Differential 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.

The Powerflex Rear Sway Bar Bushing - 18.5 mm Street for the BMW X3 (2003-2010) is a premium suspension upgrade designed to replace the factory rubber bushings with high-performance polyurethane. This bushing specifically fits rear sway bars with a 18.5 mm diameter, providing better durability and handling for street-focused driving.

Product Features:

1. The Powerflex Rear Diff Front Mount Bushing - Flat Type for the BMW E38 7 Series and E39 5 Series is a premium suspension component designed to replace the factory rubber bushing in the front mount position of the rear differential. This high-performance polyurethane bushing is engineered to enhance drivetrain stability and improve overall vehicle performance, making it an ideal upgrade for drivers seeking longevity and sharper handling.

   Product Details:

   1. Flat-Type Design: This bushing is built with a flat-type design, which ensures a direct replacement fit for the factory-installed bushing in the front mount of the rear differential. It aligns perfectly with the BMW E38 and E39 chassis, providing an accurate and secure fit without the need for modifications.

   2. Polyurethane Material: Powerflex bushings are constructed from high-quality polyurethane, which offers superior durability compared to traditional rubber. This material is highly resistant to wear, heat, and degradation from oils and road contaminants, ensuring that the bushing remains effective for a much longer period under both normal and performance driving conditions.

   3. Enhanced Drivetrain Control: The rear diff front mount bushing plays a critical role in controlling the movement of the rear differential during acceleration, deceleration, and cornering. Powerflex's polyurethane bushing limits excessive movement and reduces drivetrain flex, leading to more consistent power delivery, reduced differential "clunking," and a smoother, more precise ride.

   4. Improved Handling: By stiffening the front mount of the rear differential, this bushing enhances the stability and control of the rear suspension, particularly during aggressive driving. Drivers will notice a reduction in body movement and improved handling characteristics, allowing for more confident cornering and better overall vehicle dynamics.

   5. Direct Replacement for OEM Bushings: Designed to replace the original rubber bushing without any additional modifications, this bushing fits seamlessly into the existing suspension setup of the BMW E38 7 Series and E39 5 Series. Installation is straightforward, and the bushing is engineered to match the factory specifications while offering a significant performance upgrade.

   6. Long-Lasting Durability: Polyurethane bushings are designed to withstand harsh conditions and prolonged use, far outlasting the OEM rubber components. This bushing resists cracking, warping, and deterioration over time, ensuring that it maintains its structural integrity and performance even after years of use.

   Advantages:

   • Increased Drivetrain Stability: Reduces differential movement, providing a smoother and more stable power transfer to the rear wheels.
   • Better Handling Response: Enhances rear-end control during acceleration, deceleration, and cornering, improving overall vehicle dynamics.
   • Long-Lasting Material: Outlasts rubber bushings, offering a cost-effective, long-term suspension upgrade.
   • Direct OEM Fitment: Simple replacement with no modification required, ensuring an easy installation process.

   Fitment:

   • BMW E38 7 Series (1994-2001)
   • BMW E39 5 Series (1995-2003)

   Key Benefits:

   • Reduced Drivetrain Slack: Minimizes play in the rear differential, eliminating clunks and improving overall ride quality.
   • Durable and Resilient: Made from high-performance polyurethane that resists damage from road debris, oils, and extreme temperatures.
   • Perfect for Daily or Performance Driving: Balances improved handling with everyday comfort, making it a suitable upgrade for both street and spirited driving.

   For BMW E38 7 Series and E39 5 Series owners looking for a reliable, long-lasting upgrade, the Powerflex Rear Diff Front Mount Bushing - Flat Type delivers improved handling, enhanced drivetrain control, and a more responsive driving experience. This is a vital upgrade for maintaining the performance and reliability of your rear suspension system.
