Description
S&S 585 Cam Kit For Harley Twin Cam
Features:
- Quick installation; reuses many stock components
- Camshafts that exceed the limits of the stock valve springs require the use of special high lift springs. Most S&S cams have higher lift than stock and are designed to take advantage of the extra flow of ported stock heads or S&S Super Stock heads. Due to the high lift of these cams, S&S adjustable pushrods are recommended.
- To get the best performance from a performance cam installation, a high flow intake and exhaust system is also recommended.
- Quick installation and Easy Start Cams allow stock starter to start any engine.
- Kit contains cams, gear cover gasket, cam bearings, and instructions.
- 1999-2004 stock springs will handle camshafts with lift up to 0.510″. If a camshaft with higher lift is installed, high performance valve springs capable of handling a greater lift must be used.
- 2005-up stock valve springs will handle camshafts with lift up to 0.585″. If a camshaft with higher lift is installed, high performance valve springs capable of handling a greater lift must be used. Cams with over 0.585″ of lift will cause interference between the valve spring top collar and the valve seal with stock cylinder heads.
- Installation of S&S chain drive cams requires special tools. Attempting the cam change operation without these tools will be difficult. Damage can result which will not be covered under warranty.
- S&S Cycle chain drive cams are compatible with the stock splined chain sprocket used in 2000-06 Twin Cam 88 engines, but may be used in 1999 engines if the Harley-Davidson 2000-06 splined rear cam sprocket and appropriate 2000-06 sprocket spacer are used.
- For lifts over.510″ S&S strongly recommends that the stock chain drive cam be upgraded to the S&S Cycle gear drive or to the H-D part number 25284-08. This kit upgrades the problematic spring loaded chain tensioners to more reliable hydraulic tensioners, and also upgrades the oil pump
- 585 Camshafts are designed for 88 to 95 CID engines with compression ratios from 9.7:1 to 10.5:1 and 100 to 124 CID engines from 9:1 to 10:1 compression. Provides massive horsepower and torque increases starting at 3000rpm and holds steady all the way to redline. 3500-6000 rpm for 88″ – 103″ engines and 2500-5500 for larger engines
