Magnumatic Air Shock.

I was servicing my 1500 I bought a couple years back. I was curious as to why the shocks weren’t holding any air, although the bike seemed to ride well enough. When I opened it up,I discovered the shocks were made by Magnumatic. I don’t know anything about them, can’t find a manual, don’t even know if they’re working correctly. Anybody have information or a manual that would let me know what to make of these?

Looks like that could be a Progressive Suspension moniker. Give them a call with any and all info you have. Probably long out of production, but rebuild kits might still be available.

Thanks. They are progressive shocks.

I was surprised that they still used air.
