CHAIN DRIVE CAM KITS FEATURES AND BENEFITS • Increase performance at an affordable price • Quick installation—reuse many stock components • Easy Start Cams allow stock starter to start any engine KIT CONTENTS • Cams • Installation Kit: gearcover gasket, bearings, retaining ring, o-ring, thread lock • Instructions If OES, 509 or 510C cams are used with the stock chain drive system in Twin Cam 88® engines, it is recommended to use cylinder heads with stock valve springs or performance valve springs with no more than 160 lb. of seat force. For more demanding applications, we recommend the S&S gear drive cams. When using 1999–'06 chain drive cams for lifts over .510", S&S strongly recommends that the stock chain drive be upgraded to the S&S gear drive or to the HD® #25284-08 or #25284-11 hybrid plate. This kit updates the problematic spring loaded chain tensioners to reliable hydraulic tensioners and also upgrades the oil pump. 551 and 583 cams are not recommended with compression ratio of 10:1 or higher. S&S can do a special order cam. Contact your S&S Customer Service Representative for more information. †† This cam kit is not for touring models and does not work with compression over 9.9 to 1.
