Description
Ring wear is one of the fastest ways to lose compression and power in a high-performance engine. The RP3937VMF delivers gas nitride coating that handles extreme combustion pressures while sealing against nickel-silicon-carbide-plated bores with precision fit. If you’re rebuilding a forced-induction or naturally aspirated engine that demands reliability, these rings are engineered to maintain ring-to-bore contact under the harshest conditions.
