Save weight and boost response on the YD-2 with Yokomo Y2-501MRA

The Yokomo Y2-501MRA Aluminium Ball Differential Joint Set is a direct upgrade for YD-2 cars, engineered to cut rotating weight while holding up under aggressive track use. These aluminium joints swap in for the stock gear differential to give a more immediate feel to steering and throttle transitions.

Aluminium advantages for fast running

Aluminium combines low mass with good fatigue resistance, which helps reduce drivetrain inertia and lets the car react faster. That makes it a solid option for racers wanting sharper turn-in and quicker mid-corner corrections.

Fitment tips and required extras

Replacing a standard gear or steel ball differential joint will require a drive cup protector (B8-500DP?360) to keep the dogbone end of the universal shaft secured. The Yokomo Y2-501MRA kit includes matched left and right joints so you can complete the swap on one axle.
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.

Will aluminium joints handle repeated club racing use?

Yes, when used with correct maintenance and compatible diff grease, aluminium joints are durable enough for regular club racing conditions.

Do I need to change universal shafts when installing these joints?

No shaft change is normally required, but ensure the dogbone ends seat properly and fit the specified drive cup protector B8-500DP?360 for secure retention.

How do these affect diff feel compared to steel joints?

Aluminium joints tend to reduce rotating mass versus steel, producing a slightly crisper diff feel and faster transient response without changing preload settings.
