The 3Racing SAK-MG37 aluminium spur gear adaptor is a precision upgrade for Sakura Mini MG vehicles using the KIT-D4 or KIT-MINI MG platforms. It provides a firmer motor-spur interface to reduce drivetrain play and support steadier power delivery.
The adaptor is manufactured to match the Sakura Mini MG mounting geometry for a tidy installation. During fitting check gear mesh and motor offset to ensure the aluminium adaptor seats squarely and preserves correct spur engagement.
Competitors favour the SAK-MG37 because it reduces movement in the drivetrain under load, which keeps handling predictable and reduces wear on spurs and pinions over extended runs.
