How do I find out what gear ratio im running?? 2008 1500 QC Hemi 20" wheels

 

check your build sheet.

they should have gears in it

 

Do you have factory tow package??? then 3:92's. If not maybe 3:55's. There should be a tag on the diff cover that will tell you.

 

check in the glove box, there is a sticker on the bottom that says what you have

 

NEVER ASSUME you have 3.92s with factory tow. The gears are a separate order item and the idiots doing the ordering often leave the standard 3.55s.
Check the sticker in the glove box, look at the rear axle for a tag, or order a build sheet from Dodge to be sure...

 

so I just call dodge and give them my vin # and ask for a build sheet??

 

there may be a sticker on your Axel also...
or send an email to: customerassist@chrysler.com with your vin# and they will email you a build sheet. At least they used to..

 

+1^, thats the fastest way. but u should get a build sheet anyways from the link above, they are free and have alot of good info on it.

 

yeah, just email them and they should send you one really quickly. i got mine in a couple days

 

i dunno how quick it will be this time of year with everything that's going on and all?????

I thought I read somewhere that ALL 1500's with 20's and the Factory Tow package came with 3:92's.
But not all 1500's that have 20's have 3:92's but rather 3:55 unless ordered with the 3:92's?????
