The manufacturer made point that this type of bushing is usually ordered by drivers with AirRide or other suspension modifications who demanded harder material, and they were pretty happy with the product. It's been on the market for over a year now. Personally i don't have too many questions about other items in the line 'cause they look to be very well made indeed.
In my situation with the stock ride height this puck bushing might not work in full travel range, just as Ben mentioned. If it had exact same design as the OEM one but only implemented in PU, i would have no hesitation 'cause Poly is just better material, besides it has all the required flexibility for the application, so no worries about premature failure here. At least not for my part )
Another point i agree on is that PU would not be the best choice for the spherical bushing introduced earlier, for it might well be too soft. PTFE would likely be a better bet, but then it's hard to say how the car would feel with it, thou i see this type is not uncommon with other brands:
This setup is popular with offroad drivers too.
If poly is just 'better material' then why does 0 OEM or professional race team use it, anywhere? Poly is cheaper to mold, and is harder. Thats it. Higher durometer rubber takes actual R&D money, and is cost prohibitive for most of the aftermarket. Thats why Groupe N rubber pieces are typically very expensive - economies of scale for low volume production parts that were run in actual racecars. There is nothing 'better' about polyurethane in a large majority of automotive applications. Science & physics disagree with you.
