Urethane PU Shock Absorber Block Bushings

Urethane has many benefits over rubber, especially in the consistently high-stress suspension systems in which bushings are often installed.

Urethane tends to have a higher load-bearing capacity, greater tear strength, better compression set, and greater abrasion resistance than rubber. It is also more tolerant of greases, oils, and ozone.

Rubber bushings tend to deteriorate rapidly with age. As rubber bushings become softer and more pliable, they resist the forces placed on them less and less. In a vehicle in particular, this reduced resistance leads to increased movement of suspension components, excessive tire wear, and braking instability. Polyurethane bushings can withstand the elements of the road for the long haul, while rubber bushings can not. When installed in a vehicle, urethane bushings offer more controlled alignment and steering.
