Hey guys i was just wondering if any of you guys could tell me what gearing i have? I am running about 2000RPM with a auto at 60MPH in overdrive on a set of 31" BFG A/T? I have't had time to look myself and thought about it on my way into work tonight. If ya guys got some info that would help thanks.

 

depends on your setup. engine trans and diffs. there should be a tag on the diffs that says what they are

 

I will have to look? Do you have a auto with 31"s? It just seems like to R's are high for only running 60.

 

If you are running an auto (aw4)trans , stock is 3.55 gears . Mine runs the same approx 2000rpm at 60mph ,I am also running 31's.
Manuals came with 3.07's

 

or if u got a 2.5 in which case u got 4.10s

 

you could go to this web site and do it http://www.novak-adapt.com/knowledge/gearing.htm, you most likely have 4.11 with the AW4 tranny, it can tell you alot about your jeep

 

hey thanks you guys. From that web site that XJ Sport gave me it says i have 4.11's that is probly right since mine has the tow package on it.

 

I dont think they used 4.11's in the 2000's. I know they did back in the day with the v6's and the 4 bangers but i have never seen a newer auto I6 run 4.11's from factory

 

you could always get your build sheet from jeep.com it told me my gear ratio (93 xj)

 

My build sheet told me I drove a minivan

 

you must have done it wrong, did you fill out this form?

You would have 3.55's

 

IF it IS stock with a AW4, then you have 3.55's With 4.11's you would be at a higher RPM than that @ 60mph.

 

Yeah I just did it again last night, hopefully it'll be right this time.
