Arnott Industries MR-3445 rear left shock absorber for the 2009-2015 Cadillac CTS changes its damping with magnetorheological fluid to control ride. The monotube damper gives the same highly adaptive ride as the OE magnetic shock.
- Precision-tuned shock absorber for ride control
- Made for the magnetorheological damper system, RPO F55
- Monotube damper filled with magnetorheological fluid, a synthetic hydrocarbon oil with easily magnetized iron particles
- Two electromagnetic coils that change the fluid's viscosity and the suspension's stiffness when turned on
- Connects to the vehicle's ECU with no modifications
Quick facts
- Part: Arnott Industries MR-3445 shock absorber
- Also called: suspension shock absorber
- Fits: 2009-2015 Cadillac CTS

Yes. Arnott Industries MR-3445 is the rear left shock absorber for the 2009-2015 Cadillac CTS, and it is a direct replacement for the GM magnetic shock.
What fluid is inside this magnetic ride monotube damper?
Magnetorheological fluid, a synthetic hydrocarbon oil that contains iron particles that magnetize easily. Two electromagnetic coils change its viscosity when turned on.
Does this magnetic ride shock need modifications to connect to the ECU?
No. The Arnott Industries MR-3445 connects to the vehicle's ECU with no modifications.
How can I tell a magnetic ride shock is worn out?
A harsh or floaty ride, fluid leaking from the shock body or a clunk over bumps can mean a worn shock. A shop can test the magnetic ride system itself.
Does the Arnott MR-3445 replace number 19302784?
Yes. 19302784 is one of the numbers this rear left shock absorber replaces.
