I'm not sure thats 100% correct. I never took physics nor am i a suspension expert but from what i understand one side of the IFP is 100% fluid and the other side is 100% gas. Gas compresses, fluid does not. In its free state (not on the truck) the shaft should be fully extended and no empty space in the fluid portion of the shock. As soon as you compress the shock and the shaft moves into that chamber it displaces the fluid and the only place for it to go is into the IFP chamber so the IFP should move as the shaft moves, regardless of speed. Again, i could be wrong but thats how i understand it. An easy experiment would be to rebuild a rear shock, charge it to 200psi and leave the gauge on and install it on the truck and see if the pressure changes when you take it off the jack stands. Maybe I'll do that when i install my bump stop kit.
