Eaton Truloc Differentials

Anyone install Eaton Trutrac differentials in a 2013 or 2014 JK? Eaton's application chart only goes up to 2012. Upon some research, I'm being told that's it's not recommended to install a LSD in one of these newer JK's, which doesn't make sense since you can order one for the rear from the factory. Supposedly some installs are experiencing issues with LSD's conflicting with the working of the BLD. I was told it's ok to install a air or e-lockers as in the Rubicon's. Anyone with any experience with this would be great.

The Eaton Truetrac LSD is not the same as the stock Trac-loc LSD. Totally different differential. The Eaton Truetrac has superior traction performance compared to the stock LSD and it can be used in the front or rear axle with no problems. It is a gear driven unit where the stock LSD is clutch based. The Eaton Truetrac is easily the best LSD available for the JKs.

Thanks for the feedback guys, glad to hear that some newer Wranglers are not having an issue. I actually had 2 retailers deter me from purchasing front and rear Truetracs for my Jeep. I'm a little confused as what to do right now. I'd really like to find out what happened to the individuals who had problems before I spend all that $$$ on gears and differentials.

2012 here but figured I'd weigh in.

I dropped a trutrac in the rear when I regeared. Love it. Very helpful on and off road.

Hey, appreciate the compliment. It's a slow work in progress.

The Detroit truetrac I put in my 2013 jku front d30 is a eaton product . Just google ( Detroit truetrac ) tells you all about them. I have heard when installed in rear diff ,bolt holes for ring gear have to be enlarged ?. Good luck !

I believe the 2009 and earlier Truetracs did need to have the holes enlarged for some gear ratios, no longer an issue. Eaton re-designed them and beefed up the case at the same time. Now rated to 37" tires.

Ran TrueTracs front and rear in my 07 JK for many years with zero problems. Suprisingly good hookup for an LSD. Locker traction with no lurching and popping in turns.

You can drag the brake a little to trick them into locking up if your not getting full posi.

Bought them from Summit Racing, just ask for a discount.
Eaton reccomend Timkin bearing and shim kit for the install. No special modified friction gear oil need like the TracLoc, standard 90 wt is fine with the TrueTracs.

I am running TrueTracs front and rear in my 13 and they are fantastic.

No noise and easy/smooth lockup.

They have been in there for a year now.

Thanks for reply. Glad to hear your are also not having any problems. Today I found a performance axle and suspension shop about 80 miles from my home. I called them and asked them the same questions. They don't believe that there should be any any issue. They're looking into it and am going to call me back next week.

I also noticed in your signature that you installed 4.56s with 35" tires. Are you happy with the performance, drivability and mpg? Did you sleeve or truss your front axle? I'm still trying to decide on 4.11s or 4.56s.

Did they give you a quote? A good shop by me quoted $325 to install the front and its about $430 online. I currently have the factory LSD rear but would like to eventually do the rear too.

I really like the performance of the 4.56's on and off road.

I compute about 22 miles each way and it is all in town speeds.

I avoid the Interstate if at all possible.

It will do the Interstate but I like to see other things besides bill boards.

Gas mileage..... Don't know. I can't keep my foot out of it.

Didn't sleeve or gusset as I don't do rocks and there isn't any need for full on throttle with these gears.

Crawls very nicely you know.

BTW, with traction control off, it will turn both tires from a dead stop.

So tire wear isn't a concern either..

My 2013 JKU has the factory LSD and it is great for daily driving.
My 09 Rubicon unlimited sucks for daily driving without any kind of LSD.
4wd hi just to get going on wet pavement in the Rubi. I have been considering the Eaton Truetrac, but not sure I want to tackle the install myself. My history with paying for work to be done usually ends with me being disappointed. So I am not real eager to go that direction either.

Still haven't heard from them. I sent them a lengthy email today with the questions to. I'll give them another day or two before I try calling them. We've been getting hit hard here in the North East with snow, and we're getting more tonight. I'll post the quotes as soon as I get them.

Thanks for the reply! If you have the info, could you post the Eaton part numbers for the front and rear differentials you installed and where you purchased them from. This would be good info for myself and others interested in this setup or at least good information to take to our installers for their research. Thanks!

Got the quote today.

Dana30 axle sleeved and gussets welded : $577.26
Dana30 4.56's and Eaton Trutrac installed : $684.16
Dana44 4.56's and Grizzly Locker installed : $684.16

The above is just labor charges. I'm going to contact them tomorrow since they quoted me for a Grizzly locker for the rear instead of a Trutrac

They're prices for the ring and pinion sets and front and rear diff's are comparable to what I can get them on line for. I think they're install prices are a little high.

Best prices I found for the truetracs online after shipping was at www.drivetrainamerica.com

I am not sure how much more is involved installing new gears when adding a truetrac but i wouldn't think that much. Why would you do auto locker in the rear vs truetrac? Do you play in the rocks or get wheels in the air.

Btw where are you located?

Installing just differentials would be a little quicker and therefore a little less expensive to install. There is no need to remove the pinion gear.
The place I got the quote from quoted for 8 hr for each axel for installing the ring and pinion and differential. Another place told me it would take about 4 to 5 hours just to do a differential swap. That works out to about a $240 savings per axle if I just swap out the diff's. I just figure that if I'm going to have some one open it up I might as well get the entire job done. It's better that paying for it again a year or two from now. I live in NEPA, near Scranton.

If you don't mind driving the shop that quoted me is called globex performance in toms river NJ. You can always visit the shore and get some fist pumping in.

Thanks, I may just give them a call.

On another note, I just did some more research. I think they quoted me for a Grizzly locker for the rear, because from what someone mentioned above and from what I just read, you have to drill out the ring holes on a Eaton Trutrac to 1/2" in order to accept the new ring gear. I'll try to find out for sure tomorrow. I know I don't want to drill out a new differential. Not sure which way I'm going to go now

Give them a call they asked me if I wanted to do gears and sleeves and gussets at the same time since its all apart and would save on labor. As far as drilling out I thought they changed the design as the older one was only good up to 3.73 gears then needed to be drilled, but the new chart is not gear specific like the front one is.

You won't have to drill out the Truetrac carrier if you're using aftermarket gear sets...only if you're using the stock gears. Most of the aftermarket gear sets and the Truetrac are drilled for 3/8" and 7/16" bolts. The 7/16" bolts that come with the install kits work just fine. Summit Racing sometimes has the Truetracs on special.

that's kinda Funny because I have 3.73 and wasn't going to regear. I wonder what size holes are in stock 4.10s

1/2" which would require drilling the Truetrac.

I called Eaton today just to get some information from the manufacturer and 14JKU is correct If I keep my stock gears I need to drill out the holes to fit the bolts, but If I regear like you are MarksJKU then it will bolt right up. The Max tire size I plan to run is 34s I don't think there is really any reason to regear. I might just stick with my original plan to do the front since I have the factory LSD.

Not to dispute what you say but I was under the impression that the trac-locs were also a gear driven LSD, is this incorrect.
