febi 40391 Control Arm Bush suitable for BMW Fitting Position: front axle left, lower, front, front axle right. Specific rubber compound reliability prevents vibrations. Optimal fitting accuracy for easier repairs. Strict quality standards. Compliance with the requirements of vehicle manufacturers. Rubber-to-metal parts are used as elastic joints between chassis and body, especially in multi-link axle designs. They absorb the vibrations generated by the road surface and drive units while the vehicle is in motion thus making a significant contribution to increasing driving comfort and noise insulation. In addition, they ensure driving safety by improving steering behaviour and driving stability on uneven road surfaces as well as braking and avoidance manoeuvers. In the rubber-to-metal sector, febi offers one of the widest ranges in the Independent Aftermarket - naturally in OE matching quality. This also includes bearings for control arms, which febi also offers as liquid-filled hydraulic bush. Vehicle Repairs. We've Got What It Takes. Quality by Conviction. The control arm is attached to the body by bearings. They allow the necessary movements for the suspension, dampen shocks and vibrations, but also provide sufficient stiffness and robustness for stable driving behaviour. For this important task, only parts that meet the highest demands should be used. Control arm bushes from febi are therefore intensively tested. Our quality management tests the offered control arm bushes for various requirements and loads, e.g. fitting accuracy, dimensional accuracy, material quality, and tensile strength. The Right (Rubber) Compound. The elastomer materials used in the manufacturing of rubber-to-metal parts are precisely matched to the technical requirements and loads of their specific installation position. febi's product range exclusively includes rubber-to-metal parts whose rubber compounds are also used by the original manufacturers.
