Tamiya 15374 JR Lightweight Center Chassis - Mini 4WD PRO performance chassis  [15374]

Product snapshot

The Tamiya 15374 JR Lightweight Center Chassis is aimed at racers who prioritise a lighter platform for Mini 4WD PRO models. Constructed from reliable ABS resin, it cuts weight by around 10 percent relative to a standard MS chassis while keeping structural integrity. The form factor enhances air circulation to support steady motor performance.

Operational features and cooling

A new turn switch arrangement for the switch lever improves usability during events. The chassis layout also encourages improved airflow across the motor area to help reduce thermal build up on long runs.

Performance tuning and parts fitment

This centre chassis accepts a variety of Mini 4WD PRO upgrades including reinforced gear covers and alternative mounting options. Builders often fit it with high output motors, tuned gearing and choice tyre setups to dial in top speed or cornering balance.
