{"product_id":"polyurethane-bushing-set","title":"Polyurethane Bushing Set","description":"By decreasing deflection in the suspension system, these polyurethane bushings directly contribute to improved handling, sharper driver feedback, and reduced tire wear. Powerflex employs its own premium polyurethane compound, carefully formulated to deliver minimal NVH (noise, vibration, and harshness) while ensuring significantly greater longevity than standard rubber components.\n\nPowerflex offers its bushings in three durometers: Yellow (70A), Purple (80A), and Black (95A). Unlike other manufacturers who might use a single urethane grade across all applications, Powerflex's design engineers strategically select the appropriate hardness for each specific location. This ensures the required movement or rigidity is achieved without introducing excessive unwanted NVH. The hardness is standardized for each fitment, simplifying the selection process for street applications. For dedicated track or autocross use where NVH is a lesser concern, optional stiffer Black Series bushings are available.\n\nThis PFR5-411X2 set is compatible with a range of BMW E8X and E9X models, including various trims of the 1 Series (E82\/E88) and 3 Series (E90\/E91\/E92) from approximately 2006 to 2013. Specific fitments include models such as the 128i, 135i, 1M Coupe, 325i, 325xi, 328i, 328xi, 330i, 330xi, 335d, 335i, 335xi, and M3, with varying engine configurations like N52, N54, N55, M57, and S65. It is crucial to verify fitment using the vehicle selector or by consulting the detailed fitment table provided, as specific positions within the suspension (e.g., inner\/outer trailing arm, toe arm, guide rod) may vary.\n\nInstallation is recommended with Powerflex Copper Grease (PCG1) for ease of application and periodic reapplication is advised to maintain squeak-free performance and extend the lifespan of the bushings. Powerflex confidently backs its products with a lifetime warranty for the original purchaser.","brand":"Powerflex","offers":[{"title":"Default Title","offer_id":52663310123320,"sku":"PFR5-411x2","price":121.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687527015.jpg?v=1784325822","url":"https:\/\/store.motormia.co\/products\/polyurethane-bushing-set","provider":"MOTORMIA","version":"1.0","type":"link"}
