The MBRP axle backs come with their own hangars and are designed to be a direct replacement. You will not need anything extra for the installation. Installation is easy, using a socket you undo the clamp behind your factory mufflers and pull the stock axle back out of the rubber gromits. To install the new axle back just reverse the process. You should be able to do it yourself if youve ever fixed anything on a car or even changed your own oil before, its simple and will actually take less time than changing your oil.
