• Supports #35 chain 12T or #40/41/420 chain 10T setups for flexible sprocket and chain matching.


• Reduces vibration with a dynamically balanced axle to help improve smoothness and component life.


• Includes installation accessories to streamline replacement or new-build drivetrain assembly.

Designed for builders who want reliable direction changes without complicated controls, this forward/reverse clutch gearbox kit combines durable iron and aluminum alloy parts with practical ratios for trail and yard use. The compact size makes it easier to integrate into many small off-road frames, while the heat-dissipating metal body helps handle frequent shifting and stop-and-go driving.
