Suspension bushes made of polyurethane. PUR material is more durable than conventional rubber, often used in car parts. For off-road vehicle PUR is more suitable material because of the construction of bushes and arms in off-road vehicles. Construction of polyurethane bushes Escape4x4 is different - bushes wrapping is vulcanized to the outer edge (sleeve) - therefore there is no ripping of bushes out because bushes are only molded into the sleeve of the arm, not glued. Inner metal sleeve is molded as well. Polyurethane is 10 times more durable than conventional rubber. We also offer a choice of hardness, you can choose tougher bushes when using greater offroad tires or choose softer bushes for example in leaf springs.
