There is some electronic braking in 4wd mode to keep both wheels spinning at about the same speed, but when it comes down to it you have to get the non slip option to have a limited slip rear differential.
Bought the Sahara without the non slip rear option last weekend and am loving it so far. Not a serious off roader so probably won't ever know the difference. Hope this little trivia tidbit helps those inquiring minds.
Track lock is a limited slip, clutch style rear diff.
"no spin" is what jeep calls it.
Available in all models except rubicon.
Also, the 4wd lever MECHANICLY locks the diffs together. The only electronics are downhill descent.
Salesman need hit with large heavy objects for the poor info they give out.
