Steel drive cup replacement for BD5/BD7 differentials

This replacement steel drive cup is made for use with BD5/BD7 series gear differential assemblies. It links the differential output to the drive shaft and is offered as a direct-fit spare for the compatible models listed below.

Fit this component when worn drive cups cause play or inconsistent engagement, or during a full differential rebuild. The steel construction favours long-term wear resistance compared to softer materials, and it is intended for RC gear differentials only.

Fitting the cup involves removing the differential from the chassis, splitting the differential case if necessary, and sliding the drive cup onto the output shaft in accordance with the differential maker's service guidance. Check runout and fit, then complete reassembly and perform a low-load trial run.

How do I confirm this part fits my chassis?

Check the compatibility listing included above; those MRTC-BD7 and MRTC-BD8 model codes indicate the supported chassis where this drive cup will fit.

Is steel the only material option for this part?

This specific item, BD-501GS, is supplied in steel to prioritise wear resistance. Other manufacturers may offer different materials, but this listing describes the steel variant.

What service steps are recommended after replacement?

After installing the drive cup, inspect axial and radial alignment, ensure proper seating on the shaft, then assemble and run the differential slowly to confirm smooth engagement.
