Overview

These polyurethane bushings are manufactured to be stronger and last longer than standard rubber bushings, improving vehicle handling and drivability. The sleeves in these bushings rotate freely, which enhances their longevity.

Show original supplier description

Unlike factory rubber bushings, these polyurethane components offer superior strength and longevity. PSB specializes in developing innovative suspension solutions that go beyond simple replacements to actively improve vehicle performance. The key features include sleeves that freely rotate to extend bushing life and a manufacturing process that uses the highest grade of polyurethane, with a durometer specifically chosen for the application. This leads to a product that significantly exceeds the quality and lifespan of original equipment bushings. Installation is also streamlined, typically taking between 1 to 5 minutes per bushing after the original components are removed. Polyurethane offers distinct advantages over rubber for suspension components. While rubber bushings have a limited lifespan and can contribute to suspension failure and rapid wear of related parts, polyurethane provides a more robust solution. By using PSB's polyurethane bushings, you can correct these issues and often experience improved vehicle handling and a more responsive driving experience. The brand offers a lifetime warranty on this product.
