After we delivered the '07 JK to American Expedition Vehicles, we began measuring the giant Cummins 24-valve, common-rail, 5.9L diesel engine and of course found it to be much larger than the factory '07 Jeep 3.8L V-6. The Cummins weighs around 1,100 pounds and is nearly 3 feet tall, 3 feet long, and 3 feet wide, so the project of stuffing that engine into the Jeep frame was going to be an uphill battle. However, the Jeep frame is no weenie frame as in olden days. In fact, its fully boxed chassis is made of tubing 2 3/8 inches wide by 5 1/4 inches tall-bigger than some 1/2-ton trucks we've seen.
