Diff Breather Kit
You're driving hard or on the brakes going down hill. Everything is hot and what's at the bottom of most hills - Water. The sudden cool down can suck up to 1 litre of water into your diffs through the diff or chassis mounted breather. Or worse, if the breather is blocked (when did you last check it) the water will be sucked in through the bearings and swivel housing. You can not beat the laws of physics... From there it's all bad for your diffs axles, cvs, bearings, etc etc...
Also, no vehicles have filters on the breathers. This means the air sucked in (even without water present) is likely to be dusty. You don't want dirty air in your engine - why are the diff gears any different? This breather kit has filters to ensure the air that gets to your expensive diff gears is clean and dry.
This is what the competition boys do. Run a kit such as this to extend the breathing point to high up the firewall or higher if your rig permits. Some utes have them up on the roll bars.
Being flexible it does not break. It is soft enough to stretch a bit and withstand sticks and rocks under the vehicle.
Installation requires no special tools and takes about 15 minutes for the 2 lines. There is enough material supplied to do both front and rear diffs for conventional wagon size rigs. If you have an especially long or extraordinary application please let me know so I can allow for the extra length. The one kit suits all.
Here's a water tip. If you stop in a river for a look see avoid leaving your foot on the brake and allow the rig to move a bit. The discs cool rapidly in the cold water but the bit of disc trapped by the brake pad stays hot. With part of the disc being cold and the other part staying hot causes the disc to warp or even crack....
