{"product_id":"s-s-m8-chain-driven-540c-camshaft-kit","title":"S\u0026S, M8 chain driven 540C camshaft kit","description":"Torque cam designed to offer generous pulling power up that hill; or quickly passing a big rig in traffic for big bore motors. Real life touring power below 6000RPM but still good for respectable HP numbers. Kit includes cam; all required bearings; o-rings and hardware. Gear drive cams provide improved valve timing accuracy but more mechanical sound; when compared to chain driven cams. The additional mechanical sound is the reason why OEM runs chain driven cams.   Note: This is a small base circle cam. Requires adjustable pushrods and heavy duty valve springs. S\u0026amp;S Recommends 558660 Quickee pushrod \u0026amp; cover kit and 565784 S\u0026amp;S .605\" heavy duty valve Spring kit.  Note: For best performance it is; like with all performance cams; recommended to use a free breathing air cleaner and exhaust system.  Note: With each cam change S\u0026amp;S recommends their 583903 Precision tappet assembly set. Note: See paper or online Motorcycle Storehouse catalog for the S\u0026amp;S camshaft specification chart.\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 18-26 Softail; 17-26 FLT\/Touring (excl. 23-26 VVT); 17-26 Trikes\u003c\/p\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":54307808051527,"sku":"597883","price":358.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/7812\/0519\/files\/597883k.jpg?v=1784479974","url":"https:\/\/www.chopperessentials.com\/products\/s-s-m8-chain-driven-540c-camshaft-kit","provider":"Chopper Essentials Co.","version":"1.0","type":"link"}
