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.

Is the S4-500MG3A hard to fit?

Installation is straightforward for anyone familiar with YZ-4SF maintenance. Basic tools are needed and a compatible ring gear must be used.

What gear oil should I use inside this diff?

Use a diff oil suited to your driving style. Lighter oil helps for quick transient response while heavier oil improves traction and stability.

Will the resin cross pins break easily?

Resin cross pins reduce weight but check them after hard impacts. They are durable in normal use but should be inspected regularly.
