Ever been on the trail and ripped, tore or even burned a hole in an ARB locker air line? Well no matter how long you wheel, someone in the group will eventually damage their air line to their air locker. Nobody wants to be on the trail and be stuck without the use of their locker. This kit comes with 2 splice push fittings, and 2 lengths of air line. One is 12" long and thos other is 24" long. Easy to install, just cut out the bad part of the air line and splice in the 2 fitting and one of the air lines.
