MBRP Performance Exhaust (and its Jeep-specific subsidiary Off Camber Fabrications) manufactures high-end exhaust systems as well as a variety of different Jeep parts including roof racks, light mounts, cargo baskets, armor, and bumpers. Somebody at the company came up with the fantastic idea of shoehorning a 12-valve Cummins Turbodiesel into a stretched Jeep Wrangler JK pickup conversion and fully outfitting it with offroad equipment. Including portal axles and 44-inch Pitbull Rocker tires.
The end result was a real monster. The extra-long wheelbase and the tremendous weight of the Cummins motor over the front axle allow this Jeep to climb incredible obstacles with unreal ease.
