{"product_id":"performance-rod-bearings-for-mazda-l3-vdt-engines","title":"Performance Rod Bearings for Mazda L3-VDT Engines","description":"The ACL 4B8172H is a set of high-performance rod bearings engineered for motorsport applications, recognized as a premier component in championship-winning race engines. These bearings are manufactured to exacting tolerances, ensuring consistent accuracy in wall thickness and crush for reliable fit and maintained clearances.\n\nFeaturing a multiple-layer construction, these bearings provide a blend of characteristics that offer high strength and excellent seizure resistance. Unlike some bearings, no flash plating is applied, which further improves bearing retention and maximizes heat transfer. Improved retention is also achieved through higher radial contact pressure, which effectively locks the bearing into the housing.\n\nThe design incorporates increased eccentricity to enhance shape adaptation and compensate for bore distortion that can occur during high-speed operation. The upper bearings feature a full 180° groove, complemented by a partial groove in the lower bearings. Additionally, the tapered groove run-out smooths the big-end supply cut-off, helping to avoid pressure pulsing and cavitation.\n\nThese rod bearings are specifically designed for Mazda L3-VDT engines, fitting the 2007-2012 Mazda Mazdaspeed3, 2006-2007 Mazda Mazdaspeed6, and 2006-2012 Mazda CX-7. The package includes one full set of rod bearings.","brand":"ACL","offers":[{"title":"Default Title","offer_id":52686753988920,"sku":"4B8172H","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660671298.jpg?v=1784876339","url":"https:\/\/store.motormia.co\/products\/performance-rod-bearings-for-mazda-l3-vdt-engines","provider":"MOTORMIA","version":"1.0","type":"link"}
