Reliable Aluminium Ring Gear for TB Evo IV

Owners of the TB Evolution IV can upgrade the standard plastic ring with the Tamiya 53721 Aluminum One-Way Ring Gear to gain steadier power transfer and lower the chance of slip under strain. The aluminium build increases resistance to wear and keeps drivetrain behaviour more predictable during repeated use.

Why Switch to an Aluminium Ring Gear

Aluminium tolerates higher torque and maintains shape better than plastic, resulting in extended part life and fewer unscheduled swaps. The Tamiya 53721 is manufactured to fit the TB Evo IV configuration, enabling a straightforward upgrade for experienced builders and racers.

Tips for Correct Installation

Before fitting the Tamiya 53721 Aluminum One-Way Ring Gear, make sure mating surfaces are clean and free of debris. Use a light metal-compatible grease, set the tooth mesh carefully and spin the drive by hand to confirm smooth, quiet operation.

Will this improve longevity compared with the plastic ring?

Yes, aluminium generally resists wear better than plastic, so you should see longer service life when the part is correctly installed and maintained.

Is any break-in required after fitting?

Run the car at low speed initially to confirm correct mesh and lubrication; this helps seat the gear without placing excessive loads on fresh contact faces.

Can I use this part for off-road running?

It can be used off-road, but clear away dirt and grit after each session and re-lubricate more frequently to avoid abrasive wear.

Any routine checks to keep it performing well?

Regularly inspect the teeth for nicks, check bearing play and confirm the gear remains securely mounted to prevent premature failure.
