There are a few different bumper brackets listed here, choose the size and vehicle in the drop down menus.
The 1st Gen Xterra/Frontier brackets will work in conjuction with the OEM bumper brackets to achieve either the 1 inch or 2 inch lift that you need. They are UHMW Polyethylene and will come with new hardware to re-attach the front fascia.
The 2nd Gen Frontier brackets will raise the front bumper when installing a body lift on the 2005-2019 Frontier with the Chrome/steel front bumper. The brackets are powdercoated steel, and are cut to fit either the 1 inch or 2 inch body lift. The plastic/painted front bumpers on the Frontiers can be raised/slightly stretched around the crash bar so you will not need these brackets in order to do a body lift.
Hardware will be provided with brackets.
