This is a Genuine GORILLA-LIFT Cable and Quick Link Two Pack. Includes two Stainless Steel / Coated Cables and two Quick Links. IMPORTANT: If you have side rails that are 24-inches tall and/or are preloading tension over 25-inches above your side rail, you may need to order the Spring Assembly instead of just the Cable and Quick Link. Quick Link will reduce cable travel distance by 2.25-inches. Bolt cutters are required for removing the old cables. Please note that the shipping address provided MUST HAVE a mail receptacle. Any address provided incorrectly will be charged again for the original shipping amount and we will ship the product a second time to the correct address after contacting you. Thank you.
