Real Coilover Question / pics included

Post by 72nismo1 »

Hey Fellas my question is regarding the shock in the rear coilover.
When you dissemble the spring and compress the shock is it supposed to come back up like regular shocks?

I was told they don’t work like normal shocks.
Im talking about older version coilovers set ups. No rebound adjustability on them.

Anybody know for sure?

Thanks

Depending on how old, if it is NOT a gas shock...it will not come up by itself.

"Normal" is a relative term, just depends on when the shock was made and if it was a gas shock.

Something like my KYB's in the back of my car have approx 50 lbs of upward pressure.

What brand are they? There are a lot of different ones out there.
If no one from the future comes back to stop you from doing it then how bad of a decision can it really be?

To answer your question, by the very nature of the "gas" charge, the shock will always got to full extension when free of mounting.

Only caveat to that would be if the shock leaked of course.

A gas shock is also hard to push down, due to the pre-load of the gas. A "normal" shock on bump would go down quite easily, roughly speaking.

Rebound is usually a lot firmer, to pull the shock to full extension, hence the fact that getting our so-called perfect bump/rebound ratio of 50/50...for the rear...is not provided my most shocks.
