WR8 / Bullet 3.0 Precision Alloy Gear Box BMT012 by GPM  [BMT012]

Precision alloy gearbox housings for service use

This alloy front and rear gear box set is a direct-fit RC-scale replacement intended for HPI Bullet 3.0 MT and ST nitro platforms. It is supplied as a single set and matches the service role of replacing worn or damaged gearbox modules on compatible WR8 and Bullet 3.0 chassis.

The design focuses on accurate mechanical interfaces to preserve original mounting geometry and enable reuse of spur gear, pinion and fastening hardware where compatible. Follow standard disassembly and reassembly procedures, confirm gear mesh and alignment on installation, and verify free driveline rotation before powering the model.

Intended for maintenance and repair, this alloy housing set provides a replaceable casing for drivetrain inspections. Internal bearings and gearing are not guaranteed to be included, so check the supplier listing for exact contents before starting work.

Keep this alloy gearbox housing set for workshop replacements or inventory support when servicing WR8 and Bullet 3.0 nitro projects, and confirm included parts on receipt to ensure proper fitment.
