{"product_id":"main-bearing-set-1337","title":"Main Bearing Set","description":"The King Bearings MB556SI is a set of five direct replacement main bearings, designed for OE applications and suitable for aftermarket gasoline or diesel engine rebuilding, as well as performance engines with factory crankshafts.\n\nConstructed from a bi-metal silicon aluminum material, these bearings feature a 1\/2 groove style with the groove positioned at the upper half of the bearing. This reduction in wear also contributes to lower operating noise, vibration, and prevents excess oil flow.\n\nThese SI-Series main bearings are recommended for applications where improved crankshaft finish is beneficial, particularly on nodular cast iron crankshafts that may have microscopic ferrite peaks due to improper grinding or polishing. The design aims to enhance the lifespan and performance of the engine components.","brand":"King Bearings","offers":[{"title":"Default Title","offer_id":52686469824824,"sku":"MB556SI","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658279527.webp?v=1784874161","url":"https:\/\/store.motormia.co\/products\/main-bearing-set-1337","provider":"MOTORMIA","version":"1.0","type":"link"}
