Under the hood lurks a Grand Cherokee 5.2L V-8. The engine internals remain mostly stock, but it has been fitted with a performance-inspiring Pro Charger supercharger. This helps the engine spew an estimated 350 hp and 350 lb-ft of torque. Other underhood mods include an engine-driven air compressor, a pair of Blue Top Optima batteries, 2.5-inch exhaust, and a 40-Series Flowmaster muffler. Nestled behind the engine are a trail-proven NV4500 transmission and a crawl-happy Atlas II 4.3:1 transfer case.
