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\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctr\u003e\n\u003cth\u003eUnit\u003c\/th\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/table\u003e\u003ch2\u003eFitment\u003c\/h2\u003e\u003cp\u003e99-06 Twin Cam (Excl. 2006 Dyna) (NU)\u003c\/p\u003e\u003ch2\u003ePart numbers\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplier SKU\u003c\/th\u003e\n\u003ctd\u003e921138\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer part\u003c\/th\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"MCS","offers":[{"title":"Default Title","offer_id":58635657773400,"sku":"921138","price":39.86,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/8235\/0680\/files\/921138k.jpg?v=1791035853","url":"https:\/\/deathproofcycles.com\/products\/camshaft-roller-bearing-outer-rear","provider":"Deathproof Cycles","version":"1.0","type":"link"}
