Andrews TW50 Cams for 1999-2006 Harley Twin Cam

Product Description

Andrews TW50 Chain Drive Cam Set for Harley Twin Cam

Build stronger midrange and upper-rpm power into your early Harley-Davidson Twin Cam with the Andrews TW50 Chain Drive Cam Set. Designed for performance-oriented 95ci engines, the TW50 is an excellent choice for riders looking for increased horsepower without moving to a high-lift cam that requires upgraded valve springs.

The TW50 is designed to work especially well in 95ci engines with stock cylinder heads and approximately 9.5:1 to 9.8:1 compression. With .510" intake and exhaust lift and an operating range of approximately 2,400-6,000 rpm, this cam set delivers its strongest performance through the mid and upper rpm range while remaining compatible with stock valve springs and hydraulic lifters.
