Description

S&S S&S, chain drive MR103 camshaft kit

99-06 Twin Cam (excl. 2006 Dyna) (NU)

Complete kit with two chain driven camshafts with installation kit that includes a gear cover gasket, cam bearings, retaining ring, o-ring and thread locker. Note: Not compatible with S&S 79cc heads. Note: Owners of 1999 Twin Cams must separately purchase the splined 00-06 style driven gear (503575 Andrews). 00-06 models can re-use stock 34 tooth driven gear. Note: When using 99-06 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 convert to the 06-up hydraulic chain tensioners.
