XRAY 363353 Composite Rear Upright - Compact Rear End Upgrade  [XR-363353]

Reliable Rear Upright from XRAY 363353

The XRAY 363353 Composite Rear Upright is designed for hobbyists who want dependable handling without sacrificing toughness. Made from a reinforced composite, it gives you two roll centre choices and fits both sides of the rear suspension. Its compact form keeps the assembly tight while resisting impact damage.

Geometry Choices for Better Handling

This part provides a fixed lower roll centre plus three selectable upper roll centre positions so you can fine tune balance and roll behaviour. A neutral 0 degree toe setting helps maintain straight line stability and consistent suspension geometry under load.

Bearing Selection and Performance

The bearing arrangement uses 5x12 ball bearings in the outer hole to improve dynamic load support, while 5x10 bearings are used internally to trim unsprung weight and aid acceleration.
