Marmon-Herrington offers customers a 12-month or 12,000 miles warranty for axle systems used under normal service. All of our service parts are manufactured to the same quality standards as production installed parts, whenever available.
All warranties become effective when the Warranty Certificate is returned to Marmon-Herrington. Service parts are warranted for 90 days or 5,000 miles. For overseas vehicles, we'll determine the defects and obligation at our facility in Louisville, Kentucky and then ship the replacement part to a distributor for installation. Marmon-Herrington offers no warranty on the original manufacturer's chassis components, not related to modification work.
