The Cummins 3936256 is the genuine front timing gear housing for 1994-1998 Dodge Ram trucks with the 5.9L 12 valve Cummins and P7100 injection pump.

It is the common repair after a killer dowel pin backs out and cracks the original housing. Replace it with a new crank seal, gasket and a secured dowel pin.
