    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.
