XRAY 363350 Rear Upright Composite V2 Vintage XB Series Tune Part  [XR-363350]

Compact composite upright for improved XB handling

The XRAY 363350 Composite Upright Rear - V2 is made for the vintage XB series and gives racers a compact, sturdy option to sharpen rear-end stability. The unit includes two roll centre positions on the lower mount and three positions on the upper mount for fine tuning to different track conditions.

Stable geometry with 0 degree toe

Manufactured from a specially formulated composite, these rear uprights balance small size with high strength for dependable service. The 0 degree toe layout helps keep suspension geometry consistent under load, reducing unwanted changes during heavy impacts for more predictable handling.

Bearing layout for durability and response

The outer hub location accepts larger 5x12 ball bearings to handle higher dynamic loads, while the inner hub uses 5x10 bearings to reduce unsprung mass and sharpen suspension response. This combination keeps the drivetrain running smoothly without excess weight.
