Once the truck was returned, it was an instant thrash to make the SEMA deadline. The front suspension received Air Ride Technologies pneumatic 'bags and hardware with Air Ride nitrogen shocks. The rear suspension was anchored with an Air Ride four-link pivotal latitude system and a Panhard bar, which eliminates any lateral movement, and when combined with Air Ride pneumatic 'bags, it contributes to the rear suspension agility. The pneumatic suspension system is activated with the flip of a switch. To decelerate the mighty Hemi power, a pair of U.S. Brakes with 15-inch rotors and massive four-puck calipers was bolted in up front. A spinning set of Colorado Customs 22x9-inch polished billet aluminum spools are wrapped with P305/45R22 Toyo rubber.
The '03 345ci Hemi 5.7L engine is a redesign of the earlier Hemi engines of decades ago. These were deep-skirted cast-iron blocks with cross-bolt main bearing caps and cylinders with a 3.93-inch-diameter bore and 3.58-inch stroke. Lighter aluminum alloy cylinder heads use a unique hemispherical dome; the pushrod design uses 16 valves, hydraulic lifters, and roller rockers. A sequential multi-port, electronic fuel-injection system delivers fuel to hemispherical combustion chambers that develop a 9.6:1 compression ratio. The Hemi creates 345 hp at 5,400 rpm and 375 lb-ft of torque at 4,200 rpm. At 5,800 rpm, the rev limiter allows for maximum peak engine performance but attains its potential energy. As it enters the ATI ProCharger inter-cooled Hemi supercharger, an AIRAID intake system increases the airflow velocity with fewer restrictions, creating 7 pounds of boost. An NX system with a 100 shot of nitrous oxide makes for instant neck-snapping excitement. On the other end of the horsepower equation, a set of ceramic-coated Dynatech long-tube headers link up to the MBRP 3-inch exhaust tube voiding the spent gases. For a more responsive bottom-end and quicker shift points, a stock Dana rearend is set up with Richmond 4.10 gears.
