Yokomo S4-010B93A Center Diff 93mm Dogbone for YZ-4S Rear Center  [S4-010B93A]

Center diff rear dogbone overview

This is a 93mm dogbone intended for RC-scale use as the rear center bone when installing a center differential on YZ-4S projects. It serves as the driveline link between the center differential output and the rear drivetrain, so fit and length are the primary concerns when replacing or upgrading parts.

Installation notes: verify the seating depth and drive angle in the YZ-4S rear assembly, confirm the dogbone slides freely in the differential cup and rear axle cups, and check clearances with the gearbox and suspension travel before running. Small alignment errors can affect driveline binding and handling, so test fit at low throttle and make incremental adjustments.

Tuning role: this dogbone maintains the designed 93mm center spacing and affects how the center differential transfers power under load. When swapping to a center diff setup, use this part to retain intended geometry and to evaluate differential settings without introducing length-related binding.
