DODGE RAM SRT-10 DETAILS
When the Dodge V-10 was first introduced, there were two very different versions: the race engine, used on the Viper, and the torque, used on the Ram. A V-10 powered Ram 2500 truck was, in truth, similar in feel to a 318-powered 1500, since it was meant for towing more than acceleration.
The newly augmented Viper V-10 is used, intact, on the Ram SRT-10. With 500 horsepower and 525 lb-ft of torque, it is the fastest truck available. Created by the new Performance Vehicle Operations (PVO) team - Chrysler's version of SVO and AMG - the truck used Viper and Prowler engineers along with the teams responsible for NASCAR vehicles and Le Mans Vipers.
SRT-10 is based on the standard SRT name given, confusingly enough, to vehicles modified by the PVO Group - that's Performance Vehicle Operations. SRT originally stood for "Street and Racing Technology" but now stands for "Strip, Road, and Track" - similar to the old R/T designation which seems to have been abandoned.
Only recently off the Saltillo, Mexico, assembly line and not modified in any way for additional power or enhanced aerodynamics, a Dodge Ram SRT-10 posted a two-lap, both-directions average speed of 154.587 mph over a "flying kilometer" on the 4.71-mile oval at the DaimlerChrysler Proving Grounds here in Chelsea. The record run by the Dodge Ram SRT-10 was certified by Guinness World Records and the Sports Car Club of America (SCCA). The previous record was 147.54 mph, set last July by the Ford SVT F-150 Lightning, before the Dodge Ram SRT-10 went into production.
Behind the wheel of the Ram SRT-10 in the record-setting run was Brendan Gaughan, a six-time winner in a Dodge Ram in the 2003 NASCAR Craftsman Truck Series (NCTS). Gaughan makes his NASCAR Nextel Cup debut later this month at the Daytona 500 in the No. 77 Kodak Dodge.
Hein Le Roux, research team member at Guinness World Records, said "People aren't too surprised when they hear about expensive super cars or race cars setting speed records. But few people expect a standard production pickup truck, which they can drive straight off the dealer lot, to be capable of this sort of speed. That's what makes this such a great Guinness World Record." (For more, see our news archives.)
Trevor Creed, Chrysler's Senior Vice President of Design, said: "We spent a lot of time in the wind tunnel with the Ram SRT-10, so that is why you see a deep front fascia with a splitter and a subtle rear wing. In fact, we have managed the aerodynamics of the Ram SRT-10 to give this vehicle performance more befitting a sports car than a truck. The rear wing is not only functional, providing a reduction in lift, but it also provides a reduction in drag, which is a rarity for a wing."
The most noticeable exterior feature of the new 2004 Dodge Ram SRT-10 is a unique hood that features a wide power bulge and scoop sitting atop the signature cross-hair grille. "Viper Powered" badges on either side of the hood scoop leave no doubt as to what resides underneath.
The Dodge Ram SRT-10 is available in black, red and silver only. The Ram SRT-10 rides on unique 22-inch polished aluminum "Viper-style" wheels, the largest wheels available on production pickup. The new front fascia, unique hood with integrated air intake, billet grille, lower ride height and ground-effect moldings make it look "hunkered down."
From the side, effects include an aluminum fuel filler, SRT-10 badging, and visible red brake calipers; from the rear, they include a spoiler and custom fascia with cutout for dual exhausts and a large, center-mounted chrome Ram's head badge.
"There is a slightly understated air about the SRT-10, especially considering its performance potential," said Rick Aneiros, Vice President, Truck Design. "But as powerful as the overall theme of the Ram SRT-10 is, we were determined not to make this another boy racer truck. We added functional aero tweaks to deliver a truck that can handle 150 mph-plus speeds."
Inside, there are heavily bolstered racing-derived leather seats with black suede perforated inserts and a carbon-fiber leather trim steering wheel. Silver trim adorns the center stack and a silver trim strip with an "SRT-10" badge resides on the passenger side air bag. A red Viper start button on the dash goes with the engine, and a custom Hurst shift lever sprouts from a silver metal shift bezel and is topped by a Viper style shift knob. Aluminum performance pedals replace the stock set up.
A new gauge cluster with satin silver-faced gauges feature Viper font and graphics and appropriately recalibrated speedometer and tachometer to accommodate the SRT-10's visceral performance.
Resting on unique engine mounts, the new V-10 engine delivers 90 percent of its whopping 525 lb.-ft. of torque from 1500 to 5600 rpm. The all-new cast aluminum cylinder block has interference-fit cast-iron liners and cross-bolted main caps. Both bore and stroke have been increased over previous Viper models. Block length, block height, bore spacing, firing order, rod length and compression ratio are unchanged.
The Viper V-10 includes a six main bearing crankshaft with increased stroke length and cross-bolted main bearing caps. All-new cast aluminum alloy pistons — weighing slightly less than prior years despite larger diameters — are included, as are all-new cracked-steel connecting rods that are lighter yet stronger.
