Talking Left a Rubicon X in the "dust" today. Snowdust!

Yup, once again proof positive that Jeeps are purpose built.

My JK Polar in snow conditions ate a JK Rubicon X alive today in CT. The poor Rubicon X just couldn't hold traction and momentum compared to an LSD rig on patchy snowy icy pavement. It sure looked nice though! , from my rear view mirror.

How is the Polar's traction different than the Rubicon's, other than different tires?

In snowy weather LSD is far more practical than Lockers on the street. Offroad tho, I would take lockers over LSD anyday. Eventually I will give up the LSD and do a rear locker.

Rubicons all have Open Differentials. Other models Wranglers may, if the option is ordered, have Limited Slip Differentials in the back which helped in this situation.

Dumb question but.... Can you have lockers on a LSD rear.

Talking

OK it was an old looking TJ with a snow plow, and 3 guys out of kicks and plow work, but I like to stir the pot



Nice weather we're having in CT, it'll be snowing for like 4 days!

Yeah that TJ didn't want to give up an inch of road so left them in the background at a stop light.

I'm not much for drag racing at all, but the LSD really works great for this kind of weather, and we're getting a lot of it this year! It's nice to be able to clear yourself from being around other vehicles from a stop light in slushiness. Gives you a little room to breath and LSD makes it happen. Applied carefully of course.

The way I read it is either or, not both. But I could be wrong. Need to see if someone with more knowledge pipes in.

Current generation of JK(U) it's LSD or Locker.

From what I have read, previous generation Rubicon LSD and Locker.

So if I wanted to add e-lockers to my LSD rear I could.

No idea...

But BLD with LSD is a very good offering, not a true locker of course. Only place you need lockers is places you need lockers!

Enjoy your Jeep, whatever the trim! and drive safely.

You would have to remove the LSD carrier and replace with a locker. Most selectable lockers operate as an open diff until you push the button. An auto locker like a Detroit fully locks when it senses slip with no buttons or wires - this can be scary on ice/snow in the rear and dangerous in the front. The Auburn ECTED serves as a LSD when unlocked and as a full locker with a push of a button.

I think eaton has a product that is a LSD that can lock (not as effective as a try locker because it just locks up the clutch, but better than nothing).

If it were me I'd probably lock the front and leave the rear LSD.

You cannot add a locker to a LSD since the LSD uses friction plates to control traction and they never lock up completely--

Nice post.

The Auburn ECTED has my attention now too, it looks like something I'd want in my rear axle, though it says it can be used for both front and rear axles with some exceptions.

Leading Manufacturer of Traction Enchancing Differentials & Planetary Drives - Auburn Gear

Per the chart for the Auburn ECTED on Quadratec you can't put it in a DANA 30 with larger than 31" tires though, so that's out for my Jeep, but the rear DANA 44 goes up to 35" tires.

I will be doing some more research into this one for sure.

Rubicons have electric selectable lockers.
So the axle is either fully locked or open.
You can't have a full and an LSD locker. Although most all JKs have BLDS that simulates a LSD by the computer utilizing the brakes to send some torque to the other wheel, but not as effectively as a LSD.
A limited slip locker like a Truetrac will send a percentage of torque to the opposite wheel that is not turning. But, it will not totally lock the axle.
LS good for loose dirt, some mud, snow and ice and not very good for climbing obstacles, rock.
Where you would not want a full locker for ice and packed snow on the road, but is great for the Off-road stuff.

It is my understanding that when folks install lockers it is best to do the rear as on non-Rubi's that is the stronger axle.

You didn't hijack it, you added to it, and I learned about LSD Locker offering from Auburn

For Factory current models it's true, LSD or Locker, but aftermarket appears to have both.

BLD isn't LSD simulation it's locker simulation... BLD's purpose is to make sure both wheels turn at the same speed on an axle. It doesn't care how fast or slow, just that they turn at the same speed.

LSD's job is to give the wheel that has grip more torque until the torque bias is defeated and then it breaks and turns like an open differential.

When LSD torque bias is defeated and it starts turning like an open diff then BLD kicks in.

LSD + BLD compliment each other.

Traction Control, that's the top level stability governor, but remember LSD is an additive traction, you can accelerate with it, while anything that uses brakes for traction slows you down.

Stock Rubi tires blow on compacted snow and ice. Not that I'd be racing you anyway. My AWD 4Runner (the V8 4x4s have full-time AWD- lockable Torsen center diff?) kills my Rubi in the snow BUT I also have ATs on the 4R and of course they are siped. So the tires are definitely better. Not sure if the AWD makes a difference or if it is a wash.

So do you think he was really trying to race you? There were two nuts out there racing on snow/ice?

Jeep TJ Rubicon has a full time limited slip rear which is selectable to full locker via air compressor. Just FYI your JK has no advantage there. Some of your fancy electronic traction control stuff may have been of some help however. Also, only idiots activate full locker when driving street in icy/snowy or any condition at all really. Makes your tires lose traction when you turn b/c they cannot rotate independently.

Except it wasn't a Rubicon TJ... It looked more like an old 4 cylinder

They also had a snow plow and 3 guys in it...

They almost had me!

Unless you own this Willy's you shouldn't start threads about drag racing Jeep's.

Congratulations on your win. Congratulations on your driving as I am sure it was the driver and not just the vehicle. I would bet if we switched drivers the X would smoke your JK Polar. It's the driver not the Jeep.
