Screamin’ Eagle Milwaukee-Eight Engine Stage III Kit - 107 to 114CI

    Stage III
Screamin Eagle Milwaukee-Eight Engine Stage III Kit is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Stage III-Great Performance Choice I just purchased a 2018 FLHTKE Ultra Limited and had this Screamin Eagle upgrade installed on it at purchase, as well as the full Sreamin Eagle exhaust system with Street Canon slip ons and the Screamin Eagle air cleaner. Originally, I had chosen the Stage IV upgrade. Long conversation with my dealers P&A Consultant and the Technician who did the work ensued, as did an in-depth review of the dyno charts. Based on the conversations and recommendations, I'm extremely pleased with the way everything works together in this Stage III upgrade. The seat of the pants dyno as well as a real dyno pull supports the numbers advertised. The difference is most apparent when jumping on the freeway, passing others or just going stop light to stop light. I'm EXTREMELY pleased that I went with this on my Ultra Limited!

What is this difference between this kit and the other stage 3 kit

Asked by: Brock93
One of the kits has black cylinders with silver highlights, the other is black only. Otherwise they have all the same parts. Great choice for real world riding.
