Cummins 4BT
Parts and Accessories

The 4BT Engine is a very common motor to use on custom truck and SUV engine swaps. People often will swap it into Jeep Wranglers, Gran Cherokees, Chevy Blazers, Land Rovers and other SUVs.

It is the little brother to the 6BT found in Dodge Rams. It is a very strong motor that is capable of handing 500+ RWHP with supporting modifications. The motor is often removed from Bread Trucks/Commercial Vans and other smaller around the town hauling trucks.  It is also sought after because you can get extremely good fuel economy out of it, 40+ in some cases.

At Diesel Power Products we are currently working on 4BT build ups 2 Jeep Wranglers. The first was finished and debuted at the 2012 Easter Jeep Safari in Moab, UT. Diesel Power Products is the Bruiser Diesel Conversion headquarters for the west coast.
