This bearing will fit will fit all models as front \u0026amp; rear outer cam bearings.   The 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","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":50024032633160,"sku":"503608","price":46.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2711\/4344\/files\/503608.jpg?v=1778632330","url":"https:\/\/holydeath.com\/products\/koyo-camshaft-ball-bearing-outer-front-rear","provider":"Holy Death Motorcycle Co.","version":"1.0","type":"link"}
