Dorman 916-593 multiple displacement system solenoid for the 2011-2023 Ram 1500 and other vehicles replaces the factory cylinder-deactivation solenoids. In the multiple displacement system (MDS), the original plastic housings turn brittle from underhood heat and the oil passages clog with sludge. This Dorman OE FIX kit swaps in solenoids with metal housings.
- Kit of four upgraded solenoids
- Metal housing in place of the failure-prone plastic factory housing
- Compression-tested O-rings to restore the system pressure needed to deactivate the cylinder
- Quick-connect oval connector with electronic activation
Quick facts
- Part: Dorman 916-593 multiple displacement system solenoid
- Also called: engine multiple displacement system solenoid
- Fits: 2011-2023 Ram 1500 and other vehicles
- Material: Metal (housing)
- Condition: New
A failing original solenoid can bring on a loss of power, rough idle and lower fuel economy, and its fragile housing often breaks during removal. This kit has one solenoid for each of the engine's four MDS solenoids. Spark plugs, ignition coils or an intake leak can be behind a rough idle or weak power too, so pin down the cause before you buy.
Fits
The 2011-2023 Ram 1500, 2010-2023 Jeep Grand Cherokee and 2021-2023 Jeep Wrangler all fit it, and so do many other Chrysler, Dodge, Jeep and Ram models. Not sure about yours? Open the "Vehicles it fits" section and check your exact model and engine.

Frequently Asked Questions
Does Dorman 916-593 fit the 2011-2023 Ram 1500?
Yes. Dorman 916-593 fits the 2011-2023 Ram 1500. For another model, open the "Vehicles it fits" section and check your exact model and engine.
Does Dorman 916-593 include the O-rings and mounting bolts?
Yes. The kit has four solenoids, each with new O-rings, plus four mounting bolts.
Is the housing on this engine multiple displacement system solenoid metal or plastic?
Metal. The housing replaces the plastic factory housing that turns brittle from underhood heat.
Is the electrical connector on Dorman 916-593 a quick-connect type?
Yes. Dorman 916-593 has an oval, female quick-connect connector with two male blade terminals and electronic activation.
Why do the original plastic-housed MDS solenoids fail?
The plastic housings turn brittle from underhood heat and the oil passages clog with sludge. That can lead to power loss, rough idle and lower fuel economy.
