Beware the words "just one more." James "Slim" Janssen can tell you why. Not so long ago, the blue F-250 on these pages was glimmering white. During a long weekend in the desert, yours truly was en route from another corner of the Mojave, planning to meet Slim and the rest of the Mojave Mafia for a few hours of photo shoot fun. James and crew had spent most of the afternoon playing in the whoops and turns near the Slash X Café in Stoddard Valley. It was time to give the truck a wipe-down. Before parking, the proud owner cranked the wheel and hit the throttle in the name of "just one more" powerslide. Mid-slide, the outside rear tire blew off its bead, hooking the wheel in terra firma, and sending the truck rubber-side up. Oops.

1973 Ford F 250 Three Sol Teck Hid Lights
Keith Sato built the front bumper that leads the way. Three Sol Tek HID lights make after-dark desert running an option. Trailer Products was responsible for the dropped center hood and mildly-flared fenders. Five Autofab hood pins keep things secure through the rough.
James bought the truck already built, and the original build used bolt-on roll cage and suspension construction. Even though he ended up redoing most of the build, new 'cage and suspension components were still bolted to the frame rather than welded directly on. Bolt-on construction takes more time during the initial build. Instead of welding directly to the frame, landing plates are made to bolt on. This means spending time making the landing plates, and spending time drilling holes in the frame to mount them. Once the plates are bolted in place, rollcage tubing can "land" on the plates. This method also applies to leaf spring hangers, bump stop mounts, and radius arm brackets.

A set of Trailer Products bedsides partially camouflage the suspension and structural upgrades behind them. James didn't skimp on the Dzus tabs: nine per side do a great job of keeping the bedsides in place.
The front suspension is classic and simple. Kingpin-style I-beams were slightly extended and then plated in for maximum strength. The rear-steer knuckles were retained, along with the OEM-configuration steering linkage. Tony Sato built James a set of billet front hubs which are lighter and stronger than the '73 pieces. The early '90s flavor comes from the coil bucket-mounted springs and the dual smooth-body Fox 2.0 shocks. A Fox bumpstop on each side updates the performance during hard hits.

1973 Ford F 250 Engine
The big 400 breathes through a UNI filter, and is cooled by an all-aluminum PWR radiator. James built the radiator hold-down bracketry. Chrome won't get you home, but it admittedly looks nice on the engine cage's cross-brace. Note the engine bay light: all the better for after-sundown repairs.
Out back, the bolt-on leaf spring hangers and matching bolt-on shackle brackets are home to a pair of Deaver leaf packs that mount to the top of a Currie-built Ford 9-inch rearend. James wanted to use the same old-school shock setup that the front end had, but found it impossible to achieve the same control using smooth-body shocks. Shock tuning on both ends comes courtesy of Keith Sato, who is Tony's brother and a fellow Mojave Mafia member.

A PWR tranny cooler controls the temperature inside the C6. Note the through-bolt plates that connect the bed 'cage with the cab 'cage. This construction made the job easier when the cab had to be replaced. Friends Keith and Doug get special props from James for their help in replacing the cab. Finally, there's a rear-facing amber light on the far right. Amber lights keep you safer in the dust whether you're racing or not.

1973 Ford F 250 Factory Steering Linkage
The original '73 steering linkage still runs behind the kingpin I-beams, albeit with some strengthening and lengthening. In this location, the steering linkage is well-protected. The lack of bends in the tie rods adds to the longevity of this linkage.

Did we mention everything bolts on? Note the slick little protector for the brake line's frame mount. There are 16 inches of travel on tap.
