Ultima El Bruto 113ci Natural Complete Driveline Open Belt Primary 6 Speed Transmission

Ultima's commitment to engineering excellence and competitive pricing brought El Bruto to life with a completely new design set of castings emphasizing performance, reliability, and value.

All of the castings in these Engines are poured in US foundries and are based on all new CAD designs cast from C355 aluminum, a common US military alloy known for its stability over multiple heat cycles. The engine components are machined on state of the art CNC equipment for guaranteed dimensional accuracy and repeatability.

Ultima’s carburetors are directly interchangeable with S&S Super G carburetors. They will accept S&S jets and S&S bolt pattern air filter assemblies. The relocated accelerator pump nozzle has increased throttle response and thunder jets are bolt on. Simply remove the plugs and screw in the Thunder Jet. No expensive machining required.

Freeway cruising becomes more enjoyable with reduced vibration, increased gas mileage while keeping the engine in the heart of its torque band. The 6-speed transmission is complete, and ready-to-install

Fits Harley Davidson Softail frames and custom application.
