At GReddy we take our image seriously and back our products with a real warranty you can count on. In most cases, after examination of the item we will elect to give you a complete new product as opposed to repairing a defective one. We do this for two reasons, first of all to make you a completely satisfied customer, and secondly and warranty items are fully examined to find the cause of a defect and if necessary make running changes to the product line in the future. This is why GReddy maintains one of the lowest warranty claims percentage in the industry.
