I'm sure a thread like that had been started but can't find it.
Going to upgrade the rear from a 44 to a 60.
Putting this out for anyone to give recommendations as to anything else I'll need for this job considering I'll be doing it myself.
A low down on my Jeep:
2011 Sahara Unlimited
5.7 Hemi
3.5 AEV lift w/ Billstein [sp] shocks
35" with no additional back spacing
No lockers
Front ARB bumper
Rear LOD w/ swing away
Stock 3.73 gears

Wasn't too sure if re-gearing was necessary because of the hemi (with all things considering, is a power house).
I'd like to start this project beginning-mid fall.

 

What size tires are you running and type of wheeling do you do? Just trying to get an idea behind your motivation to go to a 60?

Also, unless you are running or plan to run a hub conversion in the front, you will be limited to a semi float Currie 60 rear to keep the 5x5 bolt pattern.

 

Teraflex makes a 5X5 OR 5X5.5 Rear 60.

Also you can run adapters to change your bolt patterns.

 

We can do 5x5 or 5.5.5....
Wheel bolt pattern - 5x5” or 5x5½” (8x6.5” available w/Full Float Upgrade)

I stand corrected. I was trying to emphasize the fact that it will be a semi float axle.

 

You bring up a good point though, with a HEMI and (maybe) larger tires down the road, a full float is a good choice.

 

If you have the money go full float right off the bat! I am kicking myself in the ass now because my jeep got fat and now weighs more than I originally planned. I'm bending axle flanges because of this and are now facing buying a new full float rear end and I will have to replace two sets of Spyderlocks beadlock rims because my lug pattern will end up changing. Coming from experience I should have just done 60's full float front and rear(I have ProRock 44 front). Being you have a hemi I would think that would be even more true for you.

I recently saw a forum post from Dynatrac that anything over 5500 pounds should have a full float and not to mention the power of a hemi.

 

Definitely recommend full float!

Some good point. Have Noooo idea what you mean by full float but i'll look it up.
Running 35's now but planning ahead yo 37's.
Not much heavy wheeling just mainly trails and light stuff but only because its my daily driver. But again, planning for the future when I decide to go bigger.

Also since you dont wheel it hard, the rear 44 should be enough for you.
