As said more info would be good, but 4.10s and 32's was stock on many of the Rubicons.

In 2012 all rubicons with a auto went to 3.73 stock. the new trans at 4.1 on 32s is a bit over geared. BUT it was a option. When i ordered my 12 JKR that was the main option i wanted, none at the time on any lots. all sticks had 4.1.

No need to post in 2 separate threads.

On a 3.6L with an auto, 4.10's on 32's are just fine. RPM's are fine too.

02 WJ Laredo, heavily optioned but stock
12 JK, 3.5" Teraflex/Franken lift, Bilstein 5100's, BFG KM3's 37x12.5/R17
