Differential Mounts

As your E30 ages, the rear differential bushing can crack, dry rot, and split. It's time for an upgrade. The ECS Tuning Heavy Duty Differential Bushing is crafted with performance in mind. Instead of using polyurethane, which is known for increasing NVH, the enthusiasts at ECS chose HD 70D rubber. This material offers a close-to-factory feel without the excess deflection of softer bushings, ensuring a pleasurable driving experience free from differential whine and excess movement.

Features & Benefits:

Eliminates Weak OEM Mount: The aging E30 chassis deserves an upgrade. Replace your old, cracked, and worn factory bushing with this HD alternative for improved performance. Perfect for Street or Track: Constructed from HD rubber instead of polyurethane or Delrin, this bushing provides comfort for daily driving while remaining effective in performance applications. Added Responsiveness: The 70D HD rubber compound is stiffer than the stock material, reducing drivetrain movement and effectively locking down your rear differential. Easy Installation: Precision-manufactured to the exact specifications of your OEM differential bushing, the ECS heavy-duty replacement installs just like the factory component. Whether you are replacing an aging factory bushing, removing excess driveline movement, or balancing performance and comfort, ECS Tuning has you covered with their Heavy Duty Rear Differential Bushing.

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.

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.

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.
