MR-3440 is an OES rear left magnetic ride shock for the 2007-2010 Cadillac STS (GMX295 Platform) with All Wheel Drive (AWD) or Rear Wheel Drive (RWD) equipped with the GM magnetorheological damper system (Z95 RPO). This magnetically controlled shock from Arnott provides the same highly adaptive ride as the OE. The monotube damper is filled with magnetorheological fluid which is a synthetic hydrocarbon oil that contains iron particles that are easily magnetized. The damper includes two electromagnetic coils which, when turned on, instantly change the bonds between the magnetized iron particles to alter the viscosity and stiffness of the suspension.  Arnotts new magnetic ride Cadillac STS rear shock connects to the vehicles ECU with no modifications. WARNING: Cancer and Reproductive Harm.
