When you purchase replacement parts at any authorized Peterbilt dealership in North America, you will find most parts are covered by a one-year/unlimited mileage warranty.
If you install a warranted part and it fails due to a defect in materials or workmanship, the part will be repaired or replaced free by any authorized Peterbilt dealer. If a Peterbilt dealer installed the part, it will be repaired or replaced and installed free at any Peterbilt dealership.
Peterbilt Replacement Parts Warranty applies to most parts sourced through PACCAR Parts. Certain limitations and exceptions apply. See your Peterbilt dealer for details.
