Yokomo SD-644CA Center Drive Cups — Resin center drive cups, 2pcs spare for drift package  [SD-644CA]

Center drive cups for drift setups

This is a resin center drive cup supplied as part of a drift package, supplied as an RC-scale spare in a two-piece set. The component functions as the interface in the center driveline, transferring rotation between shafts in many standard drift drivetrains.

Installation and fit are straightforward: the cups press or slide onto the mating shaft ends within the center drive assembly and are retained by the existing driveline hardware. Check the cup faces for signs of cracking or excessive wear before reuse, and replace both pieces as a matched pair to keep driveline play consistent.

From a tuning and maintenance perspective, resin cups offer light weight and predictable wear characteristics compared with metal alternatives. They are intended as routine replacement parts to restore driveline engagement and reduce slop that can affect steering response and throttle feel in drift setups. This item contains 2 pcs for pair-wise replacement.
