Fit my 4x8 utility trailer as a replacement for a bearing that went bad. Install was straight forward, I ended up using the larger bearing and seal. Parts appear to be good quality and price was very fair. I installed greasable dust cover to make maintenance easier.

I measured my spindle and the hub I was replacing so I knew the dimensions were correct. Really nice that it came bearings and grease seals for 1" and 1-1/16" spindles. Perfect fit and great product.

Bought this set for a small 14' double wide jon boat trailer....materials seem to be worth the $$...nothing fell apart during install, no problems with install. Trailer never goes down highway or more than 10 miles in any direction really-so this kit was perfect for my needs at the price point. WOULD PURCHASE AGAIN

Bought a 1992 calkins trailer with my new to me boat from the same year.... I suspect 30+ years of neglect and disuse had taken their toll... both wheels when jacked off the ground had play and the grease that was present resembled forbidden pistachio pudding. Bearing races and rollers were heavily pitted. Option 1 was to replace bearings and races and use the same hubs, but these hubs did not have notches to make hammering out the races 'easy.' Saw these on Amazon, and ordered. I was able to do both sides in the dark, and in below freezing temperatures in about an hour total. Grab some 1.980 bearing buddies while you're in there. Highly recommend.

Easy to install after I refreshed my memory with a YouTube video.
