High quality parts. Very fast response.

by

I don’t normally leave reviews but felt compelled. Within hours of ordering my parts I was emailed a photo of my parts with a photo of the invoice along with my tracking number. If you order performance parts often, you will know that this is unheard of. The parts arrived sooner than expected and are very high quality. Thank you Vintco!

Great Bearings and seals.

These are for my new engine I am building. I have used Vintco bearings and seals in my 1976 Yz250 framer and they work great.
