Looking for an upgrade to take your Harley-Davidson motorcycle to the next level? Look no further than Sy'S H-D® and our Screamin' Eagle Performance Upgrades.
Choose from a Stage II upgrade to give your H-D a lift, a Stage III upgrade to pump up the volume, or a Stage IV upgrade to top it off. These upgrades are designed to give your Harley-Davidson the power and performance you've been looking for. With Stage II, you'll get a significant increase in torque (Torque Cam) or horsepower (Power Cam). This kit is perfect for those looking to upgrade their ride for improved passing power at cruising speeds or who want to feel the power build and pull all the way to the redline.
For those looking for even more power, Stage III is the way to go. A Stage III includes everything in a Stage II PLUS big bore cyinders and matching pistons and the proper cam upgrade. This is ideal for riders who want the largest engine displacement and increased power throughout the entire RPM range.
Finally, for the ultimate upgrade, choose the Stage IV upgrade. With everything included in the Stage III PLUS higher-flowing CNC ported cylinder heads and a larger bore throttle body, this increases the velocity and feeds large volumes of air and fuel into the engine, which maximizes power on a larger displacement engine. Your Harley will truly become a force to be reckoned with. This kit is perfect for riders wanting the absolute best Harley-Davidson performance upgrade available.
No matter which stage you choose, the Screamin Eagle Performance Upgrade kits are backed by Harley-Davidson's legendary quality and craftsmanship. So why wait? Upgrade your Harley-Davidson today and experience the power and performance you've been looking for.

STAGE II - GIVE IT A LIFT
STAGE II BENEFITS
Customers have a choice of a TORQUE CAM or POWER CAM based on their riding style.
A TORQUE KIT is ideal for riders looking for instant passing power at cruising speeds.
A POWER KIT is ideal for riders who want to feel the power build and pull all the way to the redline.
A performance cam increases both the lift in the valve train (pushing the valve open farther) and the duration of the valve opening (how long the valve stays open).
STAGE II 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 to upper RPM range. Experience an adrenaline-pumping burst of speed while heading toward the redline
STAGE III - PUMP UP THE VOLUME
STAGE III BENEFITS
Ideal for riders who want the largest engine displacement and increased power throughout the entire RPM range. 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.
STAGE III 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. The Stage III upgrade produces instant passing power without downshifting and delivers excellent stoplight to freeway speed and on-ramp acceleration.
STAGE IV - TOP IT OFF
STAGE IV BENEFITS
Ideal for riders who want the absolute best Harley-Davidson® performance upgrade available. The Stage IV upgrade provides the 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.
STAGE IV 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.
* Stage II, Stage III or Stage IV upgrades require the motorcycle to already have a Stage I upgrade. For specific performance results refer to the Screamin’ Eagle® Parts & Accessories Catalogue. Declared performance values represent SAE J-1349 transient peak power output. Dynamometer settings, motorcycle condition, variation, climate and other factors can affect performance output and can vary from the performance values declared by Harley-Davidson®.
