Ring Pull

Huttner Enterprises' patent-pending Ring Pull incorporates a digital load cell attached to an adjustable fixture designed to isolate and pull the ring through the cylinder prior to the piston-ring assembly, allowing a precise measurement of ring drag against the machined cylinder surface. The Ring Pull provides the accurate ring friction data serious engine builders need to determine proper cylinder ring selection and optimize engine performance. It helps facilitate engine cylinder ring preparation prior to assembly, which aids in evaluating cylinder bore surface finishes, measure the consistency of cylinder ring manufacturing and balance ring drag from cylinder to cylinder.
