Lockers

Have a JK sport with stock axles. I am looking into lockers for front and rear. Recommendations? And do I need to upgrade the axles? Thanks!

Do you need locker? are you rock crawling?
If your not rock crawling you might want to look at Eaton tru-trac front and rear. That's how I went, my jeep will go anywhere ( maybe not rock crawling) but anywhere else.

Yes. I am. A lot of the trails I'd like to run require lockers on the vehicle. It's my everyday driver but I take it off-road a lot.

I am also researching this, from what I have found by talking with people in our local club is they seem to prefer ARB air lockers over E lockers. One person with a Rubicon told me he has had to rebuild his front lockers twice, granted he spends all winter in Moab and uses his jeep a few times per week but that still seems excessive to me.

yep... wouldn't recommend anything but OX. the mechanical locker (cable driven). air lines pinch, leak, fail, electric - well there's always electric issues....

mechanical, it's basically a clutch cable off of a motorcycle... adjustment once, after stretching is all you should need.

far as upgrading the stock axles, yes. if you can afford to, buy a carrier that accepts larger spline axles.

for the rear:
buy 35 spline axles and a carrier (locker) that accepts 35 spline shafts (essentially you now have Dana 60 axle shafts)... if you truss the rear axle, it's pretty much as built as a Dana 44 is going to get.

for the front:
if you insert sleeves, i believe a 27 spline axle is as big as you can go. if you truss, you can go 32 spline i think....

i would be regearing now too if you haven't already done so. it's a pricey modification, but if you do it right, you only have to do it once.

On the D30 (front) you can get rid of the C clips (real weak spot) at joints with Cromoly Axles and go to full circle clips. That along with Rockridge sleeves and C gussets, you can make that 27 spline axle live. Talk to Erin at Rockridge 4wd you will not regret it. She will also give you expert advice on Locker choices and gear setups. The Lady knows her stuff and you get no (BS) sales pitch. Tell her your on the Wrangler Forum.

I have a new JK with the BDL. Because of that, I'm going truetracs front and rear when I regear. Do know that what one's definition of rock crawling and yours might be different. I play in all kinds of terrain, rocks included. There's nothing that truetracs w/ BDL won't crawl over where i'm at. Look up Uwharrie OHV

Front axles don't have C clips.

Edit: Unless you're talking about the clips for the U-Joints...

Before answering that, there are a couple of questions.

1) First and foremost, what is your budget? You can spend as little or as much as you want. There's no point recommending some lockers if they're way out of reach for you.

2) You've answered the question about what kind of wheeling you do.

3) What size tire are you running now and what size tire do you want to run?

4) What gear ratio is in your axle now?

5) How much daily driving are you going to do with your Jeep?

6) What do you really want to get out of your Jeep when it's all said and done?


You can spend a couple hundred on lunchbox lockers and have a pretty capable Jeep or you can drop thousands on upgrading everything while you're putting lockers in.

If you don't know much about the different types of lockers, start by reading here: The Basics of Differentials and Lockers

I guess I was not clear, U Joints with full circle retainers, I was not referring to c clip axles.

and the C gussets are for the housing. (Too dang many Cs)

I figured that out after I posted that.
