I have said this before, but here it goes again.

How many people do you know that have broken a LockRight?  How many people have you heard of that have broken an Aussie Locker?

One of the best differences is that the Aussie Lockers springs are softer so it engages and disengages more smoothly and easier.  Don't worry though, it stayed locked in Moab while doing 2 foot wheel stands so they work great!
