Andrews 21H Cams for 2007-2017 Harley Twin Cam

Product Description

Andrews 21H Chain Drive Cam Set for Harley Twin Cam

Improve low-end and midrange torque on your Harley-Davidson Twin Cam with the Andrews 21H Chain Drive Cam Set. Designed as a bolt-in street cam for heavier motorcycles, stock compression ratios and stock pistons, the 21H delivers strong, usable power where most street-ridden Harley-Davidson motorcycles spend their time.

With a power range of approximately 1,700-4,800 rpm, the Andrews 21H is an excellent choice for riders looking for increased torque and responsive everyday performance without sacrificing street manners. The cam set is designed for the factory roller-chain cam drive used on 2006 Dyna and 2007-2017 Twin Cam engines and works with stock Harley-Davidson hydraulic lifters and valve springs.
