1978 Ford Bronco - Black Stallion

Posted in Features on October 21, 2013

The affectionately named Big Broncos were only made for the ’78 and ’79 model years on the heels of Ford’s classic Early Bronco. Big Broncos have created a cult following of their own though, with V-8 engines, strong axles, and excellent suspension, but without the price tag associated with Early Broncos.

Kevin Koehn and his brothers took a Big Bronco and made it even bigger, with 1-ton axles, a stretched wheelbase, and huge 44-inch Pit Bull Rocker tires. The bigger body also provides plenty of room for Kevin and his whole family to get out and hit the trail, whether they are wheeling near their home in British Columbia or taking a road trip to Johnson Valley, where we caught up with him.
