Drivetrain Mounts and Upgrades

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.

Key Features:

• Minimized transmission movement, reducing the risk of mis-shifts and over-revs.
• Made from high-quality polyurethane bonded with 304 Stainless Steel.
• Enhanced driving experience for both street and track enthusiasts.
• Two durometer options available: 80A for race applications and 70A for daily driving (ES#2859359).
• Replaces weak OEM mounts.

Enhance your driving experience with ECS Tuning's Performance Polyurethane Differential Bushings. These meticulously engineered bushings offer a direct connection between your right foot, the engine, and the chassis, making them an essential upgrade.

• Say goodbye to the softness of factory rubber differential bushings that absorb vibrations and reduce performance.
• ECS Tuning's polyurethane bushings eliminate the deflection found in factory rubber bushings, resulting in improved power transfer from the differential to the wheels.
• Experience enhanced throttle control, whether you're navigating a challenging canyon road, drag racing, or simply commuting.

Unlike delrin or solid differential mounts, these bushings deliver improved performance without introducing harshness or excessive vibration.

Crafted from durable 88A durometer polyurethane and enhanced with a black anodized 6061-T6 aluminum sleeve.

Resistant to chemicals, ozone degradation, road salt, and general wear and tear, ensuring a longer service life.

Urethane mounts keep the differential from twisting under load. As torque is put through the driveline it causes anything to twist and move. The differential is mounted to the subframe and the twisting and deflection can be transferred to the rest of the chassis. With a stiffer mount the differential will not deflect as much. This improves seat-of-the-pants feeling to the driver, giving more feedback for smoother power delivery. In theory, there's also more torque being sent to the drive wheels since it's not being used up shifting the diff weight around.

These are tough 88A durometer urethane bushings with a anodized almunum center sleeve, engineered by ECS. This is a set of E36 diff bushings - 1 for the front and 2 for the rear cover. New high-grade hardware is included (the front bolt has a tendency to snap from all that torque twisting!).

Your rear differential is indirectly connected to your right foot through the engine and driveline, and connected to the seat of your pants through the chassis. Soft factory rubber differential bushings absorb vibrations between chassis and differential, providing comfort and softness in both of these connections.

Enter ECS Tuning's In-House Engineered Performance Polyurethane Differential Bushings. By eliminating the deflection factory rubber bushings permit, the connection between your right foot (and your seat) to the wheels is improved. Removal of this slop allows for crisper power transfer from differential to wheels, which means better throttle control while carving a canyon road, drag racing, sliding the rear end out, or just driving to work. This is achieved without the harshness or vibration associated with delrin or solid differential mounts.

Featuring a tough 88A durometer polyurethane and Black anodized 6061-T6 aluminum Sleeve, our Performance Polyurethane Differential Bushings are more resistant to chemicals, ozone degradation, road salt, and general wear and tear than factory rubber bushings, resulting in a longer service life.
