Swinger Air Problem

I was out riding today on my Giant VT, which has a Swinger Air 4-way on the rear. Part of the way through the ride, I noticed the suspension felt wrong so I lookled down and it appeared I was running about 55% sag. Since I put air in right before leaving, I figured I let out a bunch when taking the valve off or the temperature (a little above freezing) might have affected it (neither of these had ever happened before, but it was all I could think of).

Got back, took the shock off. It is stuck around 35% of the way through the travel. It will not rebound past there. The rebound is all the way out and the shock is holding air in the main chamber and the SPV chamber. If I blew the spring, wouldn't it be all the way dead and not be holding air at all? I put more air in and it seemed to extend a little, but not much. The SPV max is 150psi and it gets there fine. I don't know the main chamber max but I put almost 250psi in and it didn't seem to leak or anything.

Any ideas?

There is no travel adj. feature on the shock. There is a different link position that changes travel.

Anyone?

I put 300 lbs of air in there and it seems to keep extending but I don't feel safe putting more in than that.

I don't know about the swinger but Fox air shock use a self adjusting negative air spring. If something goes wrong with the negative spring it will get stuck part way through the travel. Sounds like this happened to you. A call to Manitou is in order.

I actually just saw this problem at my shop about a week ago. A kid came in with his Swinger 4-way air shock off of his Giant VT, and the shock was completely compressed and wouldn't rebound. I called Manitou to set up an RA and told them what the problem was, and the guy immediately guessed that the shock was from a Giant VT. Apparently this has been a recurring problem. Moral of story: call Manitou and they'll send you a new shock.
