ECS Tuning's Polyurethane Transmission Mounts are designed to address the vital role of transmission mounts in your vehicle's suspension. The factory mounts are notorious for failures that can result in over-revving, mis-shifts, and in extreme cases, potential chassis damage. Our polyurethane mounts provide a robust solution, engineered for both street and track applications, guaranteeing enhanced performance while eliminating concerns about torn mounts.
Polyurethane stands out with its exceptional toughness, durability, and impressive wear resistance compared to rubber. It also exhibits resistance to water, oil, and grease while retaining its original shape even when subjected to significant compression. By reducing deflection, polyurethane facilitates effective power transfer. While there may be a slight increase in NVH (Noise, Vibration, Harshness), the benefits far outweigh this minor compromise in ride comfort. With a polyurethane durometer of 70A, our street mounts are versatile, offering both daily driving comfort and track durability. For more track-oriented enthusiasts, we provide stiffer mounts with an 80A durometer rating.
For a hassle-free installation, we supply a comprehensive DIY guide. ECS Tuning ensures that you are fully supported from start to finish.
Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.
By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components.
Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.
Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.
