So Pickuptrucks.com did some testing in 2010 at Milan Dragway in one of their comparisons, and again in 2014 using the same place.
Both times an F250 with the 6.2L V8 gas engine was tested. In the 2010 Shootout, they used a 2011 model, and in 2014, they used a 2014 model. Both were rated at the same 385hp/405tq.
The only difference between the trucks was that one had a 3.73 axle (2014), and the other had a 4.30 axle (2011).
Here are the comparisons:
0-60:
3.73 axle truck - 9.03 sec
4.30 axle truck - 9.80 sec
1/4 mile:
3.73 axle truck - 17.2 sec @ 83.4 mph
4.30 axle truck - 17.5 sec @ 84.3 mph
I would have thought the 4.30 geared truck would have been faster accelerating than the 3.73 truck. Same cab & body style, both 4x4 automatics with the same transmission.
The same thing happened when Pickuptrucks.com tested two GM 1500s, each with the 6.2L V8. The 3.42 truck was slightly slower accelerating than the 3.23 truck. Weird.
Now, for those of you keyboard warriors that are getting ready to type "I didn't buy my truck to drag race" or, "who cares about 0-60 times?"
Save it. It's just a discussion. Take your heart meds and go back to watching the Price is Right. :B

The Dodge Ram beat out the Ford and Chevy in every test and this is what P/U trucks .com wrote:
To some, since Ram had the biggest engine and 4.10:1 axle gears (where the Ford was only equipped with 3.73:1 axle gears), the outcome was not unexpected. But it's worth noting here the Ford did outweigh the other trucks by at least 120 pounds (more than the Ram and 380 pounds more than the Chevy), yet it gave our driver the most thrilling launches off the line. Clearly, the Ford engineers have done the best job of allowing the most power to get to the rear wheels for hard acceleration starts. Of course, that also meant we'd have to be careful at stop-sign launches in the rain.
During our loaded runs, which included 62 bags of rock salt (weighing 40 pounds each) moved from one bed to another by a team of Cars.com editors, we had, as you might expect, no trouble with spinning tires at the start line. Again, the bigger and stronger Ram 2500 muscled ahead of the other two competitors.The above should be enough to answer your question. Transmission differences and weight differences. You must count the transmission ratio with the rear axle ratio to arrive at the FINAL DRIVE ratio. Only comparing the rear ends is meaningless.
