    Default Gears for '04 Rubicon 5 speed with 35's

    Got an '04 Rubicon, 5 speed and putting on 35's.
    Should I go 4.88 or 5.13 gears?
    I already bought the gears and axles based on another websites advice but haven't had them installed yet...or bought the tires...am going to real soon.
    Not telling what I bought because I want an impartial look.
    What do you all have? Like? Mine's a daily driver with ocasional off road. Weekend driver when I get my beater $500 piece of crap.

    I say 4.88s because you've got a 4:1 t-case.

    Since you've got a manual, 4.88s should return you to the stock power curve. If it was an auto, or you ever planned on going larger than 35" tires you'd want the 5.13s.

    Here's a link that will come in real handy, it allows you to calculate 2 different gear ratios side by side. Makes comparing gears alot easier and eliminates the guess work.

    Just had 4:56's installed in my 06 Rubi last week. I'm on 35's and that brought mine back to factory. Speedo is exactly on again as well.

    If your never going over 35's 488's would work. If you ever plan to put a V-8 in it stay with 488's, Then your good to 37's.

    Since you said it will be a weekend driver when you get you beater, than put the 5.13s in it. Nothing wrong with deep gears, ever.

    4.88's should allow you to run 5th on the open highway with the occasional down shift on steeper hills. 5.13's are great for strictly offroad, but if you ever need to run it on the street you'd hate how low it was for city driving. I know someone mentioned 4.56's in a 2006, but you have to remember the 06 has the 6-speed not the 5 like your's. Stay with the 4.88's!
