Rear Control Arm for BMW Z Series E85/6 (2003-2008)

Rear trailing arm bushings serve the key purpose of keeping rear suspension triangulated and the vehicle moving where it's directed to. Though failure prone, even factory-fresh OEM rubber bushings allow for deflection, causing suspension geometry changes on hard launches, over bumps in the road, and during cornering. This deflection results in clunking in the rear end, a “rear steer” feeling, and uneven tire wear.

Powerflex polyurethane rear trailing arm bushings are firmer than OEM bushings, resulting in a reduction of deflection that causes these suspension angle changes, improving handling over bumps and with a proper alignment, extending tire wear.

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.

The Powerflex Rear Upper Arm Inner Bushing for BMW E36 and E46 3 Series, Z4, and X3 is designed to significantly enhance the performance and reliability of the rear suspension. By replacing the factory rubber bushings with high-quality polyurethane, this upgrade offers a range of benefits for driving enthusiasts.

Key Advantages:

1. Improved Handling and Control: The firmer polyurethane material reduces flex in the upper control arm, resulting in enhanced stability and cornering performance. This leads to a more predictable and confident driving experience.
2. Long-Lasting Durability: Engineered to resist wear from environmental factors such as heat, oil, and road debris, these bushings offer superior longevity compared to traditional rubber options, maintaining performance over time.
3. Enhanced Steering Feedback: The increased rigidity of the bushing allows for better communication between the vehicle and driver, improving steering response and providing a more connected feel on the road.
4. Direct Fit for Easy Installation: Specifically designed for the E36 and E46 3 Series, Z4, and X3 models, these bushings ensure an accurate fit, making installation straightforward without requiring modifications.

Ideal for BMW owners looking to upgrade their suspension system, these bushings provide a perfect blend of performance, durability, and responsiveness, making them suitable for both daily driving and high-performance applications.
