A Rockwell 20-145 routes power to the rear 15x18-inch Real Racing Wheels and 34-inch Nichols Pulling
Edge tires. Its aluminum center section was made by Advanced Chassis and conceals a spool and 6.17 gears.
The components required for Will to build the A-frame style hitch arrangement were supplied by the folks at
Proformance Pros.Starting with a ’16 frame, Will set to work reinforcing the front
section to handle 2,000 pounds worth of hanging, bouncing weight by
bracing and then boxing it in. He then turned his attention to building the
subframe, which spreads the load from the rear axle across the frame,
toward the front of the truck. For optimum strength, the subframe was
built using a triangular pattern, and from thick wall round tubing. For a
clean overall look, Will even filled some 219 holes (per rail) in the factory
frame prior to treating it to its matte black finish.
Up front, a Rockwell F106 fitted with a Detroit locker takes care of business, with forward bite being aided by a four-link suspension system. A pair of coilover shocks on each side allow
for suspension preload adjustments to be made based on track conditions. Maneuvering the truck around comes easy thanks to a full hydraulic steering system from PSC Motorsports.A team effort in every sense of the word, Ferenc told us “we all have our roles.” Nate is the driver, Will is the
builder and mechanic, and Ferenc is in charge of all logistics and making the lives of the other two easier by
being prepared. “During the build process, I tried to stay two weeks ahead of Will in keeping him supplied with
parts to add to the truck.”Driveline & Suspension
Getting as much of the engine’s 1,800 flywheel horsepower
to the Nichols cut tires begins with a four-disc Crower clutch
inside a Custom Floaters bellhousing. From there, a Quick
Change transfer case and Reverser combination from Pro
Fab Machine transmits power to both axles. As for axles,
the familiar 20-145 Rockwell can be found out back, while
a Rockwell F106 resides up front. There is no suspension
to speak of in the rear of the truck, but the front suspension
incorporates a four-link system with a pair of adjustable
coilover shocks on either side of the axle.Only the Beginning
After a full season with zero issues or breakage in 2018 and
plans to do the same in 2019, the Jumping Jack Flash crew
are definitely happy with how the truck turned out. But don’t
confuse happy with content. Ferenc, Nate, and Will plan to
continue accumulating data, seat time, and tweaking the
truck’s setup until their Ford runs at the front of the pack.
With plans to hook with PPL all summer—along with select
NTPA, Xcaliber, and Full Pull Productions events (and even
a return trip to the National Farm Machinery Show this win-
ter)—they’re keeping a busy schedule on purpose. Sooner or
later, they could be knocking on the doors of the best trucks
in the business.JUMPING JACK FLASH
