This bearing will fit will fit all models as front \u0026amp; rear outer cam bearings. Note: The MoCo has redesigned the Twin Cam rear outer cam bearing from ball to a roller bearing style in 2001. This was done to help prevent failing ball bearings on; specifically; rear (=driveside) cams that are heavier loaded. This 01-up roller style bearing is a 3-piece design that is more heavy duty than the 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\u003ch2\u003eFitment\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e99-06 Twin Cam (Excl. 2006 Dyna) (NU)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e S\u0026amp;S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e MOTOR PARTS \u0026gt; CAMS BEARINGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e 978145\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePart Numbers\u003c\/h2\u003e\n\u003cp\u003eMCS Part Number: 978145\u003cbr\u003eManufacturer Part Number: 31-4081\u003cbr\u003eOEM Number: 8990\u003c\/p\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44334625784128,"sku":"MCS978145","price":17.79,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/978145k.jpg?v=1776024081","url":"https:\/\/hogparts.co.uk\/products\/mcs978145","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
