Rubi lockers only in 4wd LOW range

Am currently researching before buying my first Wrangler. I have read that the locking diffs in the Rubicon will only work in 4wd Low. I realize that this is a safety feature, but am wondering if it very often is a disadvantage. I've owned many 4x4 vehicles, but never had this restriction. Opinions please on the pros and cons of this feature.

Don't have a Rubi but my last vehicle was a Toyota FJ and it worked the same way. Locking diffs only in 4-Lo. Worked great.

I never realized this was abnormal.

Don't brake lockers work in 2-wheel and 4-high? I'm assuming that if the Sport has that feature the Rubicon does too?

He is referring to the axel lock option which is Rubicon only, not BLD.

Although not highly advised by some it is possible to "enable" through wiring lockers in 4 hi.

The BLD feature would be helpful in many cases. But it doesn't compare to real lockers in many offroad situations. Thanks.

Lockers in 4wd high are fine for people who have expertise in when and when not to use them. Rubicons are sometimes purchased by novices who have never experienced them and would be inclined to use them when contra-indicated.

Liability concerns hamper a lot of what automakers do and offer.

My point was that on a Rubi you'll have the BLD in 4-high and the true lockers in 4-low.
Aren't the lockers available only in low because driving any real distance because driving for an extended distance locked is hard on mechanical parts and wears on the tires?

Good to know that workaround is available.......though not from the dealer, I am sure.

Lockers used in a turn could prove fatal to novice drivers when the vehicle does not act as expected. The drivetrain and tires have no effect on the decision.

Not too many situations where you would need 4WH and lockers. I can see using it in mud where you would want wheel speed. Keep in mind when both are locked in your going to have a hard time steering it not to mention with more speed its going to push where it wants to go. Think about it. If its bad enough you need locked in then you should be going slow anyway.

Most electric lockers create a "solid axle". So the left and right wheel are forced to turn at the same speed. The differentials can't differentiate.

Simply stating, that means you cannot turn a corner when locked (where the outside wheel must travel faster).

So it's a safety hazard for novices.

a rear locker in 2 wd (rear of course) is pretty useful - that has gotten me out of more problems than 4 wd ever has.

Will the computer see that the lockers were bypassed on the newer models? I been doing research on this subject and it seems the lockers will disengage around 30 mph if you use a programmer. I hear they void your drivetrain warranty if you reprogram (please don't flame the warranty comment). I'm looking for a safe the safest way to engage lockers in 4hi and 2 hi but I haven't come across anyone that has done this on a newer model. I have a 2013 JKUR... So if anyone has experience with modding stock lockers via hardwire (bypass switch) could you weigh in here or send me a pm, that would be appreciated.

In what situations would lockers be used in 4Hi? I could actually see 2Hi being used before 4Hi.

Running through a long run of snow or mud where you don't need to drop it into 4L.

4L on a 4.10 rubi with the 4:1 t-case winds out at a pretty low mph.

I've installed electronic lockers on other 4wds with dash switches to instantly engage them when necessary.

I can see why the factory doesn't allow it (largely to prevent novices from wrecking by engaging them on road), but a skilled off-roader can certainly use it.

You can do it on a JK as well. Here is a PDF of the wiring diagram of the Rubicon lockers on a JK:

Are there any CONs to doing a manual switch? Like do you lose any features?

Probably depends on method used but shouldn't remove any capability. Just, as pointed out, potentially damaging if used unwisely and another item for a dealer to disallow warranty work.
