Willspeed 3 Gear Aluminium Gearbox - Team Associated RC10B7 - (W3125)

The Willspeed B7 3 Gear Aluminium Gearbox is a premium transmission upgrade for the Team Associated RC10B7 and B7.1, designed for racers who prefer the characteristics of a traditional 3-gear transmission layout.

By moving the motor position 11mm rearwards, this gearbox provides an alternative weight distribution option compared to the standard transmission, allowing drivers to fine-tune vehicle balance and handling for different track conditions.

Precision machined from 6082 aluminium and finished in black anodising, the gearbox includes Willspeed's signature 36T PEEK idler gear. Manufactured from a high-performance engineering polymer, the PEEK gear delivers excellent wear resistance, smooth operation and long-term reliability while remaining exceptionally quiet and efficient.
