Should be said that there are conditions that can occur that will affect height, so won't necessarily always will it stay at set height if there is a failure.

1. Piston seal failure. If the seal fails, air can leak from one side to the other. Because initial lift requires more pressure, this is the side that will typically bleed into the other, causing the bike to continue lowering until equilibrium is acheived. Bad piston and shaft seal, you're going all the way down and staying there.

2. Bad solenoid. If the dump solenoid fails open, your shock will lose pressure from that side, again this most commonly occurs on the higher pressure, initial lift side, so again, bike will lower.

If you run long pipes, be careful if you notice it losing height gradually. It can be a sign of this type of issue and if the seal failure becomes catastrophic, your bike will immediately drop to lowest level. If you have long fishtails and don't catch it quickly or are not cognizant of actual ride height, you can drag pipes pretty severely in turns. Mine caught good, enough to lose traction at rear wheel, but I was able to recover.

I have it printed and in my tool box
