KYOSHO FW05-R/FW05RR Light Weight Clutch Hub by 3Racing FW05-RR008  [FW05-RR008]

Lightweight clutch hub for FW05-R/FW05RR

This clutch hub is an RC-scale replacement part designed for Kyosho FW05-R and FW05RR on-road models, supplied by 3Racing as part number FW05-RR008. Its purpose is to reduce rotating mass at the clutch interface, helping the clutch engage and disengage with crisper response during throttle transitions.

Fitment is focused: the hub matches the FW05-R/FW05RR clutch assembly dimensions and mounting points. When preparing for installation, confirm spline alignment and clutch shoe clearance before final tightening. Use threadlocker only where the manufacturer of your clutch assembly recommends it.

In tuning work, a lighter clutch hub shifts the balance between slip and grab, making it easier to dial in launch behavior and mid-corner throttle reapplication. Test changes with measured runs rather than large step adjustments, and note effects together with clutch spring and shoe compound changes.
