Precision Cooling Upgrade for YZ-2 and YD-2 Chassis

The Yokomo Z2-503GHCA aluminum gear differential case cap is tailored for YZ-2 off-road and YD-2 drift platforms. Its metal construction moves heat away from the diff faster than resin, reducing oil temperature swings and maintaining steady handling through longer sessions.

Advantages of Metal Over Resin

Aluminum delivers superior heat spread and tighter tolerances, which lowers the risk of oil breakdown and improves rotational efficiency. This can help avoid premature wear and keep diff behavior predictable lap after lap.

Perfect for Track Tuning

Drivers focused on consistent lap times will appreciate the more stable diff response enabled by this cap, which supports finer setup adjustments and repeatable results.

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.

How straightforward is the installation on a YZ-2 or YD-2?

Installation is simple and follows the existing screw pattern; it replaces the stock cap without modifying the chassis or internal components.

Will I notice immediate temperature changes after fitting this cap?

Yes, aluminium conducts heat more efficiently, so you should see improved heat dispersion in short runs and more consistent oil viscosity across use.
