Yokomo SD-644CA Center Drive Cups — Resin 2pc Spare for Drift Package  [SD-644CA]

Resin center drive cups for drift drivelines

This resin center drive cup is supplied as part of a drift package and comes as a two-piece RC-scale spare. The part acts as the interface in the center driveline, transferring rotation between shafts in many common drift drivetrain layouts.

Installation is simple: the cups press or slide onto the mating shaft ends inside the center drive assembly and are kept in place by the existing driveline hardware. Inspect the cup faces for cracks or heavy wear before reuse, and replace both pieces together to preserve consistent driveline play.

From a setup and maintenance viewpoint, resin cups offer low mass and predictable wear versus metal options. They are intended as routine replacement items to restore positive driveline engagement and reduce slop that can affect steering and throttle response in drift rigs. This item contains 2 pcs for pair-wise replacement.
