Rear Upright Assembly (Excluding Axles, bearings, nuts & retention system)

In Simple Terms

The rear upright assembly is the structural component that connects the suspension to the rear wheel hub. It includes the upright itself, any brackets used for setup adjustments, fasteners, and electrical components—but excludes the actual axles, bearings, and nuts that hold it together. This regulation defines what parts are considered part of the upright for technical compliance purposes.

• Covers the upright structure between suspension connection points and wheel bearings
• Includes setup variant brackets that teams use to adjust car handling
• Encompasses fasteners and any local electrical/electronic components attached to the upright
• Excludes axles, bearings, nuts, and retention systems (covered separately)
