XRAY 303351 Composite Right Rear Upright - Precision Rear End Part  [XR-303351]

Improve turn-in with the XRAY 303351 rear upright

The XRAY 303351 Composite Right Rear Upright is manufactured to tighten cornering behaviour on race circuits. It delivers 1 degree of outboard toe-in to stabilise the rear during corner entry and safeguard suspension geometry under heavy load or impacts. The medium flex characteristic is focused on performance with rubber-tyre setups for consistent traction.

Key tuning features

You get two selectable roll centre positions to tailor handling for different grip levels and driving styles. The compact 5x10 ball bearings reduce unsprung mass for crisper steering and faster reactions. This upright remains suitable for both rubber and foam tyre choices depending on your setup preference.

Compatibility notes and setup tips

This right-side upright is intended to work in tandem with the matching left upright (303361) to keep balance across the rear. For best performance, pair it with the recommended rear hardware and tweak toe and roll centre to suit whether you run rubber or foam tyres.
