They come with plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. To top it off, King XP rod and main bearings are included, known for their robust construction and ability to handle high loads.
This assembly is set up with a 24-tooth reluctor wheel, which is standard for many LS1 applications.
