Long lasting bushes of a suspension kind?

[RoaryRati]

Given all the bushes talk reminded Mr RR came across some suspension bushes from Uxbridge-based Powerflex while watching Petrol Pep on YouTube. Has anyone come across them and if they do what they say is it worth further investigations?

For a 4200? It would be a no from me, the way the standard bush isn’t a rubber in shear design which is what powerflex and and the like do.

No from me too.

Manufacturers don’t use poly bushes for a reason.
Poly bushes aren’t designed to work in shear but the problem is they always end up doing so and start to disintegrate. Ok on a race car when you change them regularly but no good for the road. The only place a poly bush is suitable is where it’s being used in compression.
