I have a 2013 JKU auto and am considering re-gearing when I get my tires (315/70R17 nitto trail grapplers). My rig came with the factory limited slip differential. I was wondering if you would do anything in regards to limited slip / locker when doing the re-gear. I don't think I want to go the route of air lockers as I don't see myself needing that kind of set up and costs for my uses.

My rig is my daily driver and doesn't get a bunch of time off-road (blasphemy I know LOL). Would you just leave the factory limited slip in or would you look at another option? If you suggest something else, please let me know specifics i.e. manu. and product. Thanks.

 

Your limited slip will work OK until you have a wheel leave the ground and then the wheel in the air will just spin. The E- Lockers work really well and won't interfere with the wheel sensors TC & ABS. The install isn't bad either.

 

With the amount of wheeling it sounds like you do, stay with the l.s. ls stops 1 tire from spinning even with 1 tire in the air.except under extreme traction differences like full throttle.

 

If you don't wheel a lot, the LSD will be fine. If you find yourself with a wheel in the air once in a while, the BLD (Brake Lock Differential) will handle 90% of cases.

You might want to consider a Detroit Truetrac while they are in there doing the gear work.

It is a gear driven Limited Slip device...there are no friction disks to wear out.


Detroit Truetrac® Differential

 

As noted above, if you lift tires offroad, expect the clutches in your factory limited to wear out, making it an open diff. The Truetrac is gear driven, (no clutches), so it may be a great replacement option. You can find the front d30 for $390, and the rear d44 for $460. Sure beats paying two grand for a pair of selectables for those who don't need them.


This is a decent over-view of lockers for those who haven't read it. (though it has not been updated for the new 4 pin E-locker, or the possible auto-locker issues for 2012+ JK's.)

TrueTracs are the way to go if you don't rock crawl most of the time.
Great in sand and mud.
I installed in the rear when I did my gears, will probably do front if I ever go for a 44 up front.

 

I ran the Detroit Eaton TrueTrac LSD in the front of my 07 2 door and used the factory rear LSD for years and never had any problems at all. Even on 35" MT's.

If you get into a situation where 1 rear wheel is spinning drag the e-brake a little and it will trick the factory LSD into locking up.

With the D30 front axle I was worried about snapping u-joints or axle shafts with a full case locker, the LSD seemed to be a safer choice.

The TrueTrac handles great in snow, doesn't jerk on sharp turns and you don't have to do anything to engage it. You won't even know it's there.

 

When I regeared my 12' JKU I went with an ARB in the rear and the TRU Trac up front in the D30. I am very happy with the Tru Trac up front and like mentioned it handled great in the snow this past winter.

 

I wanted to bring this thread back up since I now have my rig kind of set up in regards to tires, armor, etc. Just to re-cap... I have a 2013 JKU auto and am considering locker/limited slip options for when I re-gear. I was wondering what you would go with considering my information. i.e. leave factory rear LSD in, change out rear LSD to a trutrac, change our rear to locker....and for the front - selectable locker (electric or air), trutrac, etc. etc.?

My rig and info:
- 2013 Jeep Wrangler Unlimited D30 front axle with 3:73 gears and factory limited slip differential in rear D44. May change to 4:56 gears and possibly change out front D30 to PR44.
- 2.5 Rock Krawler Max Travel Kit
- Currently running Goodear Duratrac 315/70R17. May go to Nitto Trail Grapplers 35x12.50 in the future (heavier tire).

- My rig is my daily drive and see a lot of and mostly pavement time. Mostly day to day in town driving and a few road trips from time to time. However, I would like to get it where it's good for that but can handle some decent off-roading as well. Terrain around here is mostly rolling hills, muddy trails with ruts, however, we do have an off-road park about 2hrs away that offers some rocks.

So, given my rig, driving, and terrain information. What would you do in regards to lockers/LSD when I re-gear? Front - nothing, trutrac, E-locker, air locker...Rear - factory lsd, trutrac, e-locker, air locker, other. Please let me know your thoughts, opinions, and please be specific on what you recommend and why. Thanks and I really appreciate you help, opnions and recommendations.
