XRAY 333311-H Hard Composite Rear Upright Aero Disc Ready  [XR-333311-H]

Stability boost with XRAY 333311-H rear uprights

The XRAY 333311-H hard composite rear uprights are built specifically for the NT1 2023 chassis, giving club racers a stronger rear end without excess weight. Made from a tailored composite, these uprights balance toughness and lightness to help maintain competitive lap times.

Accurate bearing fit and durable molding

Each upright is precision molded to hold bearings securely, removing play that can upset handling at speed. The tight tolerances help keep suspension geometry consistent lap after lap.

Tuneable roll-center options

Dual mounting points for the upper roll-center linkage let you alter roll-center height to match different tracks and driving styles. Small changes here can noticeably change mid-corner balance.

Supports optional graphite Aero discs

These uprights accept optional graphite Aero discs to increase rear stability and traction on smooth surfaces. Fit them when you need added control for high speed sections.
