The Kyosho B0132-20 4mm Bush Set is a handy spare for owners of the EP Jet Stream 600, made to limit friction and slow component wear. These small parts play a big role in preserving smooth shaft rotation and prolonging service intervals on your RC boat.
Fitting fresh 4mm bushings helps reduce play and uneven wear on rotating pieces, which in turn keeps running smoother and more consistent. Regular checks of these bush points will prevent early damage and maintain predictable handling on the water.
Replace the bushings with clean parts and surfaces to avoid trapping grit. Take care to align shafts correctly during installation so the bushing sits square and delivers even support under load.
