Suspension bushings are an important component of a vehicle’s suspension system, providing a cushion between the suspension’s moving parts and the frame of the vehicle. They can be made from a variety of materials, including rubber, polyurethane, and metal. Polyurethane bushings are increasingly popular due to their superior strength and durability compared to rubber bushings. This article will discuss how polyurethane suspension bushings can improve suspension performance.
Polyurethane bushings are more rigid and durable than rubber bushings, which means they can better withstand the stresses of the road. This makes them ideal for applications where the vehicle will be exposed to extreme conditions, such as off-roading or track racing.

Additionally, polyurethane bushings have less flex, which provides better handling and control. This improved handling can also reduce wear and tear on other suspension components, such as shocks and springs.
While polyurethane bushings offer many advantages, they also have some drawbacks. For instance, they can be more difficult to install than rubber bushings.
Additionally, they can produce more noise and vibration than rubber bushings. This can be a particular concern in street-driven vehicles, where comfort is an important factor.
Conclusion
Polyurethane suspension bushings can provide improved performance in certain applications, such as off-roading and track racing. They offer superior strength and durability compared to rubber bushings, as well as improved handling. However, they can be more difficult to install and can produce more noise and vibration than rubber bushings. For this reason, they are best suited for vehicles that will be driven in extreme conditions.
