Yokomo SD-644CA 2pc Resin Centre Drive Cups for Drift Package  [SD-644CA]

Centre drive cup replacement for drifting

This item is a resin centre drive cup included with a drift package, provided as an RC-scale two-piece spare. The component links the central driveline shafts, transferring torque between mating shaft ends in many standard drift setups.

Fitting is straightforward: cups either press-fit or slide onto the shaft ends inside the centre drive assembly and are retained by the existing hardware. Always examine the cup faces for hairline cracks or excess wear before reinstalling, and swap both cups together to maintain even driveline clearance.

For tuning and maintenance the resin option keeps weight down and delivers predictable wear compared to metal cups. Use these as scheduled replacement parts to recover accurate driveline engagement and reduce play that can dull steering feel. Supplied as a pair (2 pcs).
