Refine Balance with the XRAY 343310 Rear Upright

Developed for older RX Series models, the XRAY 343310 rear composite upright brings multiple tuning options to your setup toolkit. Its features are focused on delivering consistent, repeatable changes to handling behavior.

Selectable Roll Center Settings to Tune Balance

The upright provides two upper roll center choices so you can influence lateral weight transfer. Switching positions helps tailor the rear grip and rotation characteristics to match track demands and driving preference.

Body Mount Versatility for Different Shells

Two body mounting positions allow you to fit a range of shells without compromising handling. This makes it easier to pair different body styles to your preferred setup while keeping consistent dynamics.

Accurate Setup via Pivot Balls and Bushings

Support for both short and long pivot ball joints lets you adjust leverage and geometry with precision. The concentric and eccentric bushings enable roll center shifts and independent wheelbase tuning for a detailed approach to handling setup.