Cylinder heads on the Viper V-10 are redesigned using semi-permanent mold (SPM) 356 T6 aluminum alloy, 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 also are new for 2003.
A single-piece, central dual-plenum, cast aluminum intake manifold is also new. It boasts shorter runners and a single, non-staged two-barrel throttle body for higher peak horsepower RPM. The intake manifold is an all-inclusive Integrated Air and Fuel Module (IAFM) with tubular fuel rails, injectors, sensors, wiring and throttle body — delivered assembled and pre-tested.
A Ram heavy duty cooling system is modified to handle the needs of the new Viper engine. A custom dual exhaust system is mounted to new exhaust manifolds. The Ram SRT-10 also features a unique oil pan, throttle linkage, transmission mounts, exhaust manifolds, and radiator.
The 2004 Dodge Ram SRT-10 focuses its power through a new Hurst shift linkage and a modified version of the Viper SRT-10's Tremec T56 six-speed manual transmission. The T56 is fully synchronized with electronic reverse lockout. A new 4.5-inch aluminum driveshaft runs to the Viper-sourced transmission and a modified differential with a Dana 80 4.11 rear axle delivers the torque to the road.
The engineers at PVO modified the Ram Heavy Duty's rack-and-pinion steering and independent front suspension. Working with the fully hydroformed Dodge Ram frame, one of the stiffest in the industry, PVO added a custom tuned suspension, dropping the Ram SRT-10 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.
Next came Bilstein shock absorbers, performance-tuned springs, unique aerodynamic aids to enhance the Ram SRT-10's higher speed performance, and 22-inch custom "Viper-style" wheels and 305/40 Pirelli Scorpion tires.
Big brakes, another Dodge Ram staple, are also part of the equation on the 2004 Ram SRT-10. The standard ABS-equipped brakes are fitted with new 15-inch rotors on the front brakes. Rear brakes are modified Ram Heavy Duty 14-inch rotors. Front and rear brakes feature unique red calipers. The new front fascia features brake ducts to provide plenty of cooling for track sessions.
"The Dodge Ram SRT-10 delivers simply phenomenal handling," said Dan Knott, Director-Performance Vehicle Operations (PVO). "But without sacrificing ride quality. This is a truck that you can run to the store in, and then start tackling apexes on your favorite set of twisties. And, depending on your right foot, the V-10 can make the straightaways really short."

The Dodge Ram SRT-10's power is channeled through a Viper six-speed manual transmission that connects to a modified differential and new driveshaft. The Ram SRT-10 will accelerate to sixty mph in an estimated 5.0 seconds and deliver an estimated top speed of 150 mph. More impressively, Ram SRT-10 runs the 0-100-0 mph dash in an estimated 18 seconds.
These figures beat nearly every vehicle made in the US, going back as far as you care to look. As a comparison, the Spirit R/T ran 0-60 in 5.8 seconds, and was the fastest four-door production car in the world during its time. The turbocharged, 220 horsepower Neon SRT-4 runs 0-60 in 5.9 seconds. Most "ordinary" cars run 0-60 in around 9-10 seconds now , down from 12 seconds a decade ago.
Keeping all this power in check is a modified rack and pinion steering and independent front suspension from the 2002 Dodge Ram, which set new handling standards for full-size pickups. Blessed with the stiffest frame in Ram history, the Ram SRT-10 makes the most of its exclusive 24-inch wheels and 305/35 R24 high-performance tires, pulling an estimated 0.92 g's on the skid pad and hitting almost 70 mph on the slalom. A recalibrated, quick-ratio power steering unit enhances steering feel.
The Ram SRT-10's handling is enhanced by the addition of performance-tuned springs and shocks, a rear sway bar and an inch-lower ride height. Bringing the Ram SRT-10 to a halt are four-wheel disc Viper brakes, equipped with standard ABS. Fascia-mounted, faired-in brake ducts aid cooling.
The exterior appearance of the Dodge Ram SRT-10 imparts an almost sinister demeanor with a design that blends the bold, "big-rig" look of the 2002 Dodge Ram with performance styling cues that hint at the extra muscle behind its signature cross-hair grille. It's understated "muscle truck" exterior sends a quiet yet unmistakable message that the Ram SRT-10 owns the fast lane.
Available in black or red only, the crisp lines of the Dodge Ram SRT-10 provide a look of machined elegance with a lower -- and an even bolder -- stance than the standard Ram. The new front fascia, hood with integrated air intake, billet grille, one-inch lower ride height and ground-effect moldings provide plenty of "hunkered down" attitude even before the ignition key is turned. From the side, Ram SRT-10 is distinguished by an aluminum fuel filler, SRT-10 badging and red Viper brake calipers visible behind the 24-inch wheels. A bed-mounted hard tonneau, spoiler and custom rear fascia with cutouts for dual exhausts provide the view for the majority of the motoring public.
Inside, red-piped leather and carbon fiber-look accents complement the performance attitude established by the SRT-10's outward appearance. Silver-faced gauges with Viper font and graphics have an appropriately recalibrated speedometer and tachometer to accommodate the SRT-10's visceral performance. Interior space is maintained from the standard Ram.
