May be a stupid question, but oh well...
 
Running a 2dr Sport with 3.21 gears. About to add wheels/tires (35") and a lift kit. I plan to regear in the very near future to 4.56 (maybe 4.88). That said, once the diff's are open, should I even consider dropping lockers in there provided my wallet can stand them? Also, that said, if so, what should I be looking at dropping in there? This won't be any rock crawler as I live in MS and there aren't many "rocks" here, but definitely will see the mud and trails.

thanks for any advice!

this ought to be interesting.. i've spoken to a couple guys and the majority seem to agree with lockers up front and leaving the LSD in the rear...

i'm sort of in your shoes. 3.73 auto, already running 35s, but getting to the point where gears and axles are coming soon..

In for replies myself. I have 3.21 and just put my 3" lift on. My wheels and tires will be in tomorrow. I think I'll do 4.56 myself, but guess while things are open lockers can't hurt (cept my wallet..lol)

Your avatar is a 4dr:confused:

Aynway are you a 2012 or prior model JK? If prior to 2012 I would suggest 5.13's. 4.56 are a waste and IMO 4.88's are a little under geared for 35's. If you are a 2012 then 4.88's would be good, even 4.56's on a manual trans.

Anyway if you are not seeing any rocks in your off road adventures then I would say save the money on the lockers. Maybe get Detroit Truetracs F/R or Selectable front and Truetrac rear.

Once you get all the stuff put on take it wheeling and see how it does. Maybe for you lockers are not needed. As a lot of jeepers say stock jeeps are very capable offroad. Dont forget you have the BLD which helps out a lot to. Did you have chance to read the insidelines jeep wrangler blog.

Daniel...

1st off, the avatar is the wife's 2011 Mall Crawler. In May, I purchased my 2012 (it's an auto...should have specified). However, I live/work in Iraq, so I haven't gotten any pics to update my avatar. Will do so when I go home for a couple weeks in Sep and put the tires/wheels/lift on...

Probably won't do the regear in Sep as I'll only be home a couple weeks, and I can live with the "underpowered" rig until I get home in Dec, giving me time to save some extra money's to put towards it.

Forgive the ignorance here, but what is BLD?

Kevin, the 35s on your 2012 with 3.21s should be tolerable. I have 3.73 on my auto 08 with 35s and I tolerate it. I am, however, going to install 5.13 soon. I would consider a 2012 3.21 w/ 35s like my 3.73 2008 w/ 35s. As to what to consider your re gear to, I would say 4.88 since you are an automatic.

It is smart to install lockers the same time you are paying re gear labor but for F/R selectable, youll be spending about another $1K or 2 depending on the brand. You can go with auto lockers, lunchboxes or LSDs for cheaper than selectable but you have to weigh the pros and cons of the auto lockers on a DD rig.

Personally I am going with Detroit Truetrac (LSD) rear and Eaton E Locker up front (selectable). Most reviews say that JKs BLD and the Truetrac are a match made in heaven. Plus I like to do snow a lot too, so all around lockers wont do it for me, nor will auto lockers. I think the Truetrac will get me up and over almost everything, especially in 4WD and I will have the option of locking my front up if I need more traction.

Dan, don't you think that's a little tall for a DD also? :confused: I'm in Florida in a 2DR JK... and I've been thinking that 4.88 is sort of as big a gear as I should go.

install 513's and add front and rear arb air lockers if you got the money.

that will put you around $4K for parts and labor.

you just shouldknow the limits with the dana30 in the front end and the limitations you will need to put in place if you get a new r&P and a combination of lockers installed.

the second you get wheel spin with 513's and your arb air lockers actuated in your front end and the moment you get traction at a higher RPM the sooner you will hear that bang sound.

I just put 5.13 in when I put on rcv shafts and arb lockers front and back. I used them in mammoth and I couldn't be happier. I am running 37 mtr's.

you really think that tall of a gear with 35s in florida in an auto? i mean some day i'd like to retire in the rockies... but that could be a JK or two away... :D here in the mountains of florida... i wonder, i'll be at such a high rpm it's going to kill me.
