This 93mm dogbone is intended for use on YZ-4S vehicles when a center differential is installed. It forms the driveline connection from the center diff output to the rear assembly, so confirming correct length and fit is essential to avoid drivetrain binding.
Installation notes: verify seating depth and drive angle in the YZ-4S rear assembly, check that the dogbone slides freely in the differential cup and rear axle cups, and ensure no interference with gearbox or suspension travel before use. Test on low power and make adjustments as needed.
Tuning role: using the correct 93mm center spacing preserves the intended geometry and allows accurate tuning of the center differential without introducing length-related anomalies.
