MX038 CNC transmission housing for PROMOTO-MX

This CNC-machined 7075 aluminium transmission housing is manufactured as a precision aftermarket replacement for LOSI PROMOTO-MX motorcycles. The component is machined to tight tolerances to provide a rigid, durable mounting surface for gearbox and drivetrain parts on the specified PROMOTO-MX RTR and PRO CIRCUIT models, while preserving original mounting geometry for direct-fit installation.

Designed for use with the stock mounting points and fasteners where applicable, the housing serves to protect mechanical components and maintain positional stability of the gearbox and related drivetrain elements. It is not intended to modify gear ratios or electronic behaviour; installers should inspect bearing seats and mating surfaces during assembly to confirm correct alignment and clearance.

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 a precision aluminium housing is required to increase drivetrain stiffness and simplify maintenance cycles; verify bearing seating and fastener condition during fitment to ensure optimum alignment and load transfer.

Is MX038 compatible with the listed PROMOTO-MX models?

MX038 is produced to match the original mounting geometry for the models shown in the compatibility box and is intended as a direct-fit replacement when correct hardware and bearings are used.

What is included and what is the reference number?

The package comprises a three-piece transmission housing set and one 5x13x4 bearing, with the original cross-reference part number LOS262008 for verification.

Are there any fitment checks recommended for installation?

Inspect the bearing seats, mating surfaces and fastener threads before assembly. Ensure the supplied 5x13x4 bearing seats squarely and that torque settings are correct to preserve alignment under load.

What performance benefits does the 7075 housing provide?

7075 aluminium offers high stiffness and fatigue resistance, improving gearbox positional stability and reducing component movement under stress, which supports consistent gear mesh during tuning and running.

Should other parts be upgraded alongside this housing?

Consider inspecting and, if necessary, replacing worn bearings and fasteners to ensure the full benefit of the MX038 housing is realised; matching quality bearings and correct torque settings maintain alignment and load distribution.
