Product Description
The Cummins 3932339 OEM Throttle Linkage Control Rod Adjuster is the factory-correct adjuster used on 1994–1998 Dodge Ram 2500/3500 trucks equipped with the 5.9L 12-Valve Cummins. Installed on the mechanical throttle linkage connecting the accelerator pedal to the P7100 injection pump, this adjuster ensures proper rod length, smooth throttle movement, and correct pump actuation. Using a genuine Cummins adjuster prevents slack, binding, and improper fueling caused by worn or incorrect aftermarket linkage pieces.
Whether rebuilding your throttle linkage, restoring a factory-correct setup, or repairing worn hardware, the 3932339 adjuster provides OE geometry and long-term reliability for consistent pedal feel and precise mechanical control of the P-pump.
