This product is covered by a 1 year warranty from the date of purchase. In the rare event that a product does not perform as expected, Grand Rock warrants its prod­ucts against failure due to defects in materials and workmanship for the period specified under Terms and Conditions for the particular part. Grand Rock obligation under this warranty covers replacement of the failed part including transportation charges. The Length of Warranty for replacement parts provided under warranty coverage is the balance of the warranty period re­maining on the part being replaced. Grand Rock is not responsible for labor costs. It is important that the customer handle, store and install all products properly. This warranty does not cover failure due to misapplication, misuse, abuse, neglect, rust through and corrosion (muffler), im­proper service practices or non-approved modification. If you have any questions about proper handling, storing or installation do not hesitate to contact Grand Rock. Due to the higher heat output of Emissions Components, Grand Rock cannot warrant the Chrome Plating for any item installed on any truck made after 2007. As a solution, ceramic heat barrier coatings can be applied at an additional cost, alleviating the concern. Thank you, Grand Rock appreciates your business and understanding of any inconvenience this may cause.
