Tight and consistent wall tolerances are maintained throughout the manufacturing process.\n\nThe PR7940 set is designated as 'Size 1,' representing a nominal standard size suitable for most applications, offering standard oil clearance compared to factory specifications. For reference, Size 0 bearings provide 0.001\" less oil clearance, while Size 2 bearings offer an additional 0.001\" more oil clearance than factory specifications.","brand":"Cosworth","offers":[{"title":"Default Title","offer_id":52687473312056,"sku":"PR7940","price":99.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661670397.jpg?v=1784884563","url":"https:\/\/store.motormia.co\/products\/main-bearing-set-1341","provider":"MOTORMIA","version":"1.0","type":"link"}
