These Ford leaf spring hangers are for the front of the rear Ford leaf springs. Hangers will help support the leaf spring and link it to the chassis of your 2010 Ford Ranger or 1996 Ford F150 by mounting the Ford shackle of your leaf spring to the frame of your F150 in the rear while mounting the spring to the front frame. During time your OEM hangers may become worn out or damaged. When this happens it is very important to replace them.
