    Warranty Overview

    At Newparts, we stand behind the quality of the products we sell. Every part we offer is backed by a warranty designed to give you peace of mind and protect your investment.

    Standard Warranty – Most Parts

    • Coverage: 2 years or 24,000 miles (whichever comes first) from purchase date.

    • Protection: Defects in materials or workmanship under normal personal use.

    • Eligibility: Applies only to the original purchaser and the vehicle where the part was first installed.

    • Exclusions:

      • Wear-and-tear items (brake pads, filters, bulbs, wipers, etc.)

      • Commercial, fleet, rideshare, off-road, or racing use

      • Improper installation, misuse, accidents, or modifications

    • Not Covered: Labor, shipping, towing, or incidental costs.

    Bison Performance Warranty – Our House Brand

    • Coverage: Limited Lifetime Warranty for as long as you own your vehicle.

    • Applies To: All products sold under the Bison Performance label.

    • Premium Protection: Goes beyond our standard warranty — if it’s a Bison product, the 2-year/24k mile limit is replaced with lifetime coverage.

    • Exclusions: Same as the standard warranty (normal wear, commercial use, improper installation, etc.).

    • What’s Included: Replacement of the defective product (labor and shipping excluded).

    Warranty Claim Requirements

    To keep claims fast and fair, we require:

    • Proof of purchase (invoice or order confirmation).

    • Photos or videos showing the defective part, order number, date, VIN, and odometer reading.

    • Diagnostic reports or part returns for non-visible issues may be requested.

    • Claims must be truthful, properly documented, and reflect normal consumer use.

    Buy With Confidence: We back our products because we believe in their quality, with a transparent, customer-first warranty process you can trust. And with Bison Performance products, you’ll enjoy Limited Lifetime protection—an assurance few brands can match.

    For full details and exclusions, please see our complete Warranty Terms & Conditions.
