This Yokomo Y2-508A kit supplies the small replacement parts used in servicing ball-type differentials for RC models. The bundle contains the T-nut, adjustment screw, coil spring and O-ring intended for routine maintenance or part replacement during rebuilds.
Aimed at preserving adjustment accuracy, the kit is used when dismantling and reassembling a ball differential to recover adjustment range and preload response; renewing springs and O-rings helps maintain smooth operation and grease retention.
Use this kit when rebuilding a ball differential to replace worn adjustment parts and protect adjustment feel; recommended to keep a spare kit if you perform diff rebuilds frequently.
