These are direct replacements for the stock rubber crack-prone motor mounts. These feel just like stock but last much, much longer and can take the abuse of superchargers. Note, if running long tube headers, you may need to build a small heat sheild as most headers come very close to the mounts. If running a VK56 swap in an Xterra or Frontier these are the correct mounts for you, our Frontier/Xterra motor mounts will not fit.
