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.

Does this part improve reliability on race day?

It improves gear engagement and reduces the chance of slop in the drivetrain, which aids consistent performance, though overall results depend on setup and upkeep.

Is any special tooling required to fit the diff case?

Standard hobby tools are sufficient for installation; use a torque driver for repeatable screw settings and check mesh with a feeler or shim method.

How often should I inspect the pulley and gears?

Inspect after a few running sessions for debris and wear, and recheck gear mesh and pulley runout as part of routine maintenance to avoid failures.
