This bearing will fit will fit all models as front \u0026amp; rear outer cam bearings. \r\n\r\nThe MoCo redesigned the Twin Cam rear outer cam bearing from ball (OEM 8990\/A) to a roller bearing style (OEM 8983\/MCS 921138) in 2001. This was done to help prevent failing ball bearings on, specifically, rear (=drive side) cams that are heavier loaded. This 01-up roller style bearing is a 3-piece design that is more heavy duty than a roller bearing. No other parts changed during the bearing changes. The early 99-00 style ball bearings will still fit all 99-06 models front \u0026amp; rear. Using front \u0026amp; rear ball bearings present no issues on cam driven gears.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Ball bearings cam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e HDBB0010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":62971828437322,"sku":"MSH-503608","price":51.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/503608k.jpg?v=1786908579","url":"https:\/\/partsdenmark.com\/es\/products\/sonnax-koyo-camshaft-ball-bearing-outer-front-rear","provider":"Parts Denmark","version":"1.0","type":"link"}
