Here's what Chrysler says about the Mighty FC: To create the Jeep Mighty FC concept, the design team started with a 2012 Wrangler Rubicon and repositioned the cabin over and ahead of the front axle, lengthened the wheelbase, and added a custom built drop-side cargo box. The cab utilizes a roof from the Mopar JK-8 conversion kit, as well as a custom-designed front clip. The Wrangler-based interior has been enhanced with bold, heavy-duty Katzkin leather and a unique color scheme. The cargo area is handled by a full-width, drop-side tray-style bed that measures more than eight feet in length. Off-road function is dramatically improved with the addition of Mopar’s new Portal Axle set. These offset axles offer the greatest amount of ground clearance without requiring excessive suspension lift. Mopar’s Front Portal Axle (8-lug, part number P5155670) is available at a Manufacturer’s Suggested Retail Price (MSRP) of $12,500, and the Rear Portal Axle’s (8-lug, part number P5155671) MSRP is $11,000. The axles are controlled with King coil-over assemblies along with beefy Teraflex control arms and track bars. Traction is handled by massive 40-inch tires mounted on custom Hutchinson 17-inch beadlock wheels. Other Jeep Mighty FC highlights include King coil-over reservoir shocks, Hanson bumpers, a Warn 16.5 winch and a Corsa stainless steel exhaust system.

Chrysler's site describes the J-12: The Jeep J-12 concept is essentially an extended version of Mopar’s recently introduced JK-8 pickup conversion kit for the Jeep Wrangler. With a new 2012 Wrangler Unlimited as the starting point, the rear of the vehicle’s frame is extended 18 inches, allowing the spare tire to be relocated under the bed floor and making the cargo box a full six feet in length. A custom hood and front fender set was created as a nod to aficionados of the beloved Jeep Gladiator series trucks. Off-road muscle has been improved with the addition of the new Mopar three-inch suspension lift kit, as well as Teraflex sway bars controlling ARB air-locker equipped Dynatrac D-44 and D-60 axle assemblies. Traction is handled through classic 36-inch tires mounted on 16-inch steel wheels. The cabin of the J-12 concept has been “dressed down” in support of a basic truck theme, with the carpet being replaced by rugged truck bed liner, and the bucket seats re-crafted into a modern version of a bench seat, trimmed in white with a whimsical plaid pattern. Further highlights include a Mopar fuel-filler door, Mopar slush mats, Tom Woods custom driveshafts and Katzkin seat trim.

Chrysler describes the Traildozer: To prepare the Jeep Wrangler Traildozer for Moab’s toughest trails, Jeep Design worked closely with the American Expedition Vehicles (AEV) engineering team to bring it to life. Starting with a new Dozer Yellow 2012 Jeep Wrangler Rubicon, the team added a bolt-in 470 horsepower 6.4-liter HEMI V-8 engine mated to a Getrag 238 six-speed manual transmission. Power runs through Rubicon-specific Dana 44 axles equipped with 4:10 gears and electronic locking differentials. To clear the 37-inch Mickey Thompson Baja Claw radials mounted on Mopar Classic five-spoke wheels, an AEV Dualsport RS 3.5-inch suspension lift was installed. For severe off-road body protection, Mopar premium front and rear bumpers and rear corner guards were added. Additional items include a Mopar performance heat reduction hood, Mopar half-door kit and a Mopar/Warn 9.5 Cti winch. Jeep Wrangler Traildozer’s interior includes an AEV ‘F-1’ leather seat trim kit and Mopar slush mats.
