Warranty Information
New parts are covered under the original manufacturer's warranty. Rebuilt and used parts come with an inspection-only guarantee unless otherwise stated. While RF Engine is not the manufacturer and cannot extend additional warranties, we're here to help if any issues arise — including support with manufacturer warranty claims.
We guarantee all parts to be as described and in usable condition, free from misrepresentation or material defects. If something isn't right, we'll work with you to make it right.
Used parts are cleaned and inspected, but may show normal wear, surface rust, or cosmetic imperfections. Most will require further cleaning or machining prior to installation. We strongly recommend installation by a qualified heavy-duty diesel mechanic.
