Stock suspension

since we got the gas pressurized shocks should they last longer than hydrolic shocks?

[Mad Dragon]

They are hydraulic.

I don't know about the others, but I'm thinking that the gas pressurized shocks last longer than hydraulic shocks.

Gas pressurised shocks, still have fluid in them (hence they are still hydraulic). Normal shocks absorb the motion by just moving a piston with holes through fluid. Gas pressurised shocks do the same thing, but in addition also have a chamber above/below the fluid that has a moving piston. On one side of the piston is the fluid, the other side a pressurised gas. If the fluid moves hard enough, it pushes up against the second piston, that in turns applies extra pressure against the gas.

The advent of gas pressured shocks was what allowed easy external adjustment, as you can vary the gas pressure to change the shock characteristics.

Very good read, definitely a great explanation of the benefits and disadvantages of different suspension technologies. :thumbup:

Past BMW OE dampers usually maintain their peak functionality for ~25 to 30K miles. After that they pretty much worn out and your handling will be significantly improved by new dampers, either BMW or aftermarket.
