Tamiya 3451516 Heavy Duty Center Pulley 20T for TRF421  [3451516]

Refine Power Delivery with the Tamiya 3451516 Pulley

The Tamiya 3451516 Center Pulley is a purpose made component for the TRF421 chassis, offering a 20-tooth configuration that promotes consistent drivetrain action. It is a practical upgrade for racers and hobbyists aiming to reduce drivetrain wear and maintain steady acceleration.

Better Gear Engagement

The 20T design encourages even engagement across the gear train, lowering shock loads and helping gears run cleaner. That improved engagement supports repeatable lap times and reduced component replacement.

Made for the TRF421 Chassis

Built to match the TRF421 mounting and spacing, this pulley installs without extra machining. It is intended to drop into the original setup for a hassle free replacement or upgrade.

Durable Construction

Manufactured from high quality materials, the pulley copes well with extended use and the occasional hard hit. Durability here means fewer service intervals and reliable track performance.
