TRF 416 Outer Axle Join for TAMIYA Solid Axle 416-12A by 3Racing  [416-12A]

Precision outer axle join for TRF 416

This replacement outer join is specified for the TAMIYA TRF 416 chassis and is identified as part 416-12A. It provides the external coupling between the solid axle and the wheel hub assembly to maintain drivetrain alignment and control lateral play at the hub.

Manufactured to match the TRF 416 axle interface, the unit is intended as a direct outer-end swap that preserves central drivetrain geometry. Installation requires hub removal, inspection and cleaning of mating surfaces, correct seating with orientation checks, and verification of fastener preload to factory or tuned settings.

In a tuning environment the outer join restores consistent torque transfer and predictable handling after wear or impacts, aiding competitive setup work such as end-play adjustment, spur and pinion engagement tuning, and suspension geometry verification.
