4.10's is plenty in my book. i am running 34's with 4.10 gears in my cj (dana 44 front & rear).

With a 4.0 I-6, get 4.56s. With the 4 popper, go 4.88s. 4.88 is the deepest you can go with a 30 front axle. If you plan on EVER going to 35s, go as deep as possible now.

The ratio will stay the same if you upgrade to D44s, but you will need to regear the new axles too. D44s can go as deep as 6.38s, but unless you are running 42s, that is WAY overkill.

I would suggest just doing it once when you get the D44s unless you are going to wait a couple years to do the swap, or are not certain you would do the swap.

I have a 06 TJ Sport with auto trans and 33's and it does pretty good but I would like to go to 4.10s or 4.56s. But a local guys that knows Jeeps told me that since I have a Dana 44 rearend and Dana 30 front that I would have to find another carrier for the 44 to go up (numerically) in gears. What do you guys think? oh I currently have 3.73's now.

Do the 4.56s. 4.10s are not enough of a difference from 3.73s to warrant the $$$ to do the swap. If you EVER think you might go to 35s, think long and hard about 4.88s.

Also, might as well do some lockers while you are in there. Save about $500 down the road by not having to tear into the diffs twice, and depending on WHAT lockers you consider, might get a full case locker instead of a new carrier and a lunchbox for the rear. That way, you get a much stronger carrier(Detroit/ARB) for just a little more than a lunchbox locker and stock carrier.

for the ratio, will 4.10 be good enough for just regular old dirt trailers?

and can you point me in the right direction for lockers?

It's impossible to give you the correct ratio recommendation without knowing what engine and transmission your TJ has. Once we have that, then we can provide a sound axle ratio recommendation and then we can talk about lockers.