Following on the success of the Dodge Ram SRT-10 regular cab pickup, Dodge introduces the Ram SRT-10 Quad Cab, targeted directly at the truck enthusiast who wants SRT performance in a pickup with room for the family and towing capacity.
"We knew when we came out with the world's fastest production pickup that there would be customers who would want that same ultimate performance, but in a pickup that offered four-passenger seating and towing capability," said Dan Knott, Director — Street and Racing Technology (SRT). "So, the question was, 'Can we create a more usable truck for the person who wants to haul more stuff, but is not willing to give up performance?'"
The engine is backed up by a four-speed automatic transmission — a 48RE gearbox, specially adapted from a diesel engine application for its ability to handle monster amounts of torque. A heavy-duty torque converter, custom transmission calibration and two-piece drive shaft were also specifically chosen for overall powertrain integrity and performance. Additionally, the Dodge Ram SRT-10 Quad Cab was fitted with a 4.56 gear ratio to improve launch feel, low-end acceleration and towing capability of up to 7,500 pounds.
SRT engineers began with a fully hydroformed frame as the basis for strength and rigidity. From there, the Ram SRT-10 Quad Cab was fitted with fully-tuned front and rear strut and spring assemblies. Up front, modified steering and independent front suspension carry the load, while in the rear, axle snubbers, performance-tuned springs and Bilstein monotube shocks keep things firmly planted through the corners.
Dodge Ram SRT-10 Quad Cab's braking system was designed by SRT engineers, utilizing heavy-duty Dodge Ram components and unique four-pot opposed-piston calipers that are new for 2005. A three channel anti-lock braking system (ABS) actuates new custom red brake calipers up front that grip 15-inch rotors, and in the rear, modified heavy-duty red calipers grip 14-inch rotors. Front brakes are cooled with air ducted from the front fascia to reduce heat build-up.
Featuring cues reminiscent of Dodge's NASCAR Craftsman Truck Series Ram — such as the deep front fascia equipped with a wind splitter, signature cross-hair grille and sculpted sides — the Dodge Ram SRT-10 Quad Cab features a unique hood with a fully functional air intake that provides added bay cooling. A body-color aluminum tonneau cover, outfitted with a unique spoiler for aerodynamic balance, is standard.
Performance cues inside the Dodge Ram SRT-10 Quad Cab include the Viper-like pushbutton starter, race-inspired, grippy and heavily bolstered seats, a leather-wrapped carbon fiber-patterned steering wheel and brushed metal accents on the instrument panel and door trim panels.
Last summer, Ford SVT established, and therefore set, the Guinness World Record for the world's fastest production pickup truck, with a 148-mph (actually a 147.714405-mph) average over a "flying kilometer." The truck was a 2003 SVT F-150 Lightning.
Dodge's Performance Vehicle Operations (PVO) wasted no time breaking that record. In fact, not waiting for warmer temperatures, a group of Dodge men and women braved a chilly February Michigan afternoon to beat the Ford record and get the Ram SRT-10 in the next edition of the "Guinness Book of World Records."
The Ram SRT-10 is the third Dodge vehicle branded with the Street and Racing Technology label, following the Viper SRT-10 and Neon SRT-4.
For the record, Guinness requires the truck to be "production level," meaning it needs to be identical to what a customer can find for sale at his local dealership. The truck's speed must be measured over a minimum of one kilometer; the record is derived from an average of speeds in both directions within one hour. The run by the SRT-10 Ram, recently off the assembly line at Saltillo, Mexico, was certified by both Guinness World Records and the Sports Car Club of America (SCCA).
PVO's SRT-10 powered right past the Lightning mark by nearly seven
mph, recording a 154.587-mph average in a two-way run over the flying
kilometer. NASCAR Nextel Cup driver Brendan Gaughan raced the big,
non-supercharged V-10 Ram around Chrysler Group's Chelsea Proving
Grounds to get the number. Naturally, the manufacturer's
public-relations team made a huge deal of the record, with an airplane
flying a banner right on cue, reading "Dodge Ram SRT-10, World's
Fastest Pickup Truck" afterwards.
Guinness World Records' research observer Hein Le Roux allowed that the idea of fast pickup trucks is somewhat foreign to British companies like Guinness. But he'd better get used to it: With the next SVT Lightning due out for next year, this could be the beginning of a huge two-way rivalry. But still no Chevy?
If it's power you're after, this truck sets out to deliver it, with 500 horsepower and 525 lb.-ft. of torque. The truck goes from 0 to 60 in approximately five seconds and tops out at about 150 mph.
"There is no replacement for displacement," added Bernhard. "The Ram SRT-10 delivers its astounding performance in a way that only Viper owners will recognize, with an endless rush of torque."
The Viper V-10 includes a six main bearing crankshaft with increased stroke length and cross-bolted main bearing caps. All-new cast aluminum alloy pistons weigh slightly less than prior years. New cracked-steel connecting rods are lighter, but stronger.
