Trim rotating mass on your YD-2 with the Yokomo Y2-501MRA

Upgrade to the Yokomo Y2-501MRA Aluminium Ball Differential Joint Set to cut drivetrain weight while retaining robustness. These aluminium joints are matched for the YD-2 family and replace conventional gear diffs to sharpen response and handling balance on technical layouts.

Why aluminium shows on the lap times

Aluminium offers lighter moving parts and solid durability, which helps reduce inertia and improves how quickly the car reacts to driver input. That makes it a practical choice for circuit conditions where rapid changes of direction matter.

Installation and compatibility advice

When fitting the aluminium joints in place of a gear or steel ball differential, remember to fit a drive cup protector (B8-500DP?360) to secure the dogbone end of the universal shaft. The Yokomo Y2-501MRA kit contains both left and right units for a full axle replacement.
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 these diff joints on a converted drift YD-2?

Yes, they can be used on drift-spec YD-2s; the reduced mass helps with throttle response and rotation control during transitions.

Is any special grease required for aluminium joints?

Use standard diff grease compatible with aluminium and steel interfaces. Avoid abrasive compounds and check for recommended viscosity from your diff manufacturer notes.

Will these change drivetrain geometry or toe settings?

No, the joints replace the existing diff output hardware without altering suspension geometry, but always recheck alignment after any drivetrain work.
