This kit will extend the breathers on the front and rear differentials and the gearbox and the transfer case.

Raising the height of the filtered vents helps to prevent the ingress of water to the differential housings and gearboxes during water crossings.

QUAD Breather Extension Kit for use on 4wd vehicles.

Raising the height of the filtered vents helps to prevent the ingress of water to the differential housings and gearboxes during water crossings.

Four Ports to extend breathers on front and rear differentials, gearbox and transfer case.

This kit is universal and suitable for most four wheel drive vehicles. Vehicles without threaded housings may require 6mm rubber hose and clamps and a small amount of ingenuity to install.

It has all items necessary for Toyota and Nissan vehicles and other 4WD’s which have 1/8”bsp threaded differential housings.

In most cases the factory fittings on the differential housings unscrew and are replaced by the 6mm Push fit fittings in the kit.

We recommend you have your favourite 4WD Shop install QUAD breather kits for 2 reasons:

1. The gearbox and transfer case breathers are usually best accessed on the hoist.
2. Locating the breathers on the gearboxes can be difficult and they do not always have threaded ports, so the mechanic may need to use additional fittings or adaptive rubber hose.

The fittings are supplied with thread sealant already applied.

The manifold with the filters is easily secured to the firewall or anywhere under the bonnet with the included M6 Stainless Screw (and lock nut if required).
