quote:Bill advised their replacemnt shock has the correct pressure and it is maxed in the open position. He also said he it will not make any difference on the NAPA shocks to have the piston up or down, same pressure.
While I would not disagree that the vendors have likely done their homework/trials to come up with the correct pressure shock, I fail to see how a gas shock that is designed to hold the decklid open can be at max pressure in it's extended form. As the piston is forced back in the shock the gas will be under higher pressure i.e. in the closed position. Using the same deckild/body mounting points (bending moments) then nothing much has changed other than you have a gas strut that a vendor is standing behind to be of corrrect pressure for your application.
Did they ask you if you had a wing or fiberglass/CF decklid? All of these factors would affect the recommended pressure shock to use.
