My shock absorber invention

Why do you think they'd be strong enough? 1000 lbs would require enormous magnets. Even with neodynum (say, Neo 42), you'd need large (10x10x8 inch) blocks of it. Neo also becomes less magnetic when it's warm (wouldn't do much sitting next to your engine), is highly succepible to corrosion, and a block this big is very difficult and expensive to make, even isostatically pressed.

For an coil to be powerful enough, it would have to be quite heavy and require a bundle of current. They also generate lots of heat, so some cooling would be neccesary, which requires more power than a car engine typically generates. Do you know of a way to run electromagnets of the required strength that could be powered by auto electronics? Just doesn't seem plausible to me...
