This concept Wrangler, which the Mopar team calls ImMortal, rides on prototype Mopar portal axles, allowing the axle tube to be located well above the wheel hubs. In this case, the five-inch ground-clearance gain allows the use of huge tires without the need for massive lift.
Coil springs and Bilstein shocks allow the axles to move around, but this Jeep's capability is based more on ground clearance and gearing than extreme articulation. The portal axle ends contain their own reduction gears, which combine with a 4:1 transfer case for a super-low, 100-to-1 crawl ratio. Not-for-highway-use, 42-inch Goodyear MTR Kevlar tires on 17-inch beadlocked wheels add still more ground clearance.

Most of the parts here will be available through Mopar: axles, two-inch lift, body armor, heat reduction hood, half door kit, sun bonnet, and seat covers. The body armor includes a front brush protector and strong, compact rock rails. Using an AEV swap kit, a 5.7-liter HEMI V-8 was installed to replace the stock JK 3.8 six. To handle the large tires hydraulic steering assist had to be worked out, and custom Tom Woods driveshafts were needed as part of the engine swap.
Custom bumpers are used front and rear, with a Warn winch mounted up front. Wide tube-and-panel fender covers house the 42-inch rubber. Viper Snakeskin Green Pearlcoat paint covers the new bodywork; Katzkin leather seats upgrade the interior.
