7075 aluminum transmission housing for PROMOTO-MX

This CNC-style 7075 aluminum transmission housing is a direct-fit replacement for LOSI PROMOTO-MX motorcycles. Machined to provide a firmer mounting surface, the part improves durability and positional stability for drivetrain components on the listed PROMOTO-MX RTR and PRO CIRCUIT models while keeping original geometry for straightforward swapping during maintenance or tuning.

Installation uses the stock mounting points and fasteners where applicable; the housing is intended to protect and stabilise gearbox assemblies and related drivetrain items rather than change gear ratios or electronic settings. Inspect bearings and mating surfaces when you install the unit to ensure correct clearances.

Packing includes

  • Transmission housing set (1 set of 3 pieces) - 1pcs
  • Bearing 5x13x4 - 1pcs

Original Name / Part No:

LOS262008

Compatible Models

  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR
  • FXR-LOS06000
  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR PRO CIRCUIT-LOS06002

Choose this MX038 7075 housing when you require a metal direct-fit replacement to maintain drivetrain alignment and simplify service intervals; keep the original bearing sizes and fasteners and verify clearance before the first run.

Does MX038 fit the PROMOTO-MX RTR without modification?

MX038 follows the OEM mounting geometry for the listed PROMOTO-MX RTR and PRO CIRCUIT items, so it fits as a direct replacement on those chassis. Double-check fastener fit and bearing seats during installation.

What parts come in the package?

The kit contains the transmission housing set (three-piece set) and one 5x13x4 bearing, matching the original reference for straightforward replacement.

Will I need new fasteners or bearings when fitting this housing?

In most installs the stock fasteners and bearings can be reused, but inspect the bearing seat and threads; replace any worn items to preserve alignment and load distribution.

How does the 7075 construction change drivetrain behaviour?

The 7075 alloy adds stiffness and impact resistance to the housing, which helps maintain consistent gear mesh under load and gives clearer feedback when tuning suspension and drivetrain setups.

Is the supplied bearing the correct type?

The package includes a 5x13x4 bearing; verify this size against your current parts before fitting to ensure correct fitment and function.
