This is Xray’s new precision moulded 84-tooth spur gear for the XB4 made from their exclusive secret blend of composite material, allowing the gear to run yet be robust enough to handle high performance brushless motors. The spur gear is designed to have the lowest possible weight whilst remaining strong and light. Each gear is stamped with the tooth number for easy identification.
