Thanks for the info. I have no experience with a magnetic ride system. I understand the basics of magnetic ride. An elctro magnet is activated and aligns metal particles, suspended in fluid, inside the shock absorber, to create a more dense fluid, when needed, thus improving ride quality.
I have looked all over the internet for detailed schematics or some kind of design details for the magnetic ride system, to better understand the parts that make up the system, but have had no luck (I’m sure it is all proprietary info). So I do not know how the sensors actually work. I believe the electro magnet, that is activated to control the density of the fluid, is inside the shock absorber.
What I do not know is exactly what the sensors that are external to the shock do. If they activate this electro magnet in the shock then their position relative to the shock absorber would be the main concern. BUT I have heard that these sensors may monitor the road surface. If that is their main purpose, then lifting them at all (away from the ground) would affect ride quality.
I was under the truck the other day trying to get a feel for the system. It looks like the sensors mount to part of the truck above the upper spring mount. Therefore, leveling the truck with an upper spring mount spacer will raise the sensor relative to the shock absorber. A spacer on the bottom will lift both the shock and the frame of the truck, thus keeping the sensor in the same location relative to the shock absorber.
So basically depending on what these sensors do, would control if a spacer under the spring would work or not.
Maybe someone with more knowledge of how the system works can correct me or provide more details.
