Kyosho Ball Differential Set II

This Kyosho ball differential set is built for MR03, MM, MM II, RM, and HM drivetrain layouts. It replaces the differential assembly and uses a lightened spur gear holder to trim weight where it matters in the drivetrain.

Key details:

• Ball differential set for MR03, MM, MM II, RM, and HM layouts
• Lightened spur gear holder for reduced drivetrain weight
• Threaded hole on the left wheel hub for adding a set screw
• Improved left-right weight distribution

The added threaded hole gives you a place to install a set screw on the left wheel hub. That makes this assembly a practical replacement when you need to service or rebuild the differential section.
