Stage Kit Upgrades

Benefits
Ideal for riders that want to enhance the performance, look and sound of their motorcycle

Basics
Most cost-effective step to improve performance and the foundation for future performance upgrades.

Match any Screamin'Eagle high-flow air cleaner and exhaust with the proper ECM calibration to increase the air flow into and out of the engine.

Performance
The rider will feel up to a 10% increase in performance when compared to stock bikes throughout the entire RPM range

Benefits
TORQUE KIT- Ideal for riders looking for instant passing power at cruising speeds

POWER KIT- Ideal for riders who want to feel the power build and pull all the way to the redline

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

A performance cam increase 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)  

Performance
TORQUE KIT- The rider will feel up to a 15%* increase in performance when compared to stock bikes in the low-to mid-RPM range

Experience crisp throttle response and acceleration that can be felt at slower speeds, perfect for passing slow moving vehicles without downshifting

POWER KIT- The rider will feel up to a 25%* increase in performance when compared to stock bikes in the mid-RPM to upper RPM range

Experience an adrenaline-pumping burst of speed while heading toward the redline  


Benefits
Ideal for riders who want the largest engine displacement and increased power throughout the entire RPM range

Basics
AN increase in engine displacement allows the engine to swallow more air and fuel, while a higher compression piston squeezes the air and fuel into a more volatile mixture, generating more power when ignited.

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

Performance
Riders will experience a performance increase throughout the entire RPM range, with up to a 35%* increase when compared to stock bikes in the mid-to upper-RPM range 

Produces instant passing power without downshifting

Delivers excellent stoplight to freeway speed and on-ramp acceleration

Benefits
Ideal for riders who want the absolute best Harley-Davidson performance upgrade available

Basics
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

Combines ported cylinder heads and larger throttle body in combination with cylinders, matching pistons and proper cam upgrade

Performance
The rider will feel exceptional acceleration, delivering significant gains and up to a 40%* increase when compared to stock bikes in the upper-RPM range
