3Racing M4WD-38/BL shaft stopper for Mini 4WD use

The 3Racing M4WD-38/BL is an aluminum shaft stopper intended as a direct replacement for common plastic retainers on Tamiya Mini 4WD models. Its black anodized finish and machined profile are focused on fit and durability rather than altering drivetrain geometry.

Where collectors and builders commonly swap worn plastic parts, this stopper offers a metal option that resists wear from repeated maintenance. The part is presented as a single collar-style stopper; installation generally follows the same mounting approach as the original plastic piece.

In practical use, the stopper serves to limit axial play of wheel or gear shafts and to provide a consistent seating surface for bearings or bushings used on performance chassis. It is appropriate for routine replacements, restoration of older models, or when a more durable stop surface is preferred during repeated assembly and disassembly.

Handle installation with standard hobby tools and avoid over-torquing fasteners to prevent distortion of mating parts. The part does not change gear ratios, motor specifications, or basic drivetrain layout; keep standard setup practices for the chassis in use.
