1" Sprocket and Drum Mounting Hub

This hub stays at a 3 star for me and the only reason it makes a 3 star is because it's made from steel. As in my first review I mentioned the bolt holes not matching. The bolt pattern is 2 7/8" X 3 1/8" but on the 3 1/8 pattern the spacing between the holes is wrong. The first set of holes were 2 1/8" spacing and the next set was 2 5/16" apart. That means that I have 2 holes that will line up at the same time and the other 2 across will be offset. conclusion is, I will have to drill 2 holes out to make it work. This is my first bad part that I have ordered from this company so I will still use them in the future as my go to supplier. Love the company, the grade of products, and the fast shipping. This review is to reflect on the part itself and not the company. GPS has always delivered top quality parts. Thank You GPS and keep up the good work.

I ordered this part to upgrade my old Kart. When applying this to my other part with a 3 1/8 bolt pattern, they would not match up. I will update this review once I have the time to measure everything and make sure witch part is bad.

These worked well for my mini trike build. Only caveat is that there should be a lock screw at the keyway so the key won't slide out even after both lock screws are tight. The key can still move. Overall happy as I just peened the keyway channel to prevent key movement.

Great product and value it allows me to use bigger wheels for my trailer dolly!

Seams to be a good part. It’s nice and shiny.

Faster than expected Big bravo to sales people

it didn’t not fit

hub seems to work but i had to order it due to it missing from my first order which took them forever to send out after being told it wasn't in original shipment got tired of waiting told them i was ordering one i couldn't wait anymore then they sent one out so i have 2 so ones sitting on my shelf doing nothing wasted money

Seems well constructed and worked perfectly for my application. Loved the fact it came with bolts!

I got this hub for my universal split sprocket adapter. The holes line up just fine. But...The bolts included with hub are to short for the adapter. I have no idea what those bolts could fasten on to the hub but it would have to be made of thin 16 gage sheet metal. My adaptor isn't even .25" and the bolts only engage one thread. Disappointed
