Aftermarket 7075 aluminium transmission housing for PROMOTO-MX

This CNC-machined 7075 aluminium housing is an aftermarket replacement tailored for LOSI PROMOTO-MX motorcycles. It gives a firmer mounting surface for drivetrain parts on the listed PROMOTO-MX RTR and PRO CIRCUIT variants, helping improve longevity and alignment under load while keeping the original fit geometry.

Designed for use with existing stock mounting positions and hardware, the housing provides mechanical protection and positional control for gearbox assemblies and related drivetrain components without changing gear ratios or electronic function.

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

Use MX038 when you want a metal direct-fit housing to keep drivetrain components aligned and to simplify service; retain or verify original bearings and fasteners and check clearances before first use.

Is this housing a direct replacement for stock parts?

Yes, MX038 follows the stock geometry for the listed PROMOTO-MX RTR and PRO CIRCUIT items and installs using the existing mounting locations on those chassis.

What is supplied in the MX038 kit?

The kit includes a three-piece transmission housing set and one 5x13x4 bearing, provided to match the original part reference for easy swap-in.

Will this change my gear mesh or ratios?

No, the housing is intended to protect and stabilise the drivetrain; it does not alter gear ratios or change electronic behaviour, though it can make gear mesh more consistent under load.

Do I need special tools to fit it?

Installation usually requires standard hand tools for removing the stock housing and refitting the parts; ensure threads and bearing seats are clean and in good condition before reassembly.

How should I check clearances after installing?

Spin the gearbox by hand to confirm free rotation, check for contact points, and verify the supplied 5x13x4 bearing seats correctly; adjust as needed before the first powered run.
