Screamin’ Eagle Stage upgrades offer complete street compliant performance configurations engineered to generate specific torque and horsepower gains for Sportster®, Twin Cam and Milwaukee-EightTM engine families. Eliminating all the guesswork and trial-and-error testing normally associated with engine modifications. Stage upgrades include everything needed to enhance the bike’s performance.

“ I want simple bolt-on performance upgrades that

enhance the performance, look and sound of my

motorcycle”

SCREAMIN’ EAGLE® STAGE KIT OVERVIEW

TORQUE: “ I want instant passing power at cruising and

highway speeds”

POWER: “ I want to feel the power build and then pull all

the way to the redline”

• Most cost-effective step to improve performance

• The foundation for future performance upgrades

• Match any Screamin’ Eagle high-flow air cleaner and exhaust, along with the proper ECM calibration to increase the air flow into and out of the engine

• Choose a TORQUE CAM or POWER CAM based on riding style

• A performance cam increases both the lift in the valve train (pushing the valve open further) and the duration of the valve opening (how long the valve stays open)

• An increase in engine displacement allows the engine to swallow more air and fuel, a higher compression piston squeezes the air and fuel into a more volatile mixture and when combined, generates more power when ignited

• Displacement increases are accomplished with larger cylinders, matching pistons, and the proper cam upgrade

• Highest level performance upgrade available to provide a maximum increase in displacement, compression and flow

• Higher-flowing CNC ported cylinder heads and larger bore throttle body increase the velocity and feed large volumes of air and fuel into the engine, which maximizes power on a larger displacement engine

“ I want instant power that lasts throughout the entire

RPM Range. Bigger is better.”

“ I ride hard and want the absolute best performance

upgrade available. Try to keep up...I dare you!”
