Sure, non-gas dampers need bleeding.

They have oil in the inner tube, where the piston runs, and an reservoir of oil in the outer tube, but there is air space to enable compression to take place when the piston rod (shaft) comes into the damper on the bump or closing stroke.

Now, usually they lie on shelves while they await fitment, or sometimes people will extend them on their side or even upside down... and they will thus either leak or draw air into the inner or functioning tube, past the footvalve.

The remedy is to close the shock while upside down, then invert it to the proper upright position (or at a slight angle, actually, is better) and open it. Doing this several times is good insurance before installation.

If my explanation isn't sufficient, just tell me where I have lost you... anyone? Without drawings it is somewhat complicated to get in mind...
