It's pretty clearly PST's trade name for their stuff... Theoretically a graphite-impregnated urethane which results in a self-lubricating compound which actually makes a decent bearing surface...
Anybody have any experience with the Polygraphite bushings? Any better than the usual polyurethane-plus-thick-goo-which-washes-away-and-results-in-racket-and-binding?
marginally better. ive used energy, pst, and prothane.
of all of them, prothane with energys lube works the best for the longest without squeaking.
My sho has a ball & cup type of method using what you describe. It works, but it isn't perfect. Beats ruining the CC plates though. The cup is the top hat for my spring, and the ball is the graphite polymer stuff.
Thanks! Still pondering what to do on the Ranchero...
If you buy the black Energy Suspension ones they are graphite impregnated.
