Steel drive cups for BD5/BD7 gear differentials

This is a replacement steel drive cup designed for BD5/BD7 series gear differential units. The component serves as the interface between the differential output and the drive shaft, and is specified as a direct-fit replacement for the models listed in the compatibility section.

Use this part when inspecting or rebuilding a gear differential to restore a solid fit at the output interface or when worn drive cups are producing slop or uneven engagement. As a steel part, it is chosen for wear resistance compared with softer alloys, and is intended purely for RC-scale gear differentials.

Installation requires removing the differential from the chassis, separating the differential case if fitted, and transferring the drive cup onto the output shaft following the differential manufacturer's service practice. Verify radial runout and fit after installation and reassemble the differential to the chassis before testing under low load to confirm correct engagement.
