Tamiya 53721 TB Evo IV Aluminum One-Way Ring Gear - Track Ready Upgrade  [53721]

Track-Ready Aluminium Upgrade for the TB Evo IV

For competitive club racers and weekend tuners, the Tamiya 53721 Aluminum One-Way Ring Gear is a solid step up from plastic rings, delivering firmer power transfer and less slippage under load. The aluminium construction helps protect other drivetrain parts by resisting wear and keeping engagement consistent.

Performance Advantages of Metal Gears

Metal ring gears offer better structural integrity under repeated stress, meaning you will replace parts less often and spend more time tuning. The Tamiya 53721 has tight tolerances to pair smoothly with the TB Evo IV layout, promoting efficient drivetrain operation.

Fitting Checklist for Best Results

Ensure all mating components are free of grit before installing the Tamiya 53721 Aluminum One-Way Ring Gear, and use the right gear grease to reduce friction. Confirm proper gear mesh and rotate the assembly by hand to check for any binding or unusual noises before running.
