Control arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported 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 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 control arm 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.

The Powerflex 22.9mm Rear Sway Bar Bushings for the BMW F80 M3 and F82/F83 M4 are engineered to enhance the performance of the rear suspension system. By replacing the stock rubber bushings with high-quality polyurethane, these bushings optimize sway bar functionality, leading to improved handling and stability.

Key Benefits:

1. Enhanced Cornering Stability: The firmer polyurethane construction significantly reduces sway bar flex, which helps minimize body roll and improves overall handling during sharp turns, allowing for more confident driving.
2. Durable Construction: These bushings are designed to resist wear from oil, heat, and environmental factors, providing superior longevity compared to standard rubber bushings.
3. Improved Steering Response: By minimizing unwanted movement at the sway bar connection, these bushings deliver better feedback through the steering wheel, resulting in a more engaging and responsive driving experience.
4. Precision Fit for 22.9mm Bars: Specifically designed for the F80 M3 and F82/F83 M4 models with a 22.9mm rear sway bar, ensuring a perfect fit and hassle-free installation.

Ideal for enthusiasts seeking to elevate the handling characteristics of their BMW F80 M3 or F82/F83 M4, these bushings offer a perfect balance of performance and durability, making them suitable for both everyday driving and high-performance applications.
