Gunmetal Centre Bulkhead for Bullet Flux Racing

The BUL-18006-GU centre bulkhead is a gunmetal alloy replacement part for HPI Bullet Flux models, delivered with an integrated bearing to support the driveshaft and reduce mid-chassis movement during demanding use.

Replacing the standard plastic bulkhead with this alloy version gives a more rigid mounting for gearbox components, helping to protect gear engagement when you run stiffer suspension or higher torque setups. The bearing reduces rotational slop for a firmer driveline feel.

Installation involves removing the centre section to swap the original bulkhead; ensure correct alignment on reassembly to prevent bearing preload and unwanted driveline angles. This item is intended purely for scale RC tuning and competition, not for real vehicles.

Specifications

  • Item: Center bulkhead set with bearing
  • Material: Gunmetal alloy
  • Model Number: BUL-18006-GU
  • Compatibility: HPI Bullet Flux

Choose this centre bulkhead when you need a tougher central mounting point to keep driveline alignment under high loads on HPI Bullet Flux rigs.

Is the gunmetal part better for off-road use?

Gunmetal alloy offers higher stiffness than plastic and can withstand heavier loads, which benefits off-road or aggressive driving where chassis flex can affect gear engagement.

Does it require changes to gearbox setup?

Most installs are direct replacements, but you should verify gear mesh and driveline angles after fitting; small adjustments can be needed to optimise contact patterns.

What benefit does the bearing provide?

The bearing reduces play at the driveshaft interface, improving rotation consistency and reducing the chances of transient lash under load during tuning or racing.

How to inspect the bulkhead after heavy use?

After heavy sessions, check mounting screws for tightness, inspect the bulkhead for deformation, and spin the bearing to confirm smooth operation; replace parts showing wear.
