Andrews Conversion Chain Drive Cam for Harley Twin Cam Models 1999-2006

Upgrade your 99-06 Twin Cam (excluding 06 Dyna Glide) with conversion chain drive cams designed to accept newer roller-style cam chains while replacing spring tension cam chain adjusters with later-style hydraulic adjusters for longer service life. These cam grinds are engineered to work with stock lifters, delivering proven performance characteristics comparable to earlier models running the same grinds.

Installation requires a 07-15 cam plate, oil pump, cam sprockets and chains, and both hydraulic chain adjusters (not included and must be purchased separately). A complete list of required components is supplied with each set of cams. Made in the U.S.A.

GRIND OPTIONS & PERFORMANCE CHARACTER

• Mild upgrade with stock-like manners; typically no retuning of the stock system is necessary.
• Strong low-to-mid rpm torque for heavy bikes, two-up touring, and everyday rideability.
• Broad torque band with smooth idle; runs best with low-restriction exhausts.
• High-rpm focused power for maximum torque and horsepower (compression and clearances must be verified).
• Many options are bolt-in and can be used with stock valve springs and tappets (application-dependent).
• 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. 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.
