Rear Upright

The rear upright is the billet aluminum hub carrier at each rear corner of the Rush SR's double wishbone suspension. It serves as the central structural node connecting the upper A-arm, lower A-arm, and toe link, while also providing the mounting face for the wheel bearing hub assembly. Camber is adjusted via shim plates at the ball joint mounting points, and toe is dialed in through the rear toe link.

This is an OEM replacement part — the same billet aluminum upright that comes standard on the Rush SR. Sold individually (one per side). Related components include ball joint pins, ball joint spacers, the wheel bearing hub assembly, and rear toe links. Note that the Wide Rear Camber Plates, required for 2026+ competition use, are a separate item.
