Bottom line: if you prefer comfort, go for rubber. If you need performance, go for urethane.
Today’s subject is rubber versus urethane suspension bushings, and which are better. That answer depends on how the vehicle is to be used and what type of performance you desire.
Rubber Bushings
Rubber bushings are more compliant that is they have more give which allows for more sway and body roll and rubber bushings absorbs many of the roads vibrations and imperfections
Urethane Bushings
Urethane bushings on the other hand are nearly solid, and have very little give. Your ride will be firmer, much of the body roll and sway will be eliminated, and nearly every vibration will be felt.
Which Bushings Should I Get?
If you’re going for comfort go with rubber. If tightness and performance is what you desire, then urethane is the answer.
