Rancho RS9000XL Shocks

[afatouraee]

Hi everyone, Few days ago i replaced my stock shocks with Rancho RS9000XL Front(RS999288) and Rear(RS999269), Since then my car has started to vibrate above 50mph (even in the softest setting), Do I need to get an alignment or should I check for something else. And I thought these shocks are gas Charged but for some reason the front ones don't seem to have any gas as they do not rebound when pushed in. I would appreciate if you guys with the same shocks can let me know if this is how they are supposed to be and you experience with them.
Many thanks in Advance

I've been researching shocks because I'm going to level my H3 soon. From everything I've read, it seems to be unanimous that an alignment is needed after replacing the shocks. As far as the gas powered thing, I really don't know much about that.

Uh - no, an alignment is only necessary if you turn the torsion bars.


They don't rebound because they are not gas charged - it's normal.


On the street you should be running between 7-9.

Whoops, jumped to the conclusion of leveling.
