Precision metal differential Yokomo S4-500MG3A for YZ-4SF

The Yokomo S4-500MG3A metal gear differential kit is crafted for the YZ-4SF chassis to improve robustness and lower rotating mass. Metal gears increase service life while resin cross pins offer weight savings without compromising core strength. A neat upgrade for those refining drivetrain performance.

Specifications

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

Fit this metal gear diff kit to achieve a balance of longevity and reduced inertia in the YZ-4SF drivetrain, helping with consistent lap times and maintenance intervals.
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 replace the standard YZ-4SF diff?

Yes, the S4-500MG3A is a direct upgrade intended to replace the stock centre differential in the YZ-4SF, subject to fitting the correct ring gear if needed.

How long does installation typically take?

A routine installation by an experienced hobbyist takes around 20 to 40 minutes, including checking gear mesh and adding the appropriate diff oil.

Which ring gear should I order?

Use a compatible ring gear such as the S4-503R16 or a part specified for the YZ-4SF to ensure correct fit and tooth engagement.
