Hi guys, i cant for the life of me figure out if i have 3.55's or 3.92's. I have a 2008 hemi big horn QC with factory 20's and i checked on the cover, checked the inside of my doors and whatnot and couldnt find anything. Is it in the book somewhere?

Any help would be appreciated,

Thanks!

 

It should be on a sticker in the glovebox? Did you check there?


If I remember correctly, which there's a good chance i DONT, I thought someone told me that I could check the diff cover under the truck and it would tell me...My sticker in the glovebox was ripped out-.-

 

theres either gonna be a sticker wrapped around your rear axle with the info, or a sticker in the glove box with that info. if neither of those, you can give your vin to the dealership and request a build sheet. or if you are really desperate, you could jack up the rear of the truck, spin the wheel 1 full rotation, and count how many rotations the drive shaft made.

 

Ya i read that, i couldnt find any sticker in my glove box and no sticker on the differential, its killing me haha.

 

i searched all over, finally found it, thanks guys!

 

Well, what the hell was it, and where did you find it?!?!?! Lol, can't leave us hanging like that

 

Rofl.

Ol' dirty John I like your sense of humor

 

^^^ I dont get it? Thats a legitmate way of checking your ratio, or a good idea anyways......

Lol, maybe I'm the one with no sense of humor.....enlighten me?

 

What was the ratio? Someone told me that trucks with stock 20" from the factory had 3:73 or 3:92 gears.
Jacking up a wheel and counting the driveshaft turns is the old school of checking gear ratio.

 

sorry for leaving you hanging guys! forget i had to get to the resolution haha. It came with 3.92's and it was on the rear axle on the front side of the car (the side opposite the cover.)

The only place i didnt originally look haha.
