Arnott MR-3442 Rear Magnetic Ride Shock

Arnott MR-3442 is an OES rear magnetic ride shock for the 2004-2009 Cadillac SRX with the GM magnetorheological damper system. It restores the adaptive rear suspension behavior expected from the original equipment setup while connecting to the vehicle ECU without modification.

Key Features

• Standard-grade suspension shock absorber for the rear position
• Monotube damper design with magnetorheological fluid
• Electromagnetic coil control changes damping response in real time
• Direct ECU connection with no vehicle modifications required
• Fits 2004-2009 Cadillac SRX, rear, with Magneride RPO codes FE3 F55

Product Details

The Arnott NEW product line focuses on replacement suspension components built to match OE function and vehicle integration. MR-3442 uses magnetorheological fluid, a synthetic hydrocarbon oil containing iron particles that respond to magnetic fields. When the coils are energized, the fluid’s viscosity and damping stiffness change quickly, allowing the rear suspension to react to road conditions and driving inputs. This part cross-references Cadillac 15145221 and 19302764 for the same application. For buyers searching for a Cadillac SRX rear magnetic ride shock or an Arnott MR-3442 replacement, this unit is built for the GM GMX265 platform with Z95-style magnetic ride control applications.

Common Issues Addressed

• Rear shock leakage or loss of damping control
• Excessive bounce, harshness, or unstable ride quality
• Warning lights or suspension faults tied to the rear damper
• Uneven rear suspension response during cornering or braking
• Reduced performance from worn magnetic ride components

Installation Notes

Fits 2004-2009 Cadillac SRX, rear, with Magneride RPO codes FE3 F55. Confirm the vehicle’s suspension code and rear-position application before ordering. Arnott MR-3442 connects to the ECU without modifications, which supports a direct replacement process for the original rear magnetic ride shock.

Quality Assurance

Arnott supplies OE-style replacement suspension parts engineered for electronic ride-control systems. MR-3442 is built as a magnetic ride shock absorber for direct integration with the factory control strategy on the Cadillac SRX.
