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

Overview of the rear center dogbone

This 93mm dogbone is intended for RC-scale YZ-4S builds where a center differential is fitted. It acts as the connection from the center diff output to the rear driveline, so accurate length and clean fit are essential when replacing or upgrading components.

Installation notes: measure seating depth and verify drive angles in the YZ-4S rear section, confirm free movement in the differential cup and axle cups, and check clearances with the gearbox and suspension travel before running. Fit the part and inspect at low throttle to ensure nothing binds.

Tuning role: retaining the specified 93mm spacing lets you assess differential settings without introducing geometry errors, preserving the intended power transfer under load.
