HPI Bullet Flux Gunmetal Alloy Center Bulkhead Set w/Bearing by JAZRIDER BUL-18006-GU  [BUL-18006-GU]

Center Bulkhead Set for Bullet Flux

The JAZRIDER BUL-18006-GU is an RC-scale center bulkhead set designed for HPI Bullet Flux models, supplied as a gunmetal alloy assembly that includes a bearing. Its role is purely for model drivetrain structure and alignment, intended to reduce flex at the chassis center and keep gearbox and drive components tracking correctly.

Constructed from a gunmetal alloy, the part provides a firmer mounting point compared with stock plastic bulkheads, which can help preserve gear mesh and reduce mid-chassis movement when tuning suspension or experimenting with different pinion and spur setups. The included bearing supports the driveshaft interface to lower rotational play and maintain consistent driveline behaviour under load.

Installation notes: the component sits at the vehicle centerline replacing the OEM center bulkhead, and requires partial chassis disassembly to access the gearbox area. Alignment during reassembly matters for driveline angles and to avoid preload on the bearing. This is an RC accessory part intended for model-level adjustments and tuning, not for any full-size applications.

Use this center bulkhead when you need a stiffer central mounting point and reduced driveline play for tuning or competitive RC use on HPI Bullet Flux chassis.
