear Upright - Medium Super-compact rear upright made from MEDIUM-hardness composite material. Perfect balance between reliability and performance, for use on left or right side. Features 7 different upper roll center positions. The rear uprights have 0° toe to ensure stability and to prevent suspension geometry changes in hard crashes. It also features a hole for the set-screw that secures the pivot pin in place. The rear upright molded from MEDIUM-hardness composite is suitable for most track conditions, especially very-low & low-traction tracks. For maximum drivetrain reliability, larger 5x12mm ball-bearings are used in the outer position to handle increased dynamic load. On the inner position, smaller 5x10mm ball-bearings are used to minimize unsprung weight.
