Bolt in 9 inch housing with new 31 spline axles only. Does not include the third member or brakes (they are available on our other pages). This is a brand new housing and axles with the appropriate brackets already welded on. If your car or truck uses leaf springs, it will come with perches welded on in the correct location. If your car has a 4 link or 3 link, those brackets come welded on on in the proper locations. Pictures are for reference and may not be exactly what your car or truck need. Narrowed are available.
