YOXUFA 40/41/420 Chain 48 Tooth Sprocket with 1" bore 1/4 Keyway Go Kart Sprocket Hub Parts

Note that the four nuts and bolts included are to small to properly attach hub to sprocket.

I made a makeshift go kart out of my old pressure washer engine. This sprocket is on the axel and it worked great. I cannot attest to the keyway holding strength, as I just welded mine on because my axel was a post hole digger, but it has functioned great and has no issue. Being able to screw and unscre the sprocket seemed like an extra weak point initially, but being able to move them independently made it much easier to weld into place in a tighter space, so I would highly recommend this over a solid one piece sprocket if you are planning to weld it. I am sure it would still be useful if you need room to get a key in there. I also like that I would not have to cut the full sprocket off if I have to replace it in the future for whatever reason.

Works great

Good quality, seems like it should last. Only issue was there were x4 8mm bolts included and the holes in the sprocket & hub are 10mm. Scrounged some bolts and nuts from my bolt bin and all is good.

It's okay, but the bolt holes are two different sizes and the included bolts are too small for either sized hole. The mount has 3/8" holes, the sprocket has a smaller metric sized hole, the bolts are smaller yet. I drilled out the sprocket to 3/8" and used 3/8 bolts, which solved the issue. Otherwise, it seems okay. After drilling the sprocket, it's not very hard steel, but its also not complete garbage steel.

Perfect fit

Worked well for me

The keyway in the hub is too small for a key to fit without being ground down.
