Drivetrain Mounts and Upgrades for BMW 5 Series E39 (1996-2003)

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.

Enhance your car's performance with ECS Tuning's polyurethane transmission mounts, designed for both street and track applications. These mounts are engineered to withstand high torque and forced-induction scenarios, eliminating concerns about torn mounts and providing a more engaging driving experience. Although polyurethane may introduce some additional NVH (Noise, Vibration, Harshness), its exceptional durability, wear resistance, and resistance to water, oil, and grease make it the perfect choice for performance enthusiasts. ECS Tuning offers two durometer options to match your driving style, along with a comprehensive DIY installation guide, ensuring a complete solution for your transmission mount requirements.
