Adjust gearbox height on YZ-4SF

This aftermarket accessory is an RC-scale gearbox height adapter made to work with YZ-4SF standard parts and B-YZ4SF chassis layouts. It mounts to both ends of the gearbox on the bulkhead to change the gearbox vertical position without modifying the chassis or gearbox shell.

By raising or lowering the gearbox, the adapter changes the angle between the universal shaft and the suspension arm / upper arm. Those angle changes let you fine-tune traction and turn-in response through drivetrain geometry rather than by altering spring rates or damping.

Installation is straightforward on compatible bulkheads: the adapter is fitted at each gearbox end and secured in the mounting points provided on the bulkhead, keeping the unit entirely within RC-scale components and routine maintenance procedures.

Remark :

Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does changing gearbox height affect handling?

Altering the gearbox height shifts the universal shaft angle relative to the suspension arms, which changes traction balance and steering feel. Small adjustments can noticeably affect turn-in and mid-corner grip without touching suspension valving.

Can I tune traction without changing springs or shocks?

Yes. By changing drivetrain geometry with this adapter you can influence traction and steering characteristics independently of spring and damper setup, making it a useful tuning lever.
