Tamiya 53721 TB Evo IV Aluminium One-Way Ring Gear - Precision Fit Upgrade  [53721]

Precision Aluminium Ring Gear for TB Evo IV

If you run a TB Evolution IV and want crisper gear engagement, the Tamiya 53721 Aluminum One-Way Ring Gear replaces stock plastic components to sharpen power transfer and lower the chance of slippage. The machined aluminium construction is chosen for consistent strength and improved wear resistance over long sessions.

Why Aluminium Works Better in the Drivetrain

Compared with plastic, aluminium handles torque and heat far better, which reduces deformation and extends service intervals. The Tamiya 53721 is engineered to align with TB Evo IV drive parts, giving a smooth mesh and dependable running characteristics for club racing or practice days.

Simple Fitment Hints

Keep all parts clean before assembly and apply the correct grease to engage points. When installing the Tamiya 53721 Aluminum One-Way Ring Gear, check backlash and tooth contact to avoid premature wear and to keep noise to a minimum.
