The Original MegaRexx® - General Information

The key to a great all-around off-road truck is to RAISE the axles and differentials with larger tires so they clear rocks, snow, mud, and other obstacles. The larger diameter tires we use are also wider than stock, which helps to prevent the tires from sinking into soft terrain. Our proprietary, computer-aided design (CAD) body modifications allow the use of larger tires with little lift which helps to keep the center of gravity down low for increased stability, which is further enhanced by the much wider track!

Original MegaRexx® conversions begin with a teardown of the entire front clip, removal of the bedsides, installing the 4" lift to level the truck, and installing longer shocks on the front and rear.

Our Stage 1 conversion package includes all fiberglass parts, the steel halo that supports the hood and lights, the links for the tilt mechanism, headlights, tail lights, grill, amber or white lights for the grill, gas shocks that help lift and hold the hood open, and the necessary parts to facilitate the larger wheel and tire combination. When you discuss your specific needs with us, we will price your options and current costs for those items. The Stage 1 conversion package also includes color-matched paint for your truck completed by our talented in-house body & paint team. Two-tone paint schemes, pearls, and complete repaints are additional.

The Original MegaRexx® Stage 1 conversion package also includes moving the front axle forward 1.5" to allow the larger tires to clear the firewall. We designed a super-strong steel halo used on the front of the truck to support the slick one-piece tilting hood, headlights, and grill. The hood is held closed by internal rubber lockdowns, the same used on Freightliner semi trucks — easy to snap down and hidden from view.

​Every component is hand-fitted with close attention to detail, fit, and finish. The rear bedsides are bolted to the frame with stainless steel nuts and bolts. The undersides of the fenders are undercoated. Galvanized 3/4" steel struts secure the outer fenders — just like the original truck, but much heavier.

Once the Original MegaRexx® body conversion is complete, the nitrogen gas shocks are added to support the tilt hood when open. The windshield washer squirters are added onto the wiper arms. The front cowl is trimmed to fit the hood with a close fit. The radio whip attached to the right front hood hinge is kept in place by trimming the hinge and retaining the antenna support. 


Original MegaRexx® fenders and hoods have 3" of the wheel well removed to allow fitment of the larger wheel and tire combination. The hand-laid fiberglass process we utilize is so thick in these areas that no additional modifications are required. There is no lip or return to allow mud, snow, and sand to fall off the wheel wells easily.

Once back from our in-house paint shop, the hardware for the hood and fenders is replaced with anodized aluminum parts. We use Anzo Switchback headlamps which are white around the edges and glow amber when the turn signals are activated. Lastly, the wheels and tires are installed. The truck is road-tested and adjusted.

Original MegaRexx® rely on the reliable power of Ford F-Series Super Duty trucks equipped with the 6.7L Power Stroke® V8 Turbo Diesel. The Original MegaRexx® needs the power and torque of the turbo-diesel to accommodate the larger 46" x 15.5" Michelin XZL (395/85R20) tires mounted on MRAP (Mine-Resistant Ambush Protected) aluminum wheels. These are the current wheels and tires fitted to military FMTV and other larger vehicles. To ensure proper acceleration and retain the towing ability, we re-gear the axles with 4.88:1 gears.

The MRAP wheels are rated at 10,000 lbs each and the tires are G-rated, so weight is no issue for an Original MegaRexx®. The wheels are disassembled, cleaned, sanded, and repainted. The 46" Michelin XZL tires are professionally mounted and balanced for smooth operation on the highway on a special machine designed by Hunter exclusively for large radial tires. ​We also correct the speedometer via our calibration programmer for each truck, made by Hypertech, and all builds include this unit.

There are endless options available for an Original MegaRexx® – push bumpers, desert or pre-runner style bumpers, deer guards, electric side steps from Amp Research, spare tire carriers, front and/or rear winch, high-end EBC brakes, custom exhaust, off-road lights, work lamps, power inverters, etc. – whatever you can dream, we can build!

The final cost of your Original MegaRexx® is determined by your specific needs. Every truck is a true one-off, custom build – no two trucks are identical. We'll start with the Stage 1 conversion, add your options, and we'll estimate the cost of your build prior to your order so there are no surprise cost overruns.

​During the build, you can add/delete/modify items to your build via a change order. Simply send us a request by email, and we will send back a written change order with the associated cost or credit. ALL change orders must be in writing. Sure, we can discuss them over the phone, but the actual change order must be in writing which will include any changes in the total cost of the build. We reserve the right to change prices based on changes from our suppliers, but once we send you a quote (good for 10 days) your prices are guaranteed. A typical conversion takes about 4-6 weeks, however, due to high demand, it may take a month or more before we have a built slot available.

​If you want a GENUINE F250, F350, or F450 Original MegaRexx®, THIS is the ONE AND ONLY place to get your hands on one!
