Overview:
The ARB Differential Breather Kit is engineered to prevent water ingress into drivetrain components during off-road water crossings. It replaces factory one-way breathers with a high-flow, zero-vacuum system to protect differentials, transmissions, and transfer cases.
– Vents up to four drivetrain assemblies from a central high-mounted manifold
– Prevents vacuum-induced water contamination during rapid cooling
– Uses large-diameter tubing to avoid clogging from oil displacement
– Compact, anodized billet aluminum manifold with splash-resistant air filter
– Mounts virtually anywhere above waterline for flexible installation
– Complete kit includes all fittings and tubing for a two-line setup
Specifications:
– Manifold Material: Anodized billet aluminum
– Breather Ports: (4) 1/8" BSP ports, (1) 1/4" NPT air filter port
– Tubing: 8mm polyethylene, 8m length
– Fittings: (4) 8mm–1/8 BSP push-in, (3) 1/8" BSP plugs
– Air Filter: Splash-resistant, high-flow
– Hardware: (2) self-tapping screws, (25) cable ties
– Compatibility: Suitable for use with drivetrain breather systems
Fitment:
See product title or contact support.
Notes:
Kit includes hardware and tubing for two assemblies, with provisions for up to four. Ensure manifold is mounted high in the engine bay or cab to remain above water during crossings.
