The Kingpin Rule combines the Kingpin Ultra Low RG w/DynamiCore and our popular ECA-XR solid reactive coverstock. With this combo the Kingpin Rule is the perfect weapon for heavy oil, producing more hook and backend combined with amazing pin carry. The new Kingpin Rule will have you ruling not only over the pins but your competition as well! Clean your ball with Brunswick’s Big B Bowling Ball Cleaner after every use to reduce oil absorption.
