This is a cast iron fan pulley bracket that is a reproduction of the original 1991-1993 intercooled Dodge Cummins bracket. This is a huge space saver over the similar parts on most all 12 valve engines. Included are the cast iron bracket, bearing (installed in bracket), aluminum pulley, 4 bolts to install to engine, and 6 small bolts to install pulley. NOT included is the machined center hub. you can press your oem used hub out and install it in this new bracket and bearing. Later this year, we will offer this as a complete set with the hub included.
