CUMMINS 3919683 OEM TIMING PIN HOUSING – RAM 5.9L 12-VALVE (1989–1998)

Product Description

The Cummins 3919683 OEM Timing Pin Housing is the direct-fit factory timing-port housing used on 1989–1998 Dodge Ram 2500/3500 trucks equipped with the 5.9L 12-Valve Cummins (6BT). This precision-machined OEM housing provides the correct seat, depth, and alignment for the Cummins timing pin, ensuring accurate TDC location and proper injection pump timing during service or rebuilds. Using a genuine Cummins housing prevents sealing issues, misalignment, and premature wear found in aftermarket copies.

If you are performing a P7100 pump timing job, top-end refresh, or complete engine rebuild, replacing damaged or corroded timing-port hardware with OEM Cummins components ensures a perfect fit and long-term reliability.
