Perfect fit!
Complete set and very easy to install. Replaced the old ones with these new ones and trailer is riding smooth. Just made sure to grease up the bearings.

Good Hub but???
The hub was of good quality and a perfect fit. The bearings were ok. The cap and axle seal are not acceptable to be used on a boat trailer. The axle seal has only a single lip where a boat trailer requires a double lip seal. I ended up buying a bearing and seal kit made to be used on a boat trailer.

Great buy and product
Bolted right on no issues. Just wish it came with the spacer,washer, nut, and cotter pin since I wanted a whole kit. Great buy and product.

Hard to find where I live so being able to find someone that will ship up here to the great white north is huge. Very nice well made product.

Direct Replacement Hub (Year 11/2016) HF Trailer #62666
I spun M-12 lugs off hub (which rode on a 1” straight spindle) on Harbor Freight trailer #62666 (1,195Lb. Cap.) purchased in 2018. Harbor Freight was NO help in getting replacement hub. I purchased Martin hub (H4-C-Pb-b) and seal (TC30-50-10MM) from two different sellers on Amazon. Martin wheel hub arrived with damaged grease cap (I had old one off damaged hub). The Martin hub has no zirk fitting, the HF hub did. The Martin Hub fit perfectly on HF spindle and is rated for 1,250 Lbs. You will have to pack bearings (L44643 x 2) with grease. Hub fit perfectly on HF tire (4.80/4.00-12). Martin hub came with 4 lug nuts, lugs pressed into hub, 1 seal (apparently not the correct size), 1 cap (damaged), 2 tapered beatings. You need washer and castle nut from trailer (save old stuff, just in case). I ordered two hubs to have one as a spare.

Quick shipping and good value. Good replacement for my rusty snowmobile trailer hubs

Must pack the bearings, scratches on arrival
You have to pack the bearings and assemble the hubs yourself. 4 stars because there are others that come prepacked and ready to install. 3 stars because the hub came in scratched up and the other did not.
