Ram Power Wagon
This is what happens when you shorten up a standard Power Wagon Heavy Duty pickup, and trade stock 31-inch tires for 40-inch rubber. Instead of a 148-inch-wheelbase Crew Cab, the Powerwagon concept shown here is 120 inches from axle to axle, and it seats two.
It keeps the standard Power Wagon 4.56:1 axle ratio and the 5.7 Hemi, but adds a four-link coil spring rear suspension from a Ram 1500 to greatly enhance suspension travel. A four-inch lift and careful fender and bumper design allow the 40-inch rubber to fit, just barely, making the Powerwagon concept about four inches taller, four inches wider, with an estimated 16 inches of ground clearance. The spare tire was moved into the stepside bed, where it takes up most of the space. Body protection includes sill guards and custom bumpers on both ends by Rock-Slide Engineering.
Given that the Hemi makes 400 pound-feet of torque, and low range gearing is 2.72:1, the Powerwagon concept still had plenty of crawling power on the rocks at Moab...and ground clearance to burn.
