CNC machined 7075 transmission housing for PROMOTO-MX

This 7075 aluminium transmission housing is a precision aftermarket replacement intended for LOSI Promoto-MX motorcycles. Machined from 7075 aluminium as stated in the source, the housing replaces the factory plastic shell on the listed Promoto-MX models to increase structural stiffness and improve long-term drivetrain durability under competitive or heavy-load use.

The assembly ships with a single 5x13x4 bearing to align with the supplied mounting interfaces. As an aftermarket part it installs using the motorcycle's existing fasteners and drivetrain components; during installation verify bearing seating and shaft alignment to prevent axial preload or lateral misalignment affecting spur and pinion engagement.

From an upgrade perspective this component reduces gearbox flex, offers improved resistance to impact and wear, and preserves the original service access layout for routine maintenance and tuning work.

Packing includes

  • Transmission housing (1 set of 2 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

For experienced builders and technicians, this GPM 7075 housing provides a precise, durable gearbox solution for PROMOTO-MX platforms; always confirm fitment and bearing seating during assembly to ensure optimal drivetrain alignment.

Does the housing maintain OEM mounting geometry?

Yes, the housing is machined to align with the original mounting interfaces for listed Promoto-MX models, allowing use of the stock fasteners and components.

What are the bearing requirements and preload checks?

The unit ships with a 5x13x4 bearing; during assembly ensure the bearing is fully seated and check for correct endplay to avoid axial preload that can bind the gear train.

How does 7075 aluminium benefit high-stress setups?

7075 aluminium provides superior stiffness and fatigue resistance compared with standard plastics, improving mesh stability under higher torque and reducing deformation-related wear.

Are there specific torque values recommended for reassembly?

Follow the motorcycle's original fastener torque guidelines where available; tighten progressively and recheck gear mesh and bearing seating to ensure no preload is introduced.
