Thanks for the information Ryan. The Timken Bearing Kit item # TMK52VR is the correct one for your boat trailer. It includes inner and outer bearings and races, seal, cotter pin, and EZ lube spindle washer. This kit is sold per hub.

For a grease cap with a 1.98" Outer Diameter on a boat trailer, I recommend the Bearing Buddy Bearing Protectors item # BB1980A-SS, which are made in the USA. These are capable of being completely submerged and will keep water and dirt out of your hubs and bearings. They're sold as a pair and are a bit more in price than basic grease caps like item # RG04-020 but do a far better job of keeping water out. Plus they have a built in grease zerk that does not require their removal when you do routine maintenance.

What kind of boat do you have?

@RyanD. Timken is better brand than Chinese knockoffs brand, quality is what matters. I installed mine, no issues ride smoothly, not worried about burned out bearing and crack seals.

@RyanD. The bearings and seals in the set are Timken quality. I used these to rebuild both Vortex hubs on my boat trailer.

@RyanD I would not even consider anything other than Timken. Other bearings are vastly inferior. You might get away with different Chinese-made bearings for a light utility trailer, but for a boat or RV you should not compromise. The quality is worth the price!
