Drivetrain
The 510HP V10 Viper engine, resting on unique engine mounts, delivers 90 percent of its 525 lb·ft (712 N·m). of torque from 1500 to 5600 rpm. The cast aluminum cylinder block has cast-iron liners and cross-bolted main caps. The bore and stroke have been increased over previous Viper models. The regular cab features a Tremec T56 six-speed manual transmission.

Suspension
PVO engineers modified the Ram Heavy Duty's rack and pinion steering and independent front suspension for use in the Ram SRT. A fully hydroformed frame was used in conjunction with a custom tuned suspension, bringing the Ram SRT-10's ride height one inch lower in the front and two inches lower in the rear. Bilstein shock absorbers (including a 3rd differential torque absorber mounted from the top of the differential to a frame crossmember), performance-tuned springs and unique aerodynamic aids were used to enhance the Ram SRT's higher speed performance.
Wheels
The stock 22 inch rims and Pirelli Scorpion P305/40R22 performance tires gives the SRT-10 the grip that helps it achieve record breaking speed. The standard ABS-equipped brakes are fitted with 15-inch rotors on the front and 14-inch rotors for the back. Two Nascar-inspired brake cooling ducts integrated into the front fascia, provide plenty of cooling for the Ram SRT's brakes.
The total production for the 2004 Dodge Ram SRT-10 was 3,057. For 2005, the total production was 4,027. Due to the short 3 year lifespan of this truck, less than 6,500 Dodge Ram SRT-10s were manufactured. Compared to the 35,000 Ford Lightnings, the Dodge Ram SRT-10 is truly a limited edition truck.
