Review on ARB 170112 Kit: Enhanced Differential Axle Breather for Optimal Performance in 4WD Vehicle's Drivetrain Assemblies, Differentials, Transmission, and Transfer Case by Jack Ford

Similar to other larger more expensive brands but offers the same features. Installation was easy, although no instructions were included. It's not too difficult to attach one end to the rear differential, run the included hose to the front of the truck, and bolt the filter to the firewall. However, I would like to warn you of a concern that the hose fittings are not made of high-strength steel. I cut one of these into the diff when installing and didn't even put that much torque on the wrench when installing. So be careful and take it slow. I just stopped when the threads stained with threadlocker were gone, but not completely.
