Tamiya 49378 - TRF415MSX Performance Upgrade  [49378]

Performance Upgrade for Tamiya 49378 - TRF415MSX Chassis

Racers seeking a more planted TRF415MS will find the Tamiya 49378 - TRF415MSX Hop-Up Conversion Kit a practical upgrade. It focuses on delivering steadier handling and easier setup changes between sessions.

Lowered Centre of Gravity for Stable Handling

The conversion adjusts the TRF415MS layout to bring components closer to the chassis plane, improving cornering stability. Bulkheads are made for quick removal so drivetrain servicing is faster. The longer rear bulkhead helps centralise mass while the shortened upper deck threads between the drive belt to tie the front and rear bulkheads together for better weight distribution.

Durable Layout with Simplified Servicing

By removing the middle deck the upper arm mounts directly to the bulkhead, increasing the suspension's resistance to flex and reducing wear under high lateral force. This construction keeps geometry consistent under load. The box included with the kit doubles as a battery case and stores up to 11 6-cell batteries for tidy transport and pit organisation.
