          Warranty Overview

          At eEuroparts, 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.

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

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

            • Improper installation, misuse, accidents, or modifications

          • 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.
