Pimp your engine!

The biggest machine with Harley-Davidson Stage Kits: 131 cui

GO BIG or go home!

 

This Screamin’ Eagle Stage IV kit is designed for maximum power! It enables the biggest bolt-on upgrade for a Milwaukee Eight engine to 131 cui, at 183 Nm and 124 horsepower at the rear wheel – and this, without removing the engine from the frame!

The kits contain everything you need to pimp your engine (varies by kit and model):

CNC machined cylinder heads with CNC machined chambers and larger valves (high performance injectors), forged high compression pistons, high lift camshaft, high performance cam bearings and high performance tappets, steel sleeve cylinders, 64mm throttle bodies with cast iron manifolds, Stage IV timer covers, and many others. Depending on the model, EPA compliant according to 49 US Environmental Protection Agency, without certificate (for racing & show purposes).

Different versions available for Harley-Davidson Touring models and Softails.

Other kits, also for the 107 Milwaukee-Eight engine, are also available. You can find more information in our online shop and from our consultants.
