Im running ARB air lockers front and rear in my SUT ....I love them!..but if i had to do it over again i think I would have just gotten the Eaton locker for the front . I only say that b/c i had a hard time finding somebody that ,after reading the install instructions, was confident enought to install them...and luckily for me i got a great deal on my ARB stuff b/c my install bill wasnt cheap. You're right about the lines , you do need to run them threw some braided tube lines and away from heat ..but once you do that they are amazing ..strong as heck. They do have one downfall though , happened once during a winter trail run where it was damn cold and we had been driving for some time so vehicle was hot and we stopped for a bit and my air lines must have build up some moisture inside and froze up on me ..had no lockers rest of the day till i got it in the shop and thawed out , then was fine again. I did save myself a little money also since i figured we were doing the lockers might as well change the gears to 4.88's ..which was the best thing i ever did...oh and yes i do have to say it is nice having the on board air to air the tires back up after a day on the trails and the ARB stuff is pretty nice stuff
