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

Rear center dogbone functional summary

This is a 93mm dogbone built to serve as the rear center driveshaft when installing a center differential on YZ-4S projects. It links the differential output to the rear drivetrain, so fit and length are the main factors 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 produce driveline binding and affect handling, so test fit at low throttle and make incremental adjustments.

Tuning role: this dogbone preserves the designed 93mm center spacing and influences how the center differential transfers torque under load. Using the correct length helps you evaluate differential settings without introducing binding from incorrect geometry.
