The OSI Guarantee

Warranty Information

OSI offers the industry’s longest warranty – a full 4 months (or longer on some items) on all parts, both new and C2 Certified. Some parts suppliers, on the other hand – including OEMs – offer warranties of only 90 days on new and 30 days (if any) on used parts. Compare the two and it’s clear just how confident we are that we have the best quality parts in the industry.
