Found this to not be true with the JK models with the BLD. JL/JT would be the same.once a tire goes up in the air, they don't provide much help.
Correct, the BLD acts like the foot brake I described. However it's not still not going to help like an actual locker. Again if the OP wants it mainly for snow, mud, traction on mild-mod trails, go for it. If the OP is going to rock crawl and find themselves in precarious positions, a locker would be a better option. Don't get me wrong I loved it for what it was. Once I started rock crawling more, I found myself needing to winch. Put in a locker and bingo.Found this to not be true with the JK models with the BLD.
