For 20 months and 6 days, we've been hard at work overhauling our polyurethane components - but who's counting? We are happy, no, we are really stoked to finally release our new SURE urethane.
Our new polyurethane compounds have a new chemical profile which increases tensile strength, heat resistance, tear strength, longevity, and overall performance - better yet, there are now 3 levels of hardness to choose from. What does this mean to you? With the addition of this new urethane, you're able to achieve specific performance results based on your individual driving needs.
We'd like to introduce our 3 levels of polyurethane hardness: Class 1 (Street Grade), Class 2 (Aggressive Grade), and Class 3 (Track Grade). We categorize these by horsepower level for each application, and factor in other variables such as use and driving characteristics. Whether you're a warranty-minded Mazda owner, or have a high-horsepower track setup, we offer a urethane option perfect for you. With a quick bushing swap, your mount is ready for the next stage of power. (Video: Rebuilding Engine Mounts)
