Rear Right Upright base assembly

The rear right upright base assembly is the OEM billet aluminum upright that mounts at the right rear corner of the Rush SR chassis. It serves as the central hub carrier for that corner, providing mounting points for the wheel bearing hub, lower and upper A-arms, toe link, and shock absorber.

Uprights on the Rush SR are machined from billet aluminum and include provisions for adjustable camber and toe settings. The base assembly refers to the upright body itself — the foundation to which ball joint pins, spacers, and the wheel bearing hub assembly attach. When replacing this component, the hub, ball joints, and associated hardware are installed separately.

This is the right-side rear upright. A matching left-side version is available for the opposite corner.
