48RE Suspension PVO engineers modified the Ram Heavy Duty's rack and pinion steering and independent front suspension for use in the Ram SRT-10. A fully hydroformed Dodge Ram frame was used in conjunction with a custom-tuned suspension, lowering the Ram SRT-10's ride height one inch in the front and 2.5 inches in the rear. Bilstein shock absorbers, performance-tuned springs and unique aerodynamic aids were used to enhance the Ram SRT-10's higher-speed performance. An additional 5th shock was used on the rear axle to prevent wheel hop during wheel-spin. Exterior The Ram SRT-10 had a unique hood that featured a wide power bulge and honeycomb grill hood scoop. The hood scoop allowed cool air to enter as well as forcing hot air to exit from the engine bay, thus helping the engine to run cooler. "Viper Powered" badges were added to the sides of the power bulge, to indicate the SRT-10 engine under the hood. Large chrome SRT-10 logos were mounted to the driver and passenger side doors and rear tailgate right side on the Quad cab and Single Cab 2005 models replaced in 2006 by smaller chrome and red SRT-10 logo badges . All models were outfitted with large molded kickerpanels painted to match body color. Another exterior feature was a tonneau cover with an attached spoiler that was supposed to come standard on the 2005 Quad Cab version and all 2006 models, but due to manufacturing problems was not installed on nearly half of the Ram SRT-10s intended. To help remedy this situation, Dodge added a $1000 credit and a regular spoiler to the Ram SRT-10s that did not receive the tonneau cover. In addition to style, the spoiler also helped with air flow and provided a reduction in lift and drag. The Ram SRT-10 had a bed size of , giving the regular cab an overall length of , and overall length for the Quad Cab. Interior The Truck audio had 3 options of the Dodge Ram SRT-10 by 2006 and consisted of 8 Infinity brand speakers with a DVD based large color LCD map navigation system and a mid-tier CD turn by turn graphics CD-based system with small color LCD, and finally a standard LED Radio with CD player; all built and designed by Infinity audio and 10 inch woofer mounted in between the seats with silver bezel and 575 watts of total system output, Bluetooth by
