If you have a hub that requires the protector to be threaded in I recommend the Bearing Buddy Bearing Protectors # BB1980T-SS, but if you just need protectors that you tap into the hub with a block of wood and hammer, then I recommend the Bearing Buddy Bearing Protectors # BB1980A-SS. Both of these will fit a hub with an Inner Diameter of 1.98 and are constructed of stainless steel which will help prevent corrosion. They have a grease zerk fitting to make it easy to add grease and a cover to help further protect against the elements.
