3.55 or 3.92

[Safety1]

How do I know with out taking things apart how do I know if the axle is the 3.92 like dealer said when I bought the truck? It is a 2012 Laramie 1500.

Crawl under truck and look at tag on rear axle also.

Can I be a novice for a moment and ask. My truck has 3.55 based on the specs, what does that actually mean, in terms of what it's ratio-Ing and also for towing type stuff, people talk a lot about the ratio, does that give me more power than something less than 3.55 and less power than something higher? Sorry not trying to thred jack

Thanks guys all the info was good, and I don't see anything wrong with the question Coffeeholic but I cannot truly answer that for you unless the root meaning is that the 3.92 can handle more torque

Bigger gears will give you more low end torque = better for towing and getting the load rolling easier, also good for rotating larger tires without bogging down your truck

Thanks for the link,..I was wondering the same thing.

Separate question,....when I look up my vin it says "Raised ride height"
Do they make different height springs?

Specifically, for every 3.55 rotations of the driveshaft, the wheels turn once. Or, on the 3.92s, 3.92 times.

Higher number means easier to turn the driveshaft and put power to the wheels, but because it takes more driveshaft rotations to turn the wheels, it means for any given road speed your engine is turning higher RPMs.

Bigger number is generally better for towing, because the engine has a bigger mechanical advantage. Lower number is better for quiet cruising and fuel economy.

Does that help?
