Installation guide: drive cup for BD5 gear diff

This Yokomo BD-501GC aluminum drive cup is supplied as an aftermarket replacement for the BD5 series gear differential and is intended for scale RC applications. It installs as a direct swap where the original drive cup is removed, restoring the drive link between the differential outdrive and the half shafts.

The part is made from aluminum to provide a harder contact area for the drivetrain while preserving the internal geometry of the diff. Fit this component when the existing drive cup shows wear or damage, or when preparing the car for track service and inspection.

The list below shows the chassis model codes that this item supports; always verify fitment with your vehicle service manual before you proceed with installation.

How do I confirm this will fit my chassis?

Compare your car's exact model code with the Compatible Models list above and check the service manual for the BD5 series drive cup dimensions before ordering.

What basic steps are involved in replacing the cup?

Remove the diff assembly, extract the original drive cup from the outdrive, then fit the Yokomo BD-501GC unit ensuring correct alignment and secure fastenings per your diff rebuild procedure.

Should I change other parts when fitting this cup?

Inspect half shafts, outdrives, and surrounding bearings; replace worn elements during the same service to maintain reliable drivetrain engagement after installing the new drive cup.
