JB Custom Fabrication Unleashed The Baddest Pony In The Herd

From the creative minds of JB Custom Fabrication comes another innovative Bronco build out of their shop in Salem, Oregon. The Bad Pony Ford Bronco is the latest of those that come out of the shop owned by Jon and Rhonda Barricklow. This appropriately named 1974 half-cab Bronco was built to be completely capable off-road, and easy to drive on road.

The Barricklows were the couple that built two previous Broncos with Cummins Diesel engines implanted into the engine bay. The Grey Goose and the Heavy Horse have been extensively featured in many other off-road publications. At the urging of his wife Rhonda, Jon even built a Bronco Trail-er from the rear half of an original half cab.

In 1995 Jon Barricklow left his job at a chemical company after 21 years and started a business concentrating on single, double, and triple transfer case cable shifters and custom shifter boots, and machined shifter knobs. Rhonda is experienced in paint and bodywork.  From those humble beginnings and concentrating on quality products instead of a cornucopia of different parts Jon and Rhonda have built a great business.

The One Bad Pony Ford Bronco Build

Each of Barricklow’s previous builds was designed to turn heads at a distance with some outrageous customizing. This time they went for stealth trying to hide the magic under a very bold coat of orange paint and a slightly massaged body. Going across the dunes on the Oregon Coast you would not take much notice until the throttle opened, or the suspension started gobbling up the dunes. Here are the customizations that make One Bad Pony… well, one bad pony.

The Bad Pony Body

Jon started with a stock factory frame which he modified. Mounted on top of the frame is a Dennis Carpenter steel replacement body, also heavily modified. Jeff’s Bronco Graveyard supplied heavy-duty front fenders.  Rhonda worked over the body and fenders to her liking before sending it off to get some color. The Go Mango and black satin finishes were applied by Todd Hollis Auto Body.

The Suspension, Steering, and Axles

The heavily modified frame was built to support a sophisticated four-link suspension. The front features parallel four links with a Panhard bar. The bumps are soaked up by an ORI 12-inch front strut and Fox four-inch nitrogen bump stops. In the rear, a double-triangulated four-link system supports a 14-inch ORI strut assembly. All the struts have oil reservoirs attached to help cool the units when the going gets rough.

Steering is handled through a Wild Horses box with a hydraulic assist to make it easier to move the 35-inch-tall Goodyear Wrangler tires wrapped around DOT-legal Hutchinson double bead lock wheels.

As any Bronco owner will tell you the axle assemblies need a lot of upgrades if you plan on doing some extreme wheeling. Jon did not mess around and went straight to Ford nine-inch units heavily fortified by RuffStuff Specialties.

In the front, the nine-inch features a Strange Nodular center section with 35 spline Dutchman axles turned by Tru-Track 4.86 gears. Solid Axle Industries knuckles, Dana 60 outers, and Teraflex hubs take the brunt of Jon and Rhonda’s abuse at the wheel end of the housing.

The rear is much like the front except the 4.86 gear is a Wavetrack setup. The axles ride in Dana 60 full floater outers.

Bad Pony Ford Bronco Engine

One Bad Pony’s mighty power plant is based on a 427 cubic inch Dart SHP iron block. The rotating parts are supplied by Scat in the form of a forged crank and H beam rods which push the Ross 8.9:1 compression pistons.

Sitting on top of the block are Dart Pro1 aluminum heads held securely to the block with ARP head studs. The valve train glides along a Bullet custom ground camshaft via Scorpion roller rockers and studs.

Fuel feeds through a FiTech Go EFI-8 1200hp Power Adder Plus into an Edelbrock Performer RPM intake manifold. That is a lot of fuel system but consider that Jon and Rhonda do not like to miss out on horsepower so there is a Precision T-3 turbocharger shoving ridiculous amounts of air into the engine through a JB Custom Fabrication air charger and plenum. The fuel and air are ignited via a MSD Billet distributor and ignition system.

The exhaust is all custom built in-house at JB Custom and you will not find any mufflers on this vehicle.

All the horsepower means a lot of heat, so cooling is important. Jon turned to an Edelbrock water pump and a Ron Davis dual-pass radiator. Engine oil cooling is handled with a Derale oil cooler. All the critical drivetrain information is relayed to the custom dashboard via Speedhut gauges.

Bad Pony Ford Bronco Transmission

The Bad Pony horsepower is routed through a Ford 4R100 transmission with a stage four upgrade. A Billet torque converter handles the transfer of power between the engine and transmission. An HGM shift controller runs the electronics that boost the hydraulic pressures. A RADesigns shifter selects the gears that they need.

An Atlas Pro Case transfer case is hooked up to a JB Custom twin-stick cable shifter. The power then is distributed and sent front and rear via Tom Woods driveshafts hooked to 1350 CVs. What it all means, in the end, is the Bad Pony Bronco has as bulletproof a drivetrain as possible. With this setup, whether they are in the Oregon Dunes or the deserts of eastern Oregon, One Bad Pony can handle whatever they throw at it.

Finishing Touches

Comfort and aesthetics are maintained while roughing it out on the trails and dunes. Seats were supplied from Tom’s Off Road and Simpson Race Products safety harnesses hold Jon and Rhonda in place no matter how crazy it gets out there.

JB Custom Fabrication built their own bumpers, front, and rear. They also built their own half-cab custom roll cage and fitted their own custom-made half-cab cover which mounts in six locations.

There is enough auxiliary lighting mounted on One Bad Pony to light up the night on any dune or trail courtesy of Rigid and Lux. From the sounds of all these amazing modifications, there is not much of anywhere that this machine cannot go.

Look for One Bad Pony at a Bronco gathering in the Pacific Northwest and other areas.
