Since 1915, Hastings Manufacturing Company® in Hastings (Michigan) USA, has been a world power in piston ring engineering and manufacturing. Hastings revolutionised oil control ring design with the invention of the Hastings Flex Vent® oil control ring, and it is now the accepted standard in the industry.

The top compression rings are moly, oil rings are chrome with Flex Vent® technology, a three-piece design allows rails to be manufactured with a small cross sectional area for better conformability to bore.

Hastings only manufacture piston rings, they believe that manufacturing the best product takes a singular and constant focus. This keeps them focused on what they do best with the highest standards to exceed original manufacturers specifications for longevity, smooth operation and maximum performance.
