XRAY have introduced new composite graphite rear upright for the XB2, XB4 and XT2. The super-compact rear upright made from specially-formulated graphite composite material features multiple set-up options for upper and lower roll centers. The upper roll center is adjustable via camber linkage and shims, up/down and in/out. The lower roll center is adjustable via eccentric inserts in 9 different positions, up/down & in/out.

The race-proven, 2-piece design allows fine-adjustment and increases durability as well as performance. The graphite rear uprights make the car more stable and increases cornering speed as well as overall strength of the car. The uprights are small in size but are very strong due to the special composite mixture used. Suitable for most track conditions, especially for medium- and high-traction tracks, the upright fits on both left and right sides.
