Laying Down the Numbers
The SRT-10 is the most powerful production pickup available on the market today. It produces 90 percent of its torque between 1500-5600 rpm and can roar to 60 mph in 4.9 seconds. The quarter mile is gobbled up in 13.3 seconds with a trap speed of 106.9 mph. We found a 3500-rpm launch is required to get the 22-inch rear wheels to spin--anything less than that and the tires would initially break free and then suddenly gain traction and bog the motor. Senior road-test editor Chris Walton was surprised by the truck's ability to hook up during quarter-mile launches. "Who knew a pickup truck with this type of power wouldn't just sit there and roast the rear tires? I was impressed at how well the traction bars [unique to the SRT-10] work to minimize tire spin."
BDespite a 120-horsepower deficit to the SRT-10, the Lighting still managed to whip out respectable test numbers. The blown V-8 is good for a 5.1-second 0-to-60 run and a quarter-mile shot of 13.6 seconds at 102.0 mph. However, testing proved that performance diminishes quickly when the supercharger heats up after just a few runs. Walton says, "Getting a good launch required careful listening to the mechanics of the transmission and supercharger boost. The rest of the run is 'automatic', and I'm just along for the ride."

Both trucks are fitted with oversize disc brakes, helping them stop from 60 within two feet of each other. The SRT-10 came to a stop in 125 feet, while the Ford halted in 123. These are respectable numbers for a passenger car--outstanding for anything with a bed.
Can You Handle This?
Park these trucks side by side, and you notice how much the SRT-10 overshadows the Lightning. The Dodge is 3.5 inches taller than the Ford and almost an inch wider. Being the larger of the two helps convince everyone you're the king of the road, yet some of our staff felt awkward piloting a sport truck so far off the ground.

Helping hustle the SRT-10 around the racetrack is a model-specific, tailored front suspension, including a modified rack-and-pinion, custom front knuckles, shorter, stiffer springs, and special Bilstein shocks. Out back, an anti-roll bar was added to work with the truck's unique elliptical leaf-spring suspension, which incorporates an added leaf that acts as a 1960's style "slapper bar." The setup works amazingly well during hard launches. Ride height has been lowered in the front one inch and three inches in the rear, yet we'd like to see it lowered even more. The big Ram managed a slalom speed of 61.9 mph, slightly beating the Lightning's speed of 61.5 mph.
