There’s no replacement for displacement, and that means more cubic inches. Stage III upgrades add size to your engine and increases compression for a bigger bang. With the proper cam profile and free-flowing intake and exhaust, a big-bore motor can be tuned to deliver the power to ride any way you like or the power to ride two up, and feel like you’re solo.
This upgrade requires removing the engine’s top end and swapping the cam. The engine remains in the chassis and no machining or custom fitting is required.
Special tools and ECM tuning are required.
| Engine | Upgrade Capacity | Part Number |
| Twin Cam | 107CI to 110CI | 92500035 |
| Milwaukee-EIght | 114/117CI to 122CI | 92500086 |
| Milwaukee-Eight | 117CI to 122CI | 92500139 |

This Stage III kit has been developed to deliver the kind of real-world power increase Touring riders will feel each time they roll on the throttle. The bump up in displacement and compression paired with a Screamin’ Eagle® SE8-511 camshaft deliver a significant increase in torque and power over stock and may restore the sensation of riding solo when you’re loaded down with a passenger and gear.
