You read it on the web so it has to be true? Have you ever held a set of PST bushing in your hand? If so, then you would know that your research was incorrect.

Having owned a full set of PST polygraphite bushings, I can tell you that they truly are graphite impregnated. Its easy to see the difference between polygraphite and polyurethane.

I can also say that after owning a couple of sets of polyurethane bushings that were installed with antisieze, I would never own a set again.

BTW- Retrofitting grease zerks are a great way to have a really nasty greasy bushing and nothing more. There is no cavity for the grease in the bushing, so the only way to get it remotely close to where it needs to be is pump grease in until it ozoozes out everywhere.
