Progressive air shock problems

Postby t2oldbikes » Sun Oct 13, 2013 12:32 pm



One of my shocks has apparently blown its' top. One of the Progressive 412 air shocks on my bike is leaking out the top of the shock. It appears the aluminum housing has separated at the upper mount seal and the air is leaking out of there. Does anyone have experience with this and does anyone know if these shocks are rebuildable or repairable? It may have been going for a time as there was some leakdown prior to this but now it wont hold air at all. It does appear to be good for blowing bubbles with soapy water while hooked to a compressor but it doesn't ride very well.
Any idea what the life cycle is on these things? If it is only a few years and they are not repairable I'll go to spring shocks for a replacement rather than have problems with these. It looks like a major effort just to remove the upper mount with the racks in the way.

Eagerly awaiting a response on this one as well.

Just picked up a new-to-me older Aspencade today. On the way home, the rear shock low pressure light came on. The compressor isn't connected (seller disclosed this), so I CAREFULLY used a gas station pump. Well, within a short time the rear seemed to have lost most of the pressure.

The fronts on the other hand MIGHT be holding their air. Too soon to to tell.

They are definitely repairable and rebuildable, and Progressive sells kits with the bushings and seals to do it. If I recall, it's around $30 for a kit to do both shocks.

Thank you for the information. Was not looking forward to buying a new set of shocks.
Considering the potential work involved in everything I will probably shut it down for the season as the bearings need work and the disc looks like it may get replaced during the other work. Also have stainless brake lines to put on. Tools are made up and ready to go. If you're doing a lot of work on the back end may as well do it at one time.
Probably going to call the insurance and have it switched to my r75/6 and ride that a bit before it gets cold. Amazing how small it seems next to the Wing. To think it was the major tourer in its day!

Hi,

From what I have learned from Progressive lately is that the "Progressive 412 air shocks" are not air shocks but the 412's are mechanical with mechanical adjustments. The Progressive 416 are the air shocks. Can anybody confirm?
