So a Rubi in 2WD is the same as my sport?

Panthermark is spot on.

As the Rubicon is meant to be the most offroad capable of all Wranglers, it comes with the most offroad oriented features--thus the lockers.

And the type of locker that is standard equipment in the Rubi is mutually exclusive of the type of LSD that is optional on the Sport/Sahara. There's only room for one in each differential ("pumpkin").

For this reason, an LSD-equipped Sport/Sahara is in truth a better winter weather vehicle than a Rubicon. An LSD is useful on and off the trail, whereas a locker is really only useful on the trail.

That's just one of the trade offs you make when buying a Rubi. Others include, for example, the gas mileage hits you take getting standard mud tires and 4.10 differential gears.

Depends on what you mean by "the same."

The Rubi will likely have 4.10 gearing and mud tires, neither of which (in its stock form) will be possessed by your Sport.

But if you're speaking only about traction assistance, then the answer is "yes."

Then yes.

Unmodified and in 2wd, a Rubi's rear differential and computer assisted traction programs will function exactly like a Sport.

Hmmm.....I would guess so but with BLD the poor Rubi can probably manage to get through the snow.

Of course it will manage, but in all honesty....outside of blizzard conditions where you are getting burried in 2 feet of snow, a Sport/Sahara with LSD and tires with sipes will do better on slick roads. Just like a Rubi with lockers and MT's will do better (better yet, easier) off road.

The Rubi isn't going to get stuck (and if it does, it can lock-up all 4 wheels), but things will be easier with LSD over an open diff.

Thanks for the info. I didn't even realize Rubi's didn't have LSD until panthermark mentioned something about it in post #57.

If you are buying a Rubi, you are probably doing some serious off-roading/crawling, so lockers (and the 4:1 transfer case) are more important than LSD.

In terms of hard-core off-roading/crawling, Lockers > LSD > Open diff.

I wish Jeep gave you the option to buy ala carte. I would have LSD in the rear (daily driving, snow/ice/rain), and a selectable locker up front (in case I even found myself off the beaten path).
they screwed us when they dropped the LDS/Lockers from the TJ Rubicon. I would still take the lockers over just LSDs though
