XRAY 363353 Composite Rear Upright - Tunable Rear Hub for RC Performance  [XR-363353]

Stable, Tunable Rear Upright by XRAY 363353

The XRAY 363353 Composite Rear Upright is built to improve handling and resilience in competitive RC setups. Molded from a tough composite, it provides two roll center choices and is shaped to fit left and right sides without adding unnecessary bulk. The compact layout keeps strength where you need it, protecting suspension geometry under hard landings.

Tuning Options and Geometry

This upright features a fixed lower roll center setting together with three selectable upper roll center positions for precise handling adjustments. The 0 degree toe configuration helps keep track stability and predictable steering response when the car is pushed hard.

Bearing Layout and Weight Considerations

For reliable performance the XRAY 363353 uses larger 5x12 outer ball bearings to handle dynamic loads, while smaller 5x10 bearings occupy the inner position to reduce unsprung mass and keep spinning parts light.
