Harley-Davidson 25638-07 Screamin' Eagle Twin Cam Performance Cams- SE-255 Screaming Eagle

Camshafts are a fundamental ingredient in the performance recipe, because they control the timing and duration of all major engine events. They are the primary means by which you can tune your engine's horsepower and torque output. Every cam has unique lift and overlap performance characteristics, which means you need to select cams based on exactly the kind of power you're looking for.

- The ultimate in torque cams, this cam offers substantial increase in low-end torque for engines up to 110 cubic inches with compression ratios up to 10 to 1

- Low-end torque increases are great for heavy bikes or for the person who routinely shifts below 4500 rpm and wants the power available to pass without downshifting

- Cam still makes peak power above 5000 rpm so people with lighter bikes will enjoy the torque increases without feeling like the bike runs out of air at higher engine speeds

- Kit includes front and rear cams

- Splined rear cam is included for exceptional load handling capability

- Gaskets and bearings not included

- Dealer installation is recommended and special tools are required for proper installation
