OEM-backed used engine coverage is available for trucks without an active base warranty or Extended Coverage plan. Extended OPTIMUM was designed by the Pros who built your engine. Unlike third-party warranty providers, we have no caps, deductibles, and liability limits.
Extended OPTIMUM for DD13, DD15, and DD16 engines can be purchased for 1 year/125,000 miles (201,250 km) or 2 years/250,000 miles (402,500 km) to protect your engine. Don’t drive another unprotected mile.
