Designed for the FANTOM EP 4WD, Kyosho EFW004 gold anodised front double bearings provide a direct bearing swap. Exchanging the original 6x15x5mm wheel shaft bearing for two 6x10x3mm bearings lowers vibration and trims friction for cleaner power delivery.
The gold anodised finish resists wear and looks tidy on the hub, while the double-bearing arrangement improves axial stability and drivetrain efficiency. This upgrade is commonly used to reduce mechanical losses and sharpen handling.
Prior to installing the Kyosho EFW004 bearings, clean the wheel shaft and check for burrs. Correct seating and minimal, appropriate lubrication will ensure the best running characteristics.
