Chrysler Group have unveiled the production-version of the 2004 Dodge Ram SRT-10 during the truck's world debut at the 2003 Chicago Auto Show. Producing 500 horsepower and 525 lb.-ft. of torque from the 8.3-litre V-10 engine that powers the legendary Dodge Viper, the 2004 Dodge Ram SRT-10 is the most powerful production pickup truck ever, according to Chrysler.

The Ram SRT-10 features the largest standard wheels and tires, plus the largest brakes in its class.

The new Ram goes on sale in the US late this year.
