I have an 08 1500 Hemi with 3.92's....just ordered 35x12.5x17 inch tires looking to go to a 4.11 or 4.56 and a detroit true lock diff....mild towing and off roading I MOSTLY DO HIGHWAY DRIVING....Im getting mix responses from people on what ratio to go with....any advice??

Thanks,
Ray

 

i plan on getting same tires soon and was thinkin if i was to re-gear i would do the 4.11's cause anywhere i go is 20 miles of highway and interstate. and i think the 456's would be too low for all that high speed crusin

 

Is it really much of a benefit going from 3.92 to 4.11,enough to justify the investment?

 

all I know is with my 35's my rpms at 65 mph have dropped, so I am going to 4:56, I have 3:92 and like you said Jesse too much money for just a little difference

 

i didnt even see that he's got 3.92s DUH!
definitely not worth the bux . i would wait to see what it drives like with the tires on be4 you make a decision.

 

Not worth the cost to go from 3.92s to 4.10s. However, you guys thinking about 4.10s need to realize two things. That the difference in RPMs between 4.10s and 4.56s with 35" tires is only about 250 rpm at 70 mph and that the Hemi has a "sweet spot" when cruising at around 2100-2200 rpms and actually gets better gas mileage than when cruising at say 1800 rpm...
