We have what you need!

For EZ-Lube axles which are very common on boat trailers you want to use the Spindle Nut Kit for EZ Lube Axles part # RG05-100. This will have two nuts, washers and keepers.

For the non EZ-Lube axles use the Trailer Spindle Nut 1" part # 165686 and the Cotter Pin part # 165649. these are individual so you will want two of each to have all you need.

You can confirm these will fit on your axles by measuring your spindle and ensuring that your it has 1" threads on it.

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…
