{"product_id":"piston-ring-set-94","title":"Piston Ring Set","description":"The Speed Pro R9771-45 Plasma Moly Racing Rings are engineered to deliver increased horsepower and longevity. The top rings are constructed from high-strength ductile iron with a plasma moly facing, ensuring instant seating and extended wear life. Second rings are made from cylinder-friendly cast iron, featuring an oil-controlling taper face profile and an open gap design to minimize inter-ring pressure buildup. Exclusive electro-polished stainless steel SS50 oil rings prevent high RPM deflection, providing excellent oil control even at the highest engine speeds.\n\nThese piston rings are designed for a universal 8-cylinder application with a bore size of 4.040” + .005” (4.045”). The top and second rings have a thickness of 1\/16”, while the oil ring measures 3\/16” with standard tension. They are file-fit, meaning they require gapping by the installer, and are sold as a set. The manufacturer is Federal Mogul, and the warranty is explicitly stated as \"Race Application, No warranty expressed or implied.\"","brand":"Speed Pro","offers":[{"title":"Default Title","offer_id":52663777558840,"sku":"R9771-45","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687712975.jpg?v=1784329524","url":"https:\/\/store.motormia.co\/products\/piston-ring-set-94","provider":"MOTORMIA","version":"1.0","type":"link"}
