Axle ratio and acceleration question
I am about to buy a Ram 1500 Bighorn 5.7L Hemi crew cab 4x4 for my daily driving vehicle and to pull a 7,500 lb camper about 6-8 times per year. The 3.55 ratio can pull 7,450 and the 3.92 ratio can pull 8,500 lbs. I prefer to have some reserve and would like to get the 3.92 ratio. The sales rep said I would lose some of the "ride" that I enjoy and the ability to accelerate off the block. I love the Hemi's ability to go 0-60 and I don't want to lose that. I am trying to educate myself on axle ratios and will go for the higher one if someone tells me they have great "off the block" acceleration. The Dodge site states
"A "high" ratio, one with a high number of drive shaft turns like the 4.1:1 example above, is better for quick acceleration, climbing grades, carrying loads or pulling a trailer. However, it results in lower fuel economy and is noisier when running at high vehicle speeds."
Keep in mind I do NOT care about fuel economy. Some sites say the worse gas mileage is undetectable to the user. I want to be able to pull adequately . Is the increase in acceleration in the 3.92 only in the higher RPM ranges and gears? Does it decrease performance in the lower gears "off the block?"
thanks for any help you can provide this long time aspiring Dodge Ram owner!
