Taking a stock monster and making it scarier is tricky business. Exodus 4×4 recently showed off a build that turns the volume up on the Jeep Wrangler 392 Hemi without wrecking what makes it great. Bubba Bryan walked through a mod list that transforms this V8 Wrangler into a towering, supercharged beast that still drives with the manners of a factory rig.

Elevation Without Compromise

The first thing you notice is the height. This Jeep Wrangler 392 Hemi sits on massive 40-inch Nitto Trail Grapplers, thanks to a set of Gen I portal axles from 74 Weld. This gear gives the truck huge ground clearance and width without messing up the factory suspension geometry. Bryan made the drivability clear and stated, “This thing still drives and handles basically like it was stock.” By keeping the original springs, shocks, and steering parts, the ride quality stays smooth even with the aggressive lift.

Clean Exterior Upgrades

To cover those giant tires, Exodus 4×4 skipped the bulky aftermarket flares and went with a Quake LED fender trim kit that keeps the painted factory look intact. Underneath, American Adventure Lab inner liners clean up the wheel wells with their simple cam-lock fasteners. Practicality is key here, too, with Rock Slide Engineering power steps making it easy to climb in and a Motobilt tire carrier handling the heavy spare. It’s a build that follows Bryan’s philosophy: “It does all the right things without doing too much to the Jeep.”

Supercharging The Jeep Wrangler 392 Hemi

The real party piece is under the hood. A Whipple supercharger, custom powder-coated gold to match the Jeep’s trim, sits on top of the 6.4-liter engine. The stock pistons limit the boost to about 6 psi, but the power gain is serious. Bryan compared it to engine surgery and said, “I would say it’s equivalent to putting a cam swap in there.” The portal axles actually help the drivetrain handle this extra grunt by distributing the torque load, keeping the axles from snapping under stress.

A Cohesive And Capable Build

Finishing off the build is an American Adventure Lab tailgate system packed with an ARB compressor and Apex hose reel, making it trail-ready. The whole package is aggressive but incredibly clean. Bryan summed it up best: “It’s an aggressive looking Jeep that didn’t take a whole lot of like we didn’t have to change a whole lot about the Jeep to make it look this way.” It’s proof that you can build a monster without losing the Jeep’s soul.
