Zero Cero Graphite Rear Bulkhead Pair - O-3CP015 by 3Racing  [FP-O-3CP015]

Stiff graphite rear bulkheads for Zero Cero

This Factory Pro O-3CP015 bulkhead plate is an RC-scale replacement part produced for 3Racing Zero Cero chassis, supplied as a matching pair (2 pcs). The plate is made in graphite to keep stiffness high while minimising added weight, and is intended to directly substitute the stock rear bulkheads without chassis modification.

Fit and function are focused on chassis alignment and drivetrain support. As a direct-fit hop-up, it locates bearings and gearbox mounts in the same positions as the original parts so you can retain existing spacers and screws. Use it when you need to restore rigid mounting points after wear or to slightly reduce flex for more consistent drivetrain behaviour.

Installation is straightforward on the Zero Cero: remove the original bulkheads, transfer any bearings or inserts, and secure the graphite plates with the original hex screws. Check bearing preload and gear mesh after installation, and confirm clearance around the motor and wave washer if the build uses aftermarket pinion or spur sizes.
