Sahara Difflock D44 front or rear?

Hi everyone,

I have a JKUS and i love it, its a great car. Family loves it too

Just wondering if anyone has any input on if it would be best to get a rear difflock or get a D44 with difflock for the front.. Its mostly for desert dune wheeling

You don't need the D44 in the front unless you plan on jumping the dunes. You can stilll get lockers front and rear without changing axles.

Lockers are generally for low speeds and it can break some to go too fast(more than 5mph on some) In dunes, like snow, momentum and wheel spin(not too much tho) are your friends. You want to be moving fast. Lockers might not be the best mod for high speed sand wheeling

Thanks guys, yeah I was thinking that myself that lockers aren't maybe that usefull in the soft sand. Probably why they don't import the rubi here. Thanks for clearing that up and appreciate the input.

Lots of awesome advise here in the forum

Cheers

If you plan to go dune jumping I would truss both the front and rear axles.

Is it OK to use stock D44 lockers for extended periods in sand? I find my stock 2012 JKU rubicon drives much straighter with front and rear lockers on when in sand. Been driving about 10 - 15 mph with them on while going a mile or 2 down the beach a few times. Are stock lockers just to get you out of trouble or are they ok to use like this?

4 jeepin, have got some good examples of strong trusses? And would I need to take them somewhere to get welded or can I get some bolt ons and do it myself? I never trussed the MK patrol I have and bend a diff housing on that once a long time ago..,

It is fine to use them like that, it gives you more traction in sand. Plus, sand is a very forgiving medium for lockers. So no worries, wheel away (you can even go faster if you want).

I disagree with the post above about not going over 5mph with lockers. There is nothing wrong with lockers and speed, as long as you are in a deformable medium and you aren't doing a whole lot of turning. For instance, climbing a sand hill might require speed and a locker together. No problem there, that is what it is for, but as soon as you return to hard terrain and you have the momentum you need, locker should go off.

Upgrading to a D44 shouldn't be necessary with stock tires, but if you plan on going bigger than a 33, you should look in to a Dynatrac ProRock housing (much stronger tubes and more ground clearance than a Rubicon 44 housing). At the magazine I work for, we did everything possible to beef up a D30 housing for use with 37s. In typical Jeep use, that housing is already bent. It all depends on the usage.

Here is the story on beefing a D30: http://www.fourwheeler.com/techartic...ive/index.html

The Rubicon E-lockers are limited to 18 MPH. You can go faster with aftermarket versions.

As long as you want. Max speed in 4L is 25mph. Max speed for rubi lockers is 18mph.
