Outer Limits 4x4 Board

Hi, I'm considering adding a diff lock in the front diff of my Challenger. Since the LSD in the back is praised by everyone and I'm probably more likely to lose traction of a front wheel lifted due to the IFS, I guess it makes more sense to fit it at the front. Anyway, the only options I could find for it are the ARB air locker and the Lokka automatic locker. The lokkas seem to be much cheaper and by reading their sale speech on their website, they're the best. I don't think that's this simple so I ask you the guys the question: What should I do, pay more for an ARB or not getting ripped off and get a lokka? I don't want to fork money just for a brand, but at the same time I don't want to buy a locker that will give me problems in the long run.
Thanks in advance,
SLY.

ARB

Just put mine in the rear (ARB) and like you if I had an LSD in mine it would have gone in the front. I believe the Lockrite will give you a better degree of steering if you choose it and at half the price of the ARB diff lock. Go get one and let me know if it's any good

Don't fall for the ARB carp. (That's right, I said carp).

Make sure you buy a heap of spare pins and springs

Remember that with an ARB (and a Detroit) you are getting a much stronger replacement diff centre the extra cost is here.
Compare apples with apples.
The Lokka only replaces the side gears with a set of locking teeth and as such is not a strength upgrade.

Does that mean the Lokka unit is often breaking down and need fixing? How reliable would it be. The last thing I want is for the front diff to die on me in the middle of nowhere and no way of getting back home without front wheels driving.

OK, sorry for my ignorance when it comes to mechanical knowledge, but do I really need to get more strength in the diff?

I read good stuff about the Detroit, but unfortunately they don't have anything for the Challenger.

At $25 for a replacement set I can live with that. (As opposed to $600 minimum for servicing the ARB unit).

It's very reliable. In my circle we would have at least 10 (?) lokkas installed and not a worry. These are installed in both front & rear applications.
