The XRAY 364172 Narrow Slipper Clutch Outdrive Adapter provides a robust replacement part for racers and weekend tuners alike. Built for the XB4 2020 Specs, the adapter is manufactured from Hudy Spring Steel and undergoes a hardening step to boost lifespan and maintain consistent performance in regular use.
Made from Hudy Spring Steel, this outdrive adapter balances strength and low weight to resist wear while keeping rotating mass down. The black surface finish gives a neat appearance and adds extra protection against corrosion and track grime.
Designed to slide into XB4 slipper systems with minimal fuss, the narrow profile helps reduce rotational inertia and can sharpen throttle response. It is a practical upgrade for anyone maintaining competitive lap times or refreshing an aging drivetrain.
