THE SCIENTISTS OF LIGHTING
Pettus, the Dana 60 and its respective coil spring, radius arm front suspension was underneath the truck in two days’ time. While most of the steering components from the ’08 donor swapped over, an ’05 steering box was sourced and an adjustable track bar from BD Diesel was added. An ’08 rear Sterling 10.5 and leaf springs would also be installed, replacing the factory 10.25 unit. Thanks to the Super Duty axles and top-of-the-line performance parts, Andy Inman has effectively ushered his ultra-clean OBS into the modern age—an era where ride comfort and big horsepower go hand-in-hand.
In the process of combining old school looks with a plusher ride and respectable horsepower, Inman managed to build a work of art that’s also a blast to drive. And given that Inman performed all the work at his own facility, Andy’s Garage in Park Hills, Missouri, he has the satisfaction of saying the truck is owner-built.
Also sourced from an ’08 Super Duty, a 10.5 Sterling replaced the factory 10.25 axle out back, along with its respective leaf springs. To achieve the stance Inman was after, 3-inch blocks are utilized. Also notice the Ford Bronco tank, which allowed him to do away with the factory saddle tanks and (more importantly) the restrictive fuel selector valve when it came time to run the aforementioned high-flow fuel supply system from Irate Diesel Performance.
While the 10.5-inch ring gear Sterling axle was a slight upgrade over the factory 10.25 unit, Inman knew it would still be susceptible to torrential axle wrap with the power he planned to make. To keep the axle from rotating and the leaf springs from twisting, he had nearby Tube Works Fabrication in Desloge, Missouri, build a set of stout traction bars. The bars attach to both the frame and axle via welds.
