Xero Limit Billet Battery Tray - 100% US Made and CNC machined. Though we designed this to be a direct bolt-in into an MX5 Miata 06-15, it will actually bolt into most cars thanks to our offset risers built into the tray. This allows you to drill the requisite holes for custom mounting from the bottom and bolt in using riv-nuts. NOTE: This is designed to re-use your factory j-hook. We provide a bracket that secures the battery to the tray via OEM or universal j-hooks. Custom fitment includes two M6 riv nuts that will allow you to secure them to any sheet metal surface.
