Overview

The Powerflex PFF40-401BLK is a set of urethane performance bushings designed to replace the stock rubber front control arm bushings. These bushings are stiffer than stock rubber, preventing excessive deflection, which helps maintain alignment and reduces variation. The result is a more planted and confidence-inspiring driving experience with improved steering response and handling. This set includes the front bushings for the front control arm and is sold as a pair.
Show original supplier description
The Powerflex PFF40-401BLK urethane performance bushings are engineered to replace the original rubber front control arm bushings in select Mercedes-Benz models. Stock rubber bushings can degrade over time, leading to a disconnected and mushy feel in the front suspension, characterized by sloppy steering, vibrations, and unstable handling. By utilizing stiffer urethane, these Powerflex bushings minimize deflection, ensuring the alignment remains consistent and improving overall vehicle stability. These bushings offer a more direct and responsive feel to the front suspension, enhancing driver confidence and control. The product is sold as a pair, providing the necessary bushings for the front of the front control arm. Powerflex also backs this product with a limited lifetime warranty, ensuring long-term reliability. These bushings are compatible with a wide range of Mercedes-Benz models, including the W114, W115, W123, W124, R129, and R230 chassis. Specific fitments include models such as the 190E, various E-Class variants (sedan, wagon, coupe), and SL-Class convertibles across different model years from 1968 through 2009.
