• Allows 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 2007 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
• For 99-06 Twin Cam (except 06 Dyna glide)

• Bolt-in cams with the same output as the stock cams
• Slight power increase when compared to stock
• No retuning of the stock system is necessary
• Can be used with stock valve springs and tappets

• Bolt-in cams with more torque at low and middle rpm range (1,700-4,800 rpm)
• Similar to EV23 for heavy bikes
• Ideal for heavy bikes with stock compression ratios and stock pistons
• Can be used with stock valve springs and tappets

• Bolt-in cams for low rpm torque and two-up touring
• Add more torque and horsepower at low and middle rpm range (1,800-5,200 rpm)
• Can be used with stock valve springs and tappets

• Great cams for motors with 95 inches and 9.8 to 10.2 compression ratio
• Lower TDC lift for easy installation
• Similar to TW37 with different timing (2,000-5,600 rpm power range)
• Can be used with stock springs and tappets

• Bolt-in cams for 88” or 95” motors
• Smooth idle, broad torque band
• Run best with low-restriction exhausts (2,200-5,800 rpm)
• Can be used with stock valve springs and tappets

• Bolt-in cams for 88+” and 9.5:1 to 10.2:1 compression ratio
• Maximum torque and horsepower at middle and upper rpm range (2,300-5,800+ rpm)
• Can be used with stock valve springs and tappets

• Designed for easy installation in 95 inch motors with stock heads
• For lighter bikes with 9.5 to 9.8 compression ratio (2,400-6,000+ rpm)
• Can be used with stock valve springs and tappets, but valve travel must be checked (minimum .620”)
• Piston-to-valve and valve-to-valve clearance must be checked

• Maximum torque and horsepower at higher rpm ranges (2,600-6,200+ rpm)
• Designed for engines with 9.8:1 to 10.2:1 compression ratio
• Coil bind should be checked; can be used with stock tappets (minimum valve travel of .620”)
• Piston-to-valve and valve-to-valve clearance must be checked

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.
