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.

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.

I have a 2015 Toyota Tacoma Trd Sport and I was wondering if this locker will fit in my truck for front and rear locker?

Asked by CJ from on

Hello Depending on the gear ratio the front would use the RD111 or the RD121 and the rear is the RD129 Thanks

Answered by Rody from on

By 3.73 and up do you mean numerically higher? Or higher gearing? I want to install this in a JK dana 30 front diff with 4.56 motive gear ring and pinions.

Asked by Shep from on

Hello Yes 3.73 and up to 538 gears so this is the correct unit for your JK. Thanks
