This polyurethane bushing is the perfect replacement for a worn rubber bushing.

It has roughly the same load capacity as the rubber bushing, but produces slightly less vibration and lasts longer.

Fits all ASS motor mounts.

Now you can adapt your engine mounts to how you use the car.

Softer bushings for street and smaller/lighter engines and harder bushings for track/heavier engines.
Polyurethane has a better lifespan than rubber and is available in 3 different hardnesses, Shore A 70, 80 and 95.
The standard ASS rubber bushing is just below the purple (Shore A 80) polyurethane bushing in hardness but with less vibration and better service life.
See image with diagram to compare vibrations.

Assembly can be done by hand, but you need some kind of pressure to get the rubber bushing out.

A disadvantage of polyurethane is that it does not like heat, neither does rubber, but polyurethane melts if it gets too hot.
So keep in mind that the manifold/turbo must not be too close to the bushing, you may need to put a plate as a heat shield in some cases.

A set of bushings contains 2 complete bushings in 4 parts, 2 pcs stainless sleeves and assembly grease.
Keep in mind that some motor mounts have 4 bushings and therefore need 2 kits. For example. engine mounts for LS engines.
