DIY ARB Dana 30 27 spline 3.73 RD100.
Everything went well! directions easy to follow. I had put the rear lockers in last year, again with no issues. Would not attempt this if you have no mechanical ability and patients. You do need some special tools torque wrench, axel housing spreader, back lash indicator, heat gun.

Worth Every penny!
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.

Gotta be locked!
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.
