As opposed to traditional suspension systems, MagneRide has no mechanical valves or even small moving parts that can wear.
[4][5] The dampers are filled with magnetorheological fluid, a mixture of easily magnetized iron particles in a synthetic hydrocarbon oil.
The strength of the bonds between the magnetized iron particles causes the effective viscosity of the fluid to increase resulting in a stiffer suspension.
Generation II MagneRide continued to use a single electromagnetic coil inside the damper piston.
Changes from the previous generation include uprated seals and bearings to extend its application to heavier cars and SUV's.
With the single electromagnetic coil, there was a small delay from when the ECU turned off the current to when the damper lost its magnetic field.
