If doing the Titan Swap on an Xterra or Frontier, you will need longer brake lines and to extend the tie-rods. This kits does both. Using our kevlar/stainless braided lines (long enough for even the most extended front coilovers) as well as our chromoly nickle-plated tie-rod extensions will save you the hassle of finding/building/machining your own. kit includes 2 extensions and 2 brake lines
