The Dodge Ram SRT-10 is a sport pickup truck produced by Dodge, based on the standard Ram 1500, with only 10,046 units built. It was introduced as a concept at the January 2002 North American International Auto Show, while the production model was introduced in 2003 as a 2004 model year.

Development

The Dodge Ram SRT was created by DaimlerChrysler's PVO (Performance Vehicle Operations) division, using Dodge Viper and Plymouth Prowler engineers. Extensive wind tunnel testing was used in styling the exterior of the Ram SRT-10. This is the second time that Dodge has put a Viper engine into a Ram pickup. At the 1996 Chicago Auto Show, Dodge introduced a concept Dodge Ram with a Viper Generation 2 engine, but it was not put into production. The Dodge Ram VTS was painted Banzai Blue with dual white skunk stripes, housed an 8.0 L (488 cid) V10, a six-speed Borg-Warner manual gearbox, and 17 in (432 mm) Viper GTS wheels wrapped in BF Goodrich 275/60-HR17 Comp T/A HR4 tires.

Overview

Dodge Ram SRT-10 engine (with aftermarket intake tube)

The SRT-10 featured a Chrysler 8.3 liter V10 that was first used in the third generation Viper. This engine produced 500 bhp (373 kW; 507 PS) at 5,600 rpm and 525 lb⋅ft (712 N⋅m) of torque at 4,200 rpm. The regular cab, with a total curb weight of 5,130 lb (2,327 kg), reached a top speed of 154 mph (248 km/h), and could accelerate from 0 to 60 mph (97 km/h) in 4.9 seconds, whereas the Quad Cab, weighing 5,618 lb (2,548 kg), achieved 0-60 mph (97 km/h) in 5.3 seconds and reached a top speed of 147 mph (237 km/h). The regular cab could complete the ¹⁄₄ mi (400 m) in 13.6 seconds at 106 mph (171 km/h), the Quad Cab in 13.7 seconds at 100 mph (161 km/h). The engine produced one horsepower for every 10.3 lbs of vehicle weight in the regular cab. The regular cab generated .86 g of grip on a 300 ft (91 m) skidpad, while the Quad Cab generated .83 g. The regular cab was rated by the EPA at 9 MPG city/15 highway, while the Quad Cab was rated at 9 city/12 MPG highway.

Drivetrain

The V10 Viper engine delivered 90 percent of its torque from 1500 to 5600 rpm. The cast aluminum cylinder block had cast-iron liners and cross-bolted main caps. The bore and stroke had been increased over previous Viper models. Compression ratio, firing order, rod length, block height and block length were unchanged from the second-generation Viper engine. The regular cab featured a Tremec T-56 transmission, while the Quad Cab utilized a 48RE four-speed automatic transmission modified from the Ram Heavy Duty transmission. Both regular cab and Quad Cab used a Dana 60 rear axle.

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 6 ft 3 in (1.91 m), giving the regular cab an overall length of 17 ft 7 in (5.36 m), and 19 ft 2 in (5.84 m) 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 U-Connect for hands free communication through your car stereo as a factory option also full digital Satellite radio. The doors on both the Standard cab and Quad had silver accents along the middle above the arm rest. It also came with a leather trimmed steering wheel and with heavily bolstered racing-derived suede-trimmed charcoal leather seats. The center stack was adorned with silver trim, and a silver trim strip with the SRT-10 logo resided under the passenger-side air bag cover. Taking a cue from the Dodge Viper, the Ram SRT-10 came with a red start button on the dash. The manual transmission regular cab featured a Hurst shift lever, which sprouted from a silver metal shift bezel and was fitted with a Viper shift knob. Aluminum performance-inspired pedals replaced the stock setup. The gauge cluster featured satin silver-faced gauges and Viper font and graphics. The A-Pillar on Driver's side has an Oil Temperature Gauge, sporting the SRT logo. The speedometer and tachometer were re-calibrated to match the Ram SRT-10's increased performance. Optional sunroof was electric, as was a small electric rear window.

Colors

Excluding the special editions, the 2004–2005 Ram SRT-10 came in three colors: Black Clear Coat, Bright Silver Metallic Clear Coat, and Flame Red Clear Coat. The redesigned 2006 Ram SRT-10 came in Mineral Gray Metallic, Inferno Red Crystal Pearl Coat, Brilliant Black Crystal Clear Coat, Flame Red Clear Coat and Black Clear Coat.

Wheels and brakes

The stock 22 in (559 mm) wheels were fitted with Pirelli Scorpion P305/40R-22 performance tires and modeled after the 10-spoke wheels available on the Viper. The brakes for the 2004 model (front and rear) and 2005-06 (rear) were modified from the Ram Heavy Duty truck for use in the Ram SRT-10. The standard ABS-equipped brakes were fitted with 15 in (381 mm) rotors in front and 14 in (356 mm) rotors out back. 2004 models used red-painted two-piston sliding brake calipers front and rear; these were replaced with larger four-piston monoblock calipers up front in 2005–06, designed by TRW and unique to the SRT-10. Two NASCAR-inspired brake cooling ducts integrated into the front fascia provide cooling for the Ram SRT-10's brakes.

Quad cab

Dodge RAM SRT-10 Quad Cab

Following the success of the Ram SRT-10 regular cab, Dodge decided to introduce a Quad Cab version starting in the 2005 model year. The new Quad Cab was aimed at enthusiasts who wanted a performance truck, but did not want a single cab. The Quad Cab was fitted with a 4.56 final-drive gear ratio to improve low-end acceleration and was rated at 7,500 lb (3,402 kg) towing capacity. A body-color aluminum tonneau cover with an aerodynamic spoiler came standard on the Quad Cab. The Quad Cab was only offered with a 4-speed automatic transmission (the 48RE borrowed from the Heavy Duty with the Cummins ISB turbo-diesel). The 48RE was rated to handle up to 700 lb⋅ft (949 N⋅m) of torque.
