Zero Cero Rear Graphite Bulkhead Plates for Direct Fit - O-3CP015 by 3Racing  [FP-O-3CP015]

Zero Cero graphite rear bulkhead replacement

This Factory Pro O-3CP015 bulkhead plate is an RC-scale replacement part made for the 3Racing Zero Cero chassis and shipped as two matching plates. The graphite construction preserves stiffness while keeping additional mass to a minimum, allowing direct substitution of the stock rear bulkheads without any chassis modifications.

Designed for simple fit and drivetrain support, the plates retain original bearing and gearbox mount positions so existing spacers and fasteners remain compatible. Fit these when worn stock mounts compromise alignment or when a small reduction in chassis flex is desired for steadier drivetrain response.

Fitting is straightforward: remove the OEM bulkheads, move over bearings or inserts, and fasten the graphite plates with the original hex screws. After installing, recheck bearing preload and the pinion-to-spur mesh, and ensure there is adequate clearance near the motor and wave washer with any aftermarket pinion or spur sizes.
