Yokomo S4-500MG3A performance diff kit for YZ-4SF

The Yokomo S4-500MG3A metal gear differential kit is a targeted performance upgrade for the YZ-4SF chassis. Metal gears provide longevity while resin cross pins shave weight from the rotating assembly, balancing durability and agility. A practical option for riders who tune for grip and reliability.

Specifications

  • Material: Metal Gears with Resin Cross Pins
  • Compatibility: YZ-4SF Chassis
  • Additional Parts Required: Ring Gear (S4-503R16, etc.)

This metal diff kit is suited to YZ-4SF drivers looking to extend gear life and reduce rotating mass without changing major drivetrain geometry.
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.

Can I use my existing ring gear?

You can reuse the original ring gear only if it matches the diff tooth count and mounting. Otherwise, fit a recommended ring gear like the S4-503R16.

Will this change handling on hardpack tracks?

Reducing rotating weight with resin pins can sharpen initial response; pairing the diff with the right oil helps fine tune handling for hardpack surfaces.

Are spare cross pins available separately?

Spare resin cross pins are commonly available from parts suppliers. Keep spares on hand if you race regularly or run rough terrain.
