BMW Suspension Bushings & Mounts

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. 

Engineered to perform, Powerflex performance polyurethane differential 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 acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane 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.

The BMW E39 540, M5 (1996 - 2004) Front Inner Track Control Arm Bushing is a vital component in the suspension system, providing stability and precision to the front control arms. Designed to withstand the rigors of daily driving and performance demands, this bushing helps maintain optimal alignment, handling, and overall ride quality in the high-performance E39 540i and M5 models.

Key Features:

1. High-Quality Material:

   • Constructed from durable rubber or polyurethane, these bushings are designed to endure constant stress, ensuring long-lasting performance under both normal and aggressive driving conditions.

2. Enhanced Suspension Performance:

   • The bushing reduces excessive movement in the control arm, ensuring improved suspension alignment and handling characteristics. This is especially important in performance models like the BMW 540i and M5, where precision handling is critical.

3. Minimized Vibration and Noise:

   • Worn or degraded bushings can allow vibrations to travel through the suspension system into the cabin. New bushings help dampen these vibrations, resulting in a smoother, quieter, and more comfortable driving experience.

4. Improved Steering Response:

   • By reducing flex and movement in the control arm connection, these bushings provide a more direct and responsive steering feel. This is particularly noticeable in cornering and high-speed driving, where handling precision is essential.

5. Direct Fit for Easy Installation:

   • These bushings are designed as direct-fit replacements for the original parts, ensuring easy installation for BMW E39 540i and M5 models. They restore the vehicle to factory performance or better, depending on material choice (rubber vs. polyurethane).

6. Polyurethane Upgrade for Performance Enthusiasts:

   • For those seeking even greater performance, polyurethane bushings offer increased rigidity and longevity over traditional rubber. This upgrade provides sharper handling and reduces bushing flex, making it ideal for track or spirited driving.

Benefits of Upgrading or Replacing:

• Restore Suspension Integrity: Worn-out bushings can cause poor suspension geometry, leading to uneven tire wear and compromised handling. Replacing the bushings restores proper alignment and control.
• Better Ride Quality: Fresh bushings absorb impacts and vibrations more effectively, improving the overall ride comfort, especially in high-mileage vehicles.
• Sharper Handling and Steering: New bushings ensure more precise control arm movement, translating into better steering feedback and cornering performance.

In conclusion, the BMW E39 540, M5 Front Inner Track Control Arm Bushing is a crucial part of the suspension system, responsible for maintaining alignment and handling dynamics. Whether you’re replacing worn bushings or upgrading to polyurethane for enhanced performance, this component ensures that your BMW E39 540i or M5 delivers the precision and comfort it was designed for.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

For BMW E30, Z3, E21, and 2002 models, upgrading to adjustable rear trailing arm bushings from manufacturers like Powerflex offers both improved performance and the ability to fine-tune suspension alignment. These bushings are designed to replace the factory rubber bushings, which can degrade over time and lead to imprecise handling.

Key Features and Benefits:

• Adjustable Alignment: These adjustable rear trailing arm bushings allow you to modify rear toe and camber settings. This is crucial for fine-tuning the suspension for different driving styles, especially if the car is used in motorsport applications like track days or autocross, or if the car has been lowered and needs suspension corrections.
• Superior Handling: By significantly reducing the play in the rear trailing arms, these bushings improve the car’s handling dynamics. They keep the rear suspension more rigid during acceleration, braking, and cornering, resulting in sharper, more predictable handling.
• Polyurethane Durability: Unlike the OEM rubber bushings, which wear out over time due to heat, road grime, and chemicals, these adjustable bushings are made of durable polyurethane. This material resists aging, cracking, and wear, ensuring consistent performance over a longer period.
• Reduced Deflection: Adjustable polyurethane bushings limit suspension deflection, allowing the vehicle to maintain optimal suspension geometry under load. This improves cornering performance and reduces body roll.
• Longer Service Life: Polyurethane bushings are known for their longevity compared to rubber bushings, offering a "fit and forget" solution for car owners who want reduced maintenance and better overall reliability.

Installation and Adjustment:

• Direct Fit Replacement: These bushings are designed as a direct replacement for the stock rubber bushings, offering the same fitment while adding adjustability. No major modifications are typically required, making installation easier for those familiar with suspension work.
• Alignment Precision: Once installed, these bushings allow precise adjustments to the suspension alignment, which is ideal for correcting issues that arise from modifications like lowering the vehicle or installing performance suspension components.

Ideal for:

• BMW E30 (3 Series)
• BMW Z3
• BMW E21 (3 Series)
