ARB offers a breather kit that acts similarly to a snorkel for your differentials, gearbox and transfer case. The ARB Diff Breather Kit is primarily a hub that transfers air in and out of the critical vehicle components; the kit includes a length of air tubing that is run to a high point (usually under the vehicle’s bonnet) where it is most protected from dust and water ingress when drawing air back in. Out of the box, the four-port ARB Diff Breather Kit can be connected to all four key components (front diff, rear diff, transfer case and gearbox) and comes with enough tubing and fixtures to connect to the most common application of two differentials. With a small amount of additional tubing and fixtures (sold separately), the one kit will also accommodate your transfer case and gearbox. The ARB Diff Breather Kit is affordable and extremely simple to install. A small investment for full peace of mind and protection for your pride and joy. NOTE: We have additional tubing and fittings available if required.
