Harley-Davidson Screamin' Eagle Stage III Kit

Harley's new Screamin’ Eagle Stage III 103 Performance Upgrade Kit (P/N 92500028, $969.95) may give your bagger that extra grunt for smoother running uphill. This street-legal, Stage III kit gives 2014-later Harley-Davidson Touring models with an Original Equipment Twin Cam 103 engine a boost in everyday performance while maintaining the factory warranty. Designed for use with stock cylinder heads, this street-performance kit produces big torque gains at lower RPM, with the potential to produce 88 horsepower and 100 lb-ft of torque.

The Stage III kit includes high-compression 10.5:1 pistons, big torque SE-585 cams, Perfect Fit pushrods, a high-performance diaphragm clutch spring, high-lift valve springs and gaskets. It does not fit Trike or Twin-Cooled models, and installation requires the separate purchase of primary cover gasket. All EFI-equipped models require ECM calibration (priced separately). See an authorized Harley-Davidson dealer for details. Labor cost not included.
