NOTE: 99-06 Twin Cam motors (except 06 Dyna Glide) cannot use the 07-17 cams, as the bearing journal on the earlier motors is .875” in diameter and the 07-17 cams are 1.000” in diameter. The “N” series of cams feature the .875” bearing journal, yet still accept the new-style cam support plate. NOTE: 99-01 model motors must use the Andrews rear cam sprocket Drag PART #0925-0147. 2002-2006 models must use the stock rear cam sprocket, OEM #25728-06. NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. FOR 99-06 TWIN CAM (EXCEPT 06 DYNA GLIDE) “26N” GRIND CAMS • Bolt-in cams for low rpm torque and two-up touring • Add more torque and horsepower at low and middle rpm range (1800-5200 rpm) • Can be used with stock valve springs and tappets “37N” GRIND CAMS • Bolt-in cams for 88” or 95” motors • Smooth idle, broad torque band • Run best with low-restriction exhausts (2200-5800 rpm) • Can be used with stock valve springs and tappets
