gas shocks

[nathan12]

What does increasing or lowering the pressure in the shock do to it?

the way it was explained to me is it acts like another spring. the more rod pressure the heavier the "spring".

I have been wondering the same thing. Increased pressure obviously increases compression but wondering about rebound and as JSF74 said how it might effect spring rate.

It is a pressure that basically varies by shaft position. The compression and rebound damping are not effected. However, enough rod pressure can overcome low levels of rebound damping where no force is needed to extend the shock at some shaft speeds.

I do know if I scale my car with the shock hooked up it adds lr bite.

If you ask a shock specialist what adding pressure does you'll most likely hear it either increases or decreases the feel of that corner. Also on the comment of having the shocks bolted on or off just simply bolting up your left rear gas shock will most likely be 30-40 lbs of added pressure to that pad. We prefer to scale without shocks due to the fact we use such extreme numbers these days it rarely gives a consistent reading. Some others have said scale your car as it hits the track but in our findings the car needs to settle for awhile and any movement of he car getting in and out or what not we never liked the numbers jumping around.

same here id chase my tail all day with the shock hooked up! my numbers are pretty crazy though.

In the late model world, removing your gas shock removes your spring. I would leave them on, but you do have to experiment and come up with a routine that proves you are getting consistent readings.

I always disconnect my LRF shock and back off my rebound or it would take forever to settle back to stable numbers on the scale. If you don't buy into it set your car on the the scales jack it up set it down note your numbers go inside get a beer and sammich and come back in 30 minutes and see if they are the same. Also don't scale with your garage door open we had a windy day and the air was hitting the spoiler and changing our numbers I kid you not.
