    2. My Smitty has worked well for me, but it is really up to you and your budget.

    3. I think you would be good with 4.88s but if you are really thinking 37's then you definitely want 5.13s. However, that opens up a whole nother can o worms (theoretically speaking).

    4. I will recommend my Rancho rear as it was only $400 but if you are bad ass enough to build your own then more power to ya

    if you want to go to 37's are you going to keep that front 30 or swap in something beefy. if you want to lock the front you have already pushed the limits of a d30 without throwing a bunch of money at it then it is still a d30.....

    I don't think JK 30s are the same thing as a CJ 30.

    they have the larger 297 u joint and d30 ring and pinion. similar strength axles iirc. The outers are the same as the jk d44 bj's out. an upgrade from cj series but not strong enough for 37's and he will prob want a locker
    a rubi d44 would hold up with a tube sleeve and inner c braces

    well they have 33 and 35 spline dana 44 shafts from the factory these days and I didn't think 297s were used anymore.

    If and when I decided to go to 37's id be swapping in something different. Thats why itll be down the road, but Im thinking I can always add things to prepare for that point if it ever happens. I know im pushing the d30 as it is, but Im probably going to leave it open and wheel what I can without pushing it too far. I have the c gussets which seem to be the main point the 35's **** up on these 30's.

    Been lookin at the Tom Woods pretty hard. There design looks pretty solid. It runs $450 for a 1310. http://www.4xshaft.com/JK-jeep.html
    JEReel runs $460. http://reeldriveline.com/catalog/fro...trans-p-1.html
    Teraflex runs $580.
    Coastline 1310 runs $475.

    Any opinions on these or any other choices? 1310 strong enough or should I be lookin at 1350's?
    Guess I would need to go ahead and do the front lower adj control arms while Im at it.

    1310 is plenty strong. I ran them with 40s and twisted the slip part of the driveshaft off, and broke a few d60 rear shafts, and a couple front ones, and only once did I break a 1310 joint. I still think leaf springs are the main reason people break driveshaft joints.

    My little sister has one of these in a rubicon on 35s. I think those have 4.10 gears from the factory. If so it is not close to enough. Running with OD off seems OK. I figure that's the equivalent to about 5.5 gears in OD. So 5.13 gears would definitely not be too low. That little motor got no guts.

    Thanks, winch seems decent but haven't had to use it so we will see.

    At this point id kill for 4.10s.... 3.21s with 35s is wearin on me, settin aside the funds for 5.13s hopefully this semester
