Cheers Daggie. Most other responses I've had (elsewhere) say similar things. I need to replace my suspension soon, and can get hold of a set for cheap, but have never used them before, so was trying to get feedback from others who had...

I don't think I will be investing in a set, no matter how cheap.

Its a common theme that they give a harsher ride than standard rubber across many cars, makes sense I suppose as rubber has more give, when I was restoring my Capri, I was strongly advised to stick to standard rubber bushes

Didn't Enzo Ferrari once say that the jeep was America's only true sports car?

Floflex polybushes sorted the death wobble on my WJ and made a huge improvement. I’d definitely recommend them over rubber.

Decent quality rubber bushes are the best choice. Some brands (Super pro springs to mind) of poly bush claim to be a bit softer but some are like plastic.

Cool - thanks for all the opinions. I've decided not to both with these for now though...

IMHO, they make for a harsher ride and don't last

I cant speak for them on a jeep, but I fitted them to an RX Turbo and an Escort Mexico in years gone by and they did NOT make the ride harsher - in fact the consensus was they made the ride more compliant... (and yes, they did improve turn in and general axle control / high speed handling as you would expect).
Others at the club reported the same thing.
Our invented rationale was that they allowed the pins to rotate more easily, ie. without initially sticking, which gave a more progressive, smoother start to suspension movement in the direction the suspension is supposed to move while preventing twists etc. in directions you didn't want things to move.
They definately improved both the ride and cornering and were not "harsh" at all.
