My Gear Ratio

[RamBigHorn]

How can I tell which Axel Ratio my Truck has? It does not show it on my sticker.

If it does not tell you, then I would assume it's the lower number which is the base.

You can always look at the tag on the differential. It has the ratio printed on it. You can also get your build sheet which is specific to your truck and lists all components used to build your truck.

Simply plug your Vin number into that link.

Does it launch off the line like a funny car? Then it's a 3.96
OR
Does it bog down when towing a 2,000lb trailer?
Then it's a 3.21.

I kid, I kid

I don't think the electronic locking rear differential is available with the 3.21 gears so I think RamBigHorn must have 3.96. Check build sheet to be sure.

I have the ORP with 3.21. Pretty common.

If you dont see an additional charge for the 3.92 (I think it was $95) you have the 3.21

If you look at the '19 Ram 1500 sales literature, or the online ordering screens, you will see that the 3.21 non-limited slip axle ratio is standard across the line, with the exception of the Rebel. But, I looked at mine and the 3.21 axle is listed in the Standard Equipment column (far left).

Why it wasn't on yours I can't explain. However, I believe if it had the 3.92 axle it would've been listed under Optional Equipment (The 3.55 is standard with the Pentastar V6). By deduction I'm pretty sure you have the 3.21 ratio.

The LSD (Limited Slip Differential) in the 3.21 gears is a $495 Option.

My money says 3.21 given the data available. You can slide under the truck easily enough and see what the attached tag says. Mine is on the driver's side of the rear differential. Had to verify it said 3.92 before purchasing. Not that I don't trust FCA window stickers ... Just a sanity check to ease my own mind.

Register your VIN under the Owners tab on ramtrucks.com and look at the equipment under "Other", if it does not list anything, you have 3.21 (standard). This is from the standard equipment page:
