Screamin’ Eagle Engine Upgrade

Screamin’ Eagle Milwaukee-Eight Stage III Kit – 107CI to 119CI. Fitted from just £2,600.

This kit was developed for the rider looking for a solid “seat of the pants” increase you can feel – every time you roll on the throttle. The increase in displacement and the bump in compression deliver a significant increase in torque and power over stock while restoring the sensation of riding solo when taking that long trip with a passenger and luggage.

The Stage III 107CI to 119CI upgrade delivers up to 17% more torque and increases power by up to 23% when compared to the Original Equipment 107ci engine configuration. Plus there’s a one-year manufacturer’s warranty and eligibility for coverage under factory vehicle warranty when installed within 60 days of vehicle purchase.

The Screamin’ Eagle Stage III Kit includes: 

  • 4.075″ Bolt-On Cylinders

  • Forged 11:1 High Compression Pistons

  • High performance Piston Rings and Tappets

  • SE8-498 Cam, Performance Valve Springs

  • Multi-layer coated Head Gaskets

  • Cylinder Base & Cam Cover Gaskets

  • High-Capacity Clutch Spring
