(888) 312-8812 Login SignupWhen dealing with variable cylinder management in engines, the Mopar Engine Multiple Displacement System Solenoid Magnetic Ring Holder is a part that makes everything click into place. This part supports the placement and magnetic positioning of the Multiple Displacement System (MDS) solenoid, which controls the activation of cylinders during engine operation. Proper placement of the ring holder is important for accurate solenoid function. If you’re troubleshooting valve lifter issues, cylinder deactivation timing, or MDS fault codes, the Mopar 53022339AA is a practical fix.
