Screamin' Eagle Twin Cam Stage III 103CI to 110CI Kit

The Harley-Davidson Screamin' Eagle Twin Cam Stage III Kit is engineered to build a powerful 110 cubic inch Twin Cam hauler without removing the motor from the chassis. This Stage III Street Performance Kit combines system-matched Screamin' Eagle components, including 4" bolt-on big bore cylinders, high compression pistons, and performance cams with original equipment cylinder heads for an enhanced boost in torque and performance. The kit includes 4" flat top pistons, SE-585 high-lift cams, perfect fit pushrods, SE high capacity roller tappets, high performance valve springs, a heavy-duty clutch spring, and a top-end gasket kit. This kit is designed for model year 2016-2017 Softail and 2014-2016 Touring models. It does not fit Trike models, FLSS, FLSTFBS, CVO™ 110 models, or models with engine cases that have been machined for large-bore cylinders. Additionally, separate purchase of the Cam Drive Retention Kit P/N 25566-06 and a Cam Spacer Kit P/N 25928-06 is recommended. Twin-Cooled models require model-specific head gaskets. All EFI-equipped models require a dealer-installed ECM calibration download or the use of the Screamin' Eagle Street Tuner Kit (sold separately). Recalibration is required for proper installation, and labor costs are not included. If installed by an authorized Harley-Davidson Dealer within 60 days of vehicle purchase, compliant kits do not impact the vehicle's limited warranty.
