On Feb. 2, 2004 an unmodified 500-horsepower, Viper-powered Dodge Ram SRT-10 earned a spot in the Guinness Book of World Records as the world’s fastest production pickup truck with a measured top speed of 154.587 mph (248.783 kph) sustained over a flying kilometer. Not only is it fast, the Ram SRT-10 is also quick, with 0-60 mph times in the low five-second range.

For 2005 Dodge Truck Enthusiasts now have two choices of the boldest, most outrageous pickups ever sold. The Dodge Ram SRT-10 and SRT-10 Quad Cab both feature a 8.3-liter (505 cu. in.) Viper V-10 engine making 500 horsepower (372 kW) and 525 lb.-ft. (712 N•m) of torque. The Dodge Ram SRT-10 Regular Cab is still the logical choice for the performance truck enthusiast who would rather see a clutch pedal than two extra doors in the boldest, baddest pickup on the planet.
 
The Ram SRT-10 puts its V-10 to work through a T-56 six-speed manual transmission fitted with a Hurst shifter. For 2005, a new drivetrain enhancement has been added to further help get that power to the road: The Ram SRT-10 now has a new 4.56 axle ratio to improve launch feel and low-end acceleration. The Dodge Ram SRT-10 rides on 22-inch Viper-style custom wheels. Regular cab models are equipped with 305/40 R22 Pirelli Scorpion tires.

Stopping fast is just as important as going fast, so SRT engineers developed a special braking system for the Ram SRT-10 that utilize heavy-duty Dodge Ram components and unique four-pot opposed-piston calipers that are new for 2005.
