Dodge chose the 2003 Chicago Auto Show as the place to showcase their all-new performance pickup truck, the Viper-powered 2004 Dodge Ram SRT-10. This vehicle showcased what at the time was the highest displacement engine available in a factory pickup—the same 8.3-liter V10 engine that powered the 2003 Dodge Viper

Power Monster

Produced from 2004 to 2006, the Dodge Ram SRT-10 with the Viper engine was the fastest, most powerful pickup truck you could buy. It delivered 500 horsepower and 525 lb.-ft. of torque, clocked a 0-to-60 time of approximately five seconds, and topped out at a record-setting 150 mph.

Wolfgang Bernhard, Chief Operating Officer for the Chrysler Group, told reporters:

"The Dodge Ram SRT-10 may be the first halo truck, but trust me, this truck is no angel...[it] is true to the performance ideals that created the original Dodge Viper: keep it simple and make it fast. There is no replacement for displacement. The Ram SRT-10 delivers its astounding performance in a way that only Viper owners will recognize, with an endless rush of torque."

Available colors were black, red, and silver, and the truck featured unique 22-inch wheels. It was introduced as a two-seater, but Dodge introduced a quad-cab model in 2005. 

Revamped Engine

The all-new V-10 engine delivered 90 percent of its 525 lb-ft of torque from 1500 to 5600 rpm. The cast-aluminum cylinder block featured interference-fit cast-iron liners and cross-bolted main caps. Both bore and stroke had been increased over previous Viper models. Block length, block height, bore spacing, firing order, rod length, and compression ratio remained the same.

The Viper V-10 included a six main bearing crankshaft with increased stroke length and cross-bolted main bearing caps. All-new cast aluminum alloy pistons weighed slightly less than prior years, and the new cracked-steel connecting rods were lighter but stronger.

Additional engine features included:

  • Redesigned semi-permanent mold (SPM) 356 T6 aluminum cylinder heads, with improved intake port, exhaust port, and combustion chamber cooling.
  • Lower-profile die-cast magnesium cylinder head covers with steel internal baffles and anti-slosh foam.
  • A single-piece, central dual-plenum, cast aluminum intake manifold.
  • Shorter runners and a single, non-staged two-barrel throttle body, which provided higher peak horsepower RPM.
  • An integrated air and fuel module (IAFM) intake manifold with tubular fuel rails, injectors, sensors, wiring, and throttle body, which was delivered assembled and pre-tested.
  • A Ram Heavy Duty cooling system modified to handle the needs of the new Viper engine. A custom dual exhaust system was mounted to new exhaust manifolds.

All-New Power Train

The Ram featured a new Hurst shift linkage and a modified version of the Viper SRT-10's Tremec T56 six-speed manual transmission. The T56 was fully synchronized, with an electronic reverse lockout.

A new driveshaft ran to the Viper-sourced transmission, and a modified differential with a 4.10 rear axle delivered the torque to the road. The SRT-10 featured a fully hydroformed Dodge Ram frame, one of the stiffest in the industry, and a suspension that had been dropped one inch at the front and two inches at the rear.

New front and rear strut assemblies and a rear sway bar were added to handle the increased cornering loads.

Bilstein shock absorbers, performance-tuned springs, 22-inch custom "Viper-style" wheels, and 305/40 Pirelli Scorpion Tires helped keep the ride smooth and stable.

Standard ABS-equipped brakes were fitted with new 15-inch rotors on the front, while the rear brakes featured modified Ram Heavy Duty 14-inch rotors. Both were outfitted with unique red calipers. The Ram's new front fascia also include brake ducts to provide plenty of cooling for track sessions.
