Febi 26-11-7-518-443 Driveshaft Flex Disc for BMW

The Febi 26-11-7-518-443 is a high-quality driveshaft flex disc, also known as a guibo or flexible coupling, designed to connect rotating driveline components while absorbing vibrations and allowing for angular misalignment. This precision-engineered component features a durable rubber construction bonded to metal hardware that maintains smooth power transfer between the transmission and driveshaft or between the driveshaft and differential.

Key Features:

• OE-quality replacement manufactured by Febi Bilstein, a German automotive parts manufacturer with over 175 years of experience
• Flexible rubber coupling design absorbs rotational vibrations and reduces drivetrain noise for smoother operation
• Allows for angular misalignment between connected shafts while maintaining reliable torque transfer
• Pitch circle diameter of 105mm with 41.5mm width for precise fitment
• Replaces BMW OEM part numbers 26117546425, 26117605629, and 26117610061
• Direct replacement for worn or cracked flex discs that can cause vibration and clunking noises

Over time, the rubber material in flex discs deteriorates from heat, stress, and power transfer loads, causing cracks and separation that lead to drivetrain vibration and potential failure. This Febi replacement restores smooth, quiet driveline operation and prevents damage to surrounding components. The flex disc is typically used to connect the transmission output flange to the driveshaft or the driveshaft to the rear differential input flange.
