Andrews TW60 Cams for 1999-2006 Harley Twin Cam

Product Description

Andrews TW60A Chain Drive Cam Set for Harley Twin Cam

Build serious midrange and upper-rpm power into your early Harley-Davidson Twin Cam with the Andrews TW60A Chain Drive Cam Set. Designed for 95ci and larger performance engines with extensive cylinder head work, the TW60A is intended for riders looking for maximum torque and horsepower well beyond the range of a mild street cam.

With .560" intake and exhaust lift, 260° duration and an operating range extending to approximately 6,500+ rpm, the TW60A is best suited for properly prepared high-performance Twin Cam builds. High-lift valve springs are required, and Andrews specifies that valve spring coil bind, valve-to-valve clearance and valve-to-piston clearance must all be checked during installation.
