In my opinion, an 8.8 is the best, unless you are deciding to go full width. If you can't find an 8.8, a D44 is a good second choice.

Re: best rearend

A Detroit locker doesn't "Lock Up" whenever it wants. It is always locked up when under power.


Some other questions need to be addressed. What size tire are you currently running and do you plan on going bigger?

That's my vote too. If you're going big, especially, you'll want the full width and the rock-solid nature of the 14 bolt.

The 8.8 is good if you're sticking to 35" or smaller tires.

ford 8.8 dana 44 or ford 9" all would be good picks based on your 33's or if you move up to 35s your fine as well..

I would not run 38's on a 14B. The 14B has a monster diff and you will be dragging it on everything. You could certainly shave it but 40's are the smallest tire I would run even on a shaved 14B.

As for finding one well I would start at your local junkyard or CL. Could always buy a donor truck.

You are better off searching for tech like this on Pirate.

Its an option.. but its a big axle.. hence even with 38's its going to be low to the ground. front and rear 60's would give a bit more clearance and can handle that size tire. some say ford 10.25(think that's the one) would also work. I ran 60's front and rear on a past TJ.

The Original Poster is only planning on 33's so smaller axles would be better.

Its an auto so they are a little easier on axles (less jerking and hard hits)

I can't really think of what's axles would be best but Dana 60's or a 14 bolt would be massive overkill. Even in a full size truck only running 33's.

On a side note.

Lockers. Everyone talks about locking and unlocking with "auto" lockers. This is how most auto lockers work.

No axle shaft can ever spin slower than the ring gear. Only faster.

So as you lay out of the throttle it may feel as though your on locked.

If you want a locker that always stays locked when you want it too you need a selectible locker.

ARB or OX. If there are other brands I don't know about them.

You might check what parts are avalible for the axles you want before buying anything.

Also. What side your t-case drops on will limit what axles you choose
