I recently upgraded my cars suspension with these Energy Suspension bushings and I couldn't be happier with the results. Thanks to my knowledge gained in practice, I picked these bushings for their durable polyurethane material that reduces noise and vibrations. They helped improve the handling of my automotive machine and provide a smoother ride overall .The installation process was relatively easy, but it took some time due to the nature OF the parts. The only con I have is that they are a bit more expensive than regular bushings but the performance improvement is worth it..
