Go big or go home. This is our demo 2019 Street Glide with the Screamin Eagle 131 kit fitted along with Vance & Hines Raider mufflers and a S/E extreme heavy breather. With the largest displacement of any Harley-Davidson Stage Kit, this 114CI to 131CI Stage IV Kit was designed to deliver maximum horsepower all the way to the redline. Packaged with patent-protected cylinder technology, it allows for the largest bolt-on engine upgrade to any Milwaukee-Eight motor. Features new CNC-ported heads with 1mm bigger valves and fully machined combustion chambers. Coupled with the kit's high-lift SE8-517 cam, high compression pistons and a 64mm throttle body and intake manifold, this combination delivers a thrilling 131 ft-lb of torque and 121 HP rear-wheel output. Its designed to run wide open at high-end RPMs and provide a significant boost of torque from cruising speed. You'll feel the difference as soon as you twist the throttle.
