WHAT is better, Urethane or Rubber (OEM)?
Rubber is the sap of trees found mostly in tropical climates. The sap is altered by mixtures of carbon (why it’s black) and mineral oils and various fillers. Polyurethane is completely chemical or man-made. Because rubber is a biodegradable product it is affected by ozone and will over time dry rot and degrade, while urethane will keep going and going. Urethane bushings will increase the performance handling characteristics of your vehicle. Urethane is a firmer material then rubber. It is more responsive then rubber. OE (Original Equipment) rubber bushings are usually softer and provide comfortable ride characteristics. Most OE bushings are rubber. Each type of bushing is suited well for the specific handling the user is attempting to achieve.
