Carrillo single connecting rod for the Opel C20XE Pro-SA uses a 3/8" WMC bolt and is offered as an individual replacement component. The Pro-SA geometry and WMC bolt specification make it suitable for precise replacement during engine repair or modification on C20XE engines where only one rod needs service rather than a complete set.
