California Residents: Prop 65 Warning


1 Year Warranty

USA Standard gear products are backed by a limited 1 year warranty against manufacturer defects.


Even though we recommend having your new gears or parts installed by a shop, that doesn't mean you couldn't do it yourself. Gears can be tricky to install and may require tools that most people don't have lying around their garage. If you have any questions or would like additional information, please give us a call.
