Center drive shaft for YZ-4S

This is the standard center drive shaft designed for YZ-4S scale RC use, supplied under part number S4-010C71A. It uses a 71mm bone (dogbone) length intended for setups that incorporate a slipper clutch, and serves as the rear center connection in the drive train.

The component is an exact-fit service item for models listed as compatible, intended to replace worn dogbones or to be used when converting or maintaining a slipper clutch arrangement. Fitment focuses on alignment and secure retention of the dogbone at the drive cups and differential outputs.

When installing, verify seating in the drive cups and check for play at both ends; the shaft plays a tuning role by affecting driveline lash and spin-up characteristics in slipper-equipped setups.
