Powered by SRT = Dodge’s Engineering Team

“Powered by SRT” means that the engine was specially designed by Dodge’s Street and Racing Technology (SRT) team. This team is dedicated to producing and perfecting Dodge’s line of performance models. They are responsible for the 6.4L SRT engine, the 6.2L SRT Hellcat engine and the 8.4L V10 engine on the Dodge Viper.



If you are considering a HEMI conversion for your Jeep, you have come to the right place.
We have countless Jeeps running the street, off road parks, and alike sporting a 6.4L HEMI and enjoying REAL V8 power and better gas mileage to boot. These HEMI engines don't have to work nearly as hard as a V6 to pull their weight around, not to mention towing a boat or utility trailer. We have a time tested and proven process for converting your Jeep over to this awesome platform and we would love to talk to you more about it.
We stand behind our work.
