Rear Left Upright and Hub

The rear left upright is a billet aluminum structural component that connects the upper and lower A-arms and toe link to the wheel hub, forming the cornerstone of the rear left corner's suspension geometry. It provides the mounting points for camber and toe adjustment, allowing the rear suspension to be dialed in to the recommended baseline or tuned for specific track conditions.

This listing includes the upright paired with the wheel bearing hub assembly — a sealed unit that mounts directly to the upright face. The sealed bearing requires no preload adjustment or routine maintenance beyond annual inspection. If you detect play, noise, or roughness at the wheel, the hub assembly should be replaced as a complete unit rather than serviced.

This is an OEM replacement part — the same component installed on every Rush SR at the factory. It is side-specific: this is the rear left only. A matching rear right upright and hub is available separately.
