No air lines to leak, break or compressors to fail, no cables to fray, no electric wires to break, the Aussie Locker gets you where you want to go, with maximum traction performance. You get 100% traction performance rather than 40-60% with a posi or LSD.
If you have a 4x a locker, any locker, should be your first mod if your doing any type of 4 wheeling.
This is a budget locker I installed myself and I works great and is very simple to install.
