The Andrews 21G gear-drive cam turns a heavyweight Twin Cam into a hard-hitting torque machine off the line. Designed to work with stock compression and pistons, it installs as a drop-in setup for immediate, aggressive throttle response and strong pull across the everyday powerband. Twist the grip, leave the line hard and take control of every straightaway.
