Yes. Every BOXI part is covered by a limited warranty against manufacturing defects from the date of delivery: 5 years on hood, trunk and tailgate lift supports, and 2 years on all other BOXI parts. The exact term for this part is shown in the specification table on this page. If a part fails within that period, email sales@tetronauto.us with your order number and photos and we'll arrange a replacement or a refund.

Use the Year / Make / Model search or match the interchange numbers listed in the product title and description before ordering — fitment is the buyer's responsibility. If you do end up with the wrong part, you can return it within 30 days as long as it is unused, uninstalled and in its original packaging. Not sure? Email sales@tetronauto.us with your VIN and we'll confirm the right part for you.
