Gotta be locked!

Comments about ARB 4x4 Accessories Dana 30 Air Locking Differential:

I have ARB Air Lockers in my 04 TJ. I love the on-board air compressor that came with my setup. I was able to use my lockers the day after I got them installed at Browns Camp in the Tillamook State Forest. The only thing that I would change about the system is to be able to select which axle I want to be locked.

Comments about ARB 4x4 Accessories Dana 30 Air Locking Differential:

Works great and doesn't affect driving or turning when not engaged unlike auto lockers that affect how sharp you can turn. You never know it is there until you flick the switch.
