Allow you to upgrade your 99-06 Twin Cam (except 06 Dyna Glide) to the newer roller-style cam chains and replaces the spring tension cam chain adjusters with the later-style hydraulic adjusters for longer life
Cam grinds listed are designed to be used with stock lifters; they require the installation of a 07-15 cam plate, oil pump, cam sprockets and chains, and both hydraulic chain adjusters (these parts are not included and must be purchased separately)
A list of required components is supplied with each set of cams
Performance should be similar to earlier bikes with the same cam grinds
Made in the U.S.A.

"37N" GRIND CAMS

• Run best with low-restriction exhausts (2200-5800 rpm)
• Can be used with stock valve springs and tappets
• Bolt-in cams for 88" or 95" motors
• Smooth idle, broad torque band
• Fits: Harley Twin Cam 1999-2006 (Excluding 2006 Dyna)

NOTE: 99-06 Twin Cam motors (except 06 Dyna Glide) cannot use the 07-15 cams, as the bearing journal on the earlier motors is .875" in diameter and the 07-15 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  $69.95. 2002-2006 models must use the stock Rear cam sprocket, OEM #25728-06.
