You might want to call them about it and see what they have to say .Intended for use in extreme conditions, High Lifter’s bearings are double-sealed. They last many times longer than stock OEM and other replacement bearings.
The High Lifter Sealed Bearings have an integral rubber seal to protect them from contaminants and require no maintenance. They are further protected by the same external seal as the OEM bearing. This double seal will lengthen the service life dramatically at a cost equal to or less than the standard OEM wheel bearings. There are no other fully sealed bearings on the market designed specifically for Honda 4x4 ATVs.
