XRAY 343310 Rear Composite Upright - Off-Road and Track Tuner  [XR-343310]

Tweak Balance with XRAY #343310 Rear Upright

The XRAY #343310 Rear Composite Upright is built to help drivers refine chassis balance and tyre contact. Intended for older RX series kits, it brings simple, repeatable changes to handling setup.

Roll Centre Choices for Handling

Two upper roll centre positions let you control lateral load transfer to suit cornering style. Small adjustments here can produce noticeable differences in rotation and stability.

Body Mount Versatility

Two distinct body mount options make it straightforward to fit a range of shells while keeping suspension geometry intact. That versatility helps when swapping bodies between races.

Pivot Ball Variants and Bushings

Supporting both short and long pivot balls along with concentric and eccentric bushings, the XRAY #343310 enables roll centre shifts and wheelbase variation for tailored handling. Use the combinations to find what works on your track.
