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

Mid-Chassis Bulkhead Upgrade for Bullet Flux

The BUL-18006-GU is a gunmetal alloy center bulkhead made for HPI Bullet Flux chassis, supplied complete with a bearing to stabilise the drivetrain and cut central flex under race and tuning loads.

Its metal construction gives a firmer mounting compared with stock plastic bulkheads, helping hold gear mesh and minimise mid-chassis movement when testing suspension setups or changing pinion and spur gears. The included bearing reduces rotational play at the driveshaft interface so driveline response remains consistent under load.

Installation requires partial disassembly of the centre chassis area to replace the OEM bulkhead. Careful alignment during reassembly prevents unwanted preload on the bearing and preserves correct driveline angles. This is an RC accessory intended for model-level tuning and not for any full-size applications.

Use this center bulkhead to stiffen the chassis center and reduce driveline play for tuned or competitive HPI Bullet Flux setups.
