1980A-SS - USA-Made Stainless Steel Bearing Protector w/ 19B Bra & Blue Grease Indicator - Wheel Bearing Protectors for Boats, RVs & More - Fits Hubs w/ 1.980” Inside Diameter (2 Pairs)

Using a piece of 2 X 4, Caps went easily on a tandem axle flatbed trailer axles and to date, have stayed in place over a 1000 miles of use. Caps allow topping off grease easily and perform as designed.

Fast shipping. Great product. Eases my mind when trailering boat to the coast

Easy to install.

Came as ordered and fit well. Replaced older style on my boat trailer that I broke taking off to replace bearings.

Worth to put on all trailers you have to prevent hub bearing failures w/ regular topping of grease.The integrated indicator shows when to add grease.

I really like the blue indicators letting you know when the grease is full. but, one of the units fell off of my wheel during use. so, expensive replacement and I'm nervous the next one will stay on. manybe use some loctite?

I put these on my utility trailer, an my motorcycle pull behind camper, they were easy to install and will make greasing my bearings simpler
