This Yokomo Y2-508A kit provides the small service parts required when rebuilding ball-type differentials on scale RC models. The pack includes the T-nut, adjustment screw, coil spring and O-ring needed for routine servicing or part replacement during differential work.
A workshop-focused kit, it is intended to restore adjustment travel and preload control while disassembling and reassembling a ball differential; useful for replacing fatigued springs or renewing sealing O-rings to hold grease.
Fit these parts during a ball-differential rebuild to renew adjustment components and preserve tuning feel; good practice to keep spares if you perform frequent diff servicing.
