S&S Cycle T111 Long-Block Engine Fits Harley-Davidson Twin Cam Dyna and Touring 1999-2017
Take a Twin Cam Dyna or Touring up to 111 cubic inches with a complete bolt-in S&S long-block. The T111 is a top-end and cam-chest assembly that drops onto an existing Twin Cam chassis crankcase, delivering the displacement, cam profile, and S&S valve-train spec that turn a stock 88, 96, or 103 into a real performer.

Fitment Notes
- Compatible with select 1999-2017 Harley-Davidson Twin Cam Dyna and Touring chassis only.
- 1999-2006 585 Cam variations fit 1999-2005 Dyna and 1999-2006 Touring with the Twin Cam 88 engine; the 2006 Dyna is excluded because it used the early-style Twin Cam 96 crankcase.
- 2007-2016 Touring 585 Cam variations fit 2007-2016 Touring with the oil-cooled Twin Cam 96 or 103 engine.
- Excludes all Softail platforms and all Twin-Cooled Milwaukee-Eight configurations.
- Long-block scope: the installer retains the existing Twin Cam chassis crankcase and supplies the throttle body, intake, exhaust, and ECM tune; the new 111 displacement requires a calibration flash.
- Refer to the Fitment tab for the full platform breakdown per variation.
