This GPM MJ1555T set supplies an aluminium spur gear adapter paired with a 55T steel spur gear designed for AXIAL SMT10 applications. The kit is intended as an RC-scale replacement part for drivetrain assemblies where a durable steel spur and a light alloy adapter are required to interface with existing motor pinion and gearbox layouts.
The package includes the small fasteners and collars needed to mount the adapter and gear to the existing assembly. Installation typically replaces the stock plastic adapter and spur, retaining the vehicle's original mounting points and shaft spacing.
In tuning terms this part is a component-level upgrade: the steel 55T spur resists wear under higher torque loads, while the aluminium adapter keeps weight down and provides a rigid, concentric interface. Check alignment and mesh with the motor pinion before final assembly, and verify clearances with the gearbox and suspension travel to avoid interference.
Use this set when replacing worn stock spur components or when seeking a tougher steel gear paired to a lightweight alloy adapter for consistent mesh and improved wear resistance in AXIAL SMT10 based models.
