GPM Racing Steel Ring Gear - 1pcs (For Tt02/Tt02b) for Tamiya TT02 (TT2100/G1)

Precision-engineered steel ring for TT02 series

This aftermarket steel ring gear is supplied as a direct-fit replacement for Tamiya TT02 and TT02B platforms, provided as 1 pcs for drivetrain maintenance or upgrade. The hardened steel construction aims to extend service life compared to standard plastic rings while preserving the stock mounting and alignment characteristics.

Installation is intended to maintain the factory gear mesh and centreline, so changeover typically requires standard gearbox access and a careful pinion-to-spur mesh check. Follow professional setup practice: confirm correct engagement, verify free rotation, and re-check mesh after a controlled break-in interval.

Performance note: upgrading to steel reduces plastic wear under increased loads but alters load distribution across the drivetrain; evaluate pinion and bearing condition and consider reinforcement where necessary for sustained high-load operation.

Compatible Models

• TT02
• TT02B

Does the gear match OEM mounting and tooth count?

Yes, the component is manufactured to fit the standard TT02/TT02B mounting pattern and tooth profile; verify mesh during assembly for optimal contact.

What should I inspect after fitting a steel ring?

Inspect pinion tooth condition, bearing play, and gearbox shaft alignment after initial runs to ensure the drivetrain is coping with the increased tooth stiffness.

Is this intended for competition tuning?

It is well suited to tuning and higher-load scenarios where plastic wear is a limitation; assess the surrounding drivetrain hardware for compatibility when used in competitive setups. Write Product Review Please sign in your account before you can write any review. Sign In Close
