HOW THE DURAHUB BEARING
The Durahub bearing protector is fully tested and proven to protect against damage from water and dirt entering the wheel bearings by sealing the area from outside contaminants. The Durahub creates a controlled environment around the wheel bearing by way of a flexible membrane, which maintains internal hub pressure by expanding and contracting, taking load away from the rear seal.
Durahub Extreme can be used with grease or 80/90W gear oil or combined 80/90W gear oil and grease.
With our unique clear lens, you can easily check it to see if your wheel hub is sealed. If you see water contamination or condensation on the inside of the lens, you need to replace your rear seal immediately before you have bearing failure.
