Bezerk RC YZ-4 SF slipper eliminator
Coming from Bezerk RC and made for the Yokomo YZ-4 SF is a slipper eliminator. The set includes parts to do away with the slipper clutch in favour of a fixed, simpler driveline which makes for a lighter drivetrain for stock racing classes. The design allows to use standard “on-road” 48 pitch or 64 pitch spur gears and included in the set are the parts marked in red, a spur gear plate, a small spacer, a stepped spacer to fit just inside the bearing and a spacer to replace the spring.
