Gears: What do I have, upgrade?
I have an 03 SLT Standard Cab (4WD). How can I figure out what gears I have and would it be worth the money to upgrade? Looking for more power. Thanks.

There should be a sticker on the axle itself that tells you your gearing. Look under the back toward the driverside I think is where they put it on that year model.

If you have the owners manual there should be a section that tells you where to find the build codes so you can check. On my 2002 the info was on a sticker in the glove box.

You should also be able to email chrysler and request your build sheet that will have every option about your truck listed on it (including gear ratio).

My build sheet says

DJMS 205MM HD Front Axle
DMDS 3.55 Rear Axle Ratio
DRBS Corporate 9.25 LD Rear Axle

Don't know why I didn't look there before. Now can someone decipher for me please?

I can't comment on the front axle, but the rest means you have 3.55 gearing (pretty typical) and it is the 9.25" axle (standard on all ram 1500 models; this is just basically a name, you can just ignore the 9.25" is basically just an identifier). If you don't have anything (probably just under those items) that says "anti spin differential" or something similar to this then you have an "open" differential, which means both wheels won't provide torque to the ground, only one wheel will. Common "lay mans term" for when both wheels provide torque to the ground is posi traction...

Ok, I am thinking of upping to 4.56 gears. I have been reading alot on that lately.

snrusnak 01-12-2012 11:58 PM

Yeah many 4.7L guys do that. I think 4.10's is tall enough, I'm afraid of losing hwy mpg though. Also, on the drag strip (depending on gear ratio and tire size) higher numerical gearing is not always better...

I dont know alot about gearing. I dont want to drag, but more power would be better. Why does it seem like every 4.7 guy goes to 4.56 gears?

BCWhite 01-13-2012 12:51 AM

From what I see, 4.56s are for pulling power and drag racing. My education continues because I am liking what I am reading about acceleration with 4.10s.
