Dunbier bearing and seal sets are factory backed replacements and will perform to the highest standards. The bearings and cups are precision matched to ensure long life and high performance in testing conditions. Our seals are high grade and have proven over time to be a great choice for all boat trailers.

Marine seal (two part) kits are recommended for trailers that are using grease caps. If you are using bearing buddies, it’s important to not over pressurise the system and force the rear seal out of its carrier.
