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.

Will this fit other Yokomo diffs?

The S4-500MG3A is engineered specifically for the YZ-4SF. Some parts may be compatible with other models but fit is not guaranteed without modification.

Do I need a ring gear to install it?

Yes, you should fit a matching ring gear such as the S4-503R16 to complete the installation if your current ring gear does not match.

How should I maintain the resin cross pins?

Inspect the cross pins regularly for wear and keep the diff lubricated with the recommended oil. Replace pins if you notice any cracking or deformation after heavy use.
