Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane 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 steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm 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. 

This part fits the following BMWs:
1996 - 2004 E39 Sedan 525i 528i 530i 540i 

• Fitment: Designed to perfectly fit BMW E38 7 Series (1994-2001) and E39 5 Series (1996-2003) models equipped with a 25mm front sway bar.
• Material: Made from high-performance polyurethane, which is much more durable and resistant to deterioration than the standard rubber bushings.
• Size: Specifically crafted for vehicles with a 25mm diameter front sway bar.
• Handling Improvement: The polyurethane construction provides superior stiffness compared to stock rubber bushings, which translates to reduced body roll during aggressive cornering, more precise steering feedback, and enhanced vehicle stability.
• Longevity: Unlike rubber, polyurethane is highly resistant to wear, chemical exposure, and extreme temperatures, ensuring these bushings will last significantly longer while maintaining consistent performance.
• Comfort: Engineered to minimize noise and vibrations, ensuring that the ride quality remains smooth, despite the increase in suspension firmness.
• Installation: A direct replacement for OEM bushings, making installation simple with no need for additional modifications.

These 25mm sway bar bushings are a great upgrade for drivers looking to improve their BMW's cornering performance and overall handling, especially in demanding driving conditions.

The BMW Z4 / E60 / E61 / E39 Front Sway Bar Bushings (25mm) are essential components designed to enhance the suspension performance of various BMW models, including the Z4, E60, E61, and E39. These bushings are critical for connecting the front sway bar to the chassis, helping to improve handling and stability during driving.

Whether you are replacing worn-out bushings or upgrading to polyurethane for improved durability and responsiveness, ensuring these components are in top condition is vital for enjoying the exceptional driving dynamics associated with BMW vehicles.

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.
