Designed specifically for Twin Cam engines from 1999 to 2006, excluding the '06 Dyna models, this kit features bolt-in cams that reduce initial crank compression, facilitating easier starts. Once the engine reaches higher RPMs, the centrifugal retraction of the compression release lobe allows the engine to operate with full compression, ensuring no loss of power or performance. Made in the USA, these camshafts include all necessary hardware such as gear cover gasket, bearings, retaining ring, O-ring, threat lock, and instructions for straightforward installation. The kit is optimized for engines with stock 9.7:1 compression ratios up to 10.5:1, delivering increased power in the high RPM range of 3000 to 6000 RPM. It performs well with stock, unported heads but is also highly compatible with S\u0026amp;S CNC ported heads for those seeking further performance gains. Prior to installation, the installer must verify key clearances, including coil bind, valve-to-valve, and valve-to-piston, to ensure optimal operation and longevity. This camshaft kit is an excellent choice for riders aiming to improve startup ease and high RPM power without sacrificing engine reliability or requiring extensive modifications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eEngine start assistance by reducing initial crank compression for easier startup.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAllows normal engine operation with full compression once engine RPM increases.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned as bolt-in replacement for Twin Cam engines from 1999 to 2006 (excluding '06 Dyna).\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptimized for engines with stock 9.7:1 to 10.5:1 compression ratios.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProvides increased power output in the high RPM range of 3000 to 6000 RPM.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes camshafts, gear cover gasket, bearings, retaining ring, O-ring, threat lock, and installation instructions.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with high-quality materials and precision manufacturing.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with stock or CNC ported heads for customizable performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRequires checking coil bind, valve-to-valve, and valve-to-piston clearances prior to installation.\u003c\/li\u003e\u003c\/ul\u003e","brand":"S\u0026S CYCLE","offers":[{"title":"Default Title","offer_id":43031949279326,"sku":"09251041","price":492.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/12780.png?v=1784497242","url":"https:\/\/vtwinvisionary.com\/products\/s-s-cycle-easy-start-camshaft-kit-hp103-chain-drive-for-twin-cam-99-06-excluding-06-dyna-part-number-330-0445","provider":"V-TwinVisionary","version":"1.0","type":"link"}
