HARD molded composite rear upright with 2 roll center positions made from super-tough, high-tech composite material. Compact size and superior strength give the perfect balance between reliability and performance.
This HARD rear upright is suitable for most track conditions, especially medium- and high-traction tracks.
The lower roll center adjustment has 1 fixed position on the upright, while the upper roll center adjustment has 3 different positions. The rear uprights feature 0° toe to ensure stability and prevent suspension geometry changes in hard crashes.
For maximum drivetrain reliability, larger 5x12mm ball-bearings are used in the outer position for increased dynamic load. On the inner position, smaller 5x10mm ball-bearings are used to minimize unsprung weight.
For use on either left or right sides.
