Prevents dirt, debris and water from getting in to your axle through the stock axle housing breather. Expands and contracts to accommodate increase or decrease in housing pressure. Kit includes one housing fitting, clamp and bellows (as shown). Easy installation takes just a few minutes. No hoses to route.

Vent Bellows allow your rear housing, transmission, transfer case, etc. vent without losing fluids and letting contaminates in. They fit over any 1/4" tubing or barbed fitting.

NOTE: DO NOT USE THIS ON YOUR STEERING RESERVOIR
The heat generated in most steering systems requires more expansion than these bellows allow, causing pressure to build up. A pressurized reservoir in your steering system is a VERY BAD thing.
