• Jeff Daniel’s Jeep Customizing has designed and manufactures the components necessary to swap a 4BT Cummins Diesel engine into your CJ, YJ, or TJ Jeep (1976-2006). WE ARE NOW CONVERTING JK'S TOO! (2007-20012)
• In order to properly convert your Jeep we will need to know a few things about your 4BT and about your Jeep. Please be sure and fill out the questionnaire and follow the instructions on the last page.
• The swap will yield you better fuel economy, better torque for off-road and towing, longer life of the Jeep, and lots of looks on the street!
• We use 4BT Cummins engines for our swaps., and recommend the AX-15 transmission or an NV4500 also works well. 3.07 gears with 33” tires will get you the best fuel economy. You can also use a TH400, TH700R4, or Ford AOD if you prefer an automatic. (may require modification)
• Your jeep will also need 4” of lift in order to fit the 4BT inside the engine compartment.
• This swap will take about 60 hours to complete.
• Basic mechanical ability as well as basic shop tools are required.
• Engine and Transmission are not included in our kits, if you cannot locate your own contact Jeff Daniel’s and we will be glad to help.
• The parts listed on the following pages can be purchased as a kit or a-la- cart.
• If you have a TJ (97-06) and wish to use your A/C, you MUST have a Ford style 4BT, a CJ seiers Jeep requires a Ford as well to accomadate the driveshaft.
• Certain components are only needed on certain model Jeeps.
• Check with your State's Department of Transportation on how to re-register your vehicle as a diesel. This is required by states with inspection/emission laws.
