The Cummins 4BT turbo diesel is the perfect option for the Jeep enthusiast looking to improve their fuel efficiency and off-road capability. In addition to boasting increased fuel efficiency, the 4BT is also capable of running alternative fuel sources like Waste Vegetable Oil (WVO). 2007 - 2011 Jeep Wrangler can be converted.


The Cummins 4BT is one of the most proven diesel engines in the world. If well maintained, one can expect to get 300,000 miles out of their engine with 500,000 miles not being uncommon. Our standard conversion includes a rebuilt Cummins 4BT with the option of using a used or rebuilt model if the client prefers.


The stock transmission must be replaced as part of the 4BT conversion. Customers have the option of a 4l80e HD automatic transmission or NV4500 manual transmission.
