FAQ
WILL THIS FIT MY 1994–1998 12-VALVE?Yes—this bell crank lever is for P7100-equipped 5.9L 12-valve Ram 2500/3500 trucks.
DOES THIS WORK WITH VP44 OR COMMON-RAIL ENGINES?No—this lever is for the mechanical P7100 pump. VP44 (’98.5–’02) and common-rail (’03+) use different linkage.
IS THIS A GENUINE CUMMINS PART?Yes—OE Cummins 3931569 with factory geometry and durability.
ANY SPECIAL ADJUSTMENTS AFTER INSTALL?Confirm idle and full-throttle travel at the pump lever; adjust linkage to factory spec if necessary.
WHAT SYMPTOMS INDICATE I NEED THIS PART?Sticky throttle, uneven pedal feel, or failure to reach full travel often trace back to worn bell crank pivots/bushings.
