High Precision Ball Differential for YD-2

Fit the Yokomo Y2-500AA to your YD-2 setup to reduce unsprung rotating weight and refine throttle input. The aluminium construction combines toughness with a lighter footprint, helping deliver more consistent handling through corners.

Featherweight Design Improves Control

The Yokomo Y2-500AA uses aluminium differential cases to cut down mass so the car reacts faster to throttle changes and exhibits less gyroscopic drag. The intrinsic traction behaviour of the ball differential is preserved, giving drivers predictable slides and exits.

Resin Tip Guard for Cleaner Operation

A resin protector sits at the dogbone tip of the universal, limiting abrasion against the aluminium and keeping clearance consistent. This small detail helps the Yokomo Y2-500AA resist wear and keep performance stable over many runs.
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 the kit need modification for longer axles?

Most YD-2 standard axles work without changes, but if you run non-standard shaft lengths or extended setups, verify clearance and spline engagement before final assembly.

What grease or oil is recommended for the ball diff?

Use a consistent diff grease suited to your driving style; thicker compounds increase lock while lighter ones free up movement. Tune oil choice to track conditions and power delivery.

Is this a good choice for street drifting or carpet?

Yes, the lighter housing and preserved ball diff feel make the Yokomo Y2-500AA adaptable to both smooth indoor surfaces and controlled outdoor sliding, depending on setup and tyre choice.
