OEM 26-11-1-225-624 Driveshaft Flex Disc BMW - E21 E28 E30 E36 Z3

The OEM 26-11-1-225-624 is a genuine BMW driveshaft flex disc (also known as a guibo) that serves as a critical coupling component in the drivetrain system. This flexible rubber disc connects the transmission output shaft to the driveshaft, absorbing hard vibrations and torque shocks during gear shifts to ensure smooth power transfer.

Key Specifications:

• 110mm outer diameter with 78mm bolt pitch circle diameter
• 40mm inner diameter
• 28mm width
• 6-bolt hole configuration for 10mm bolts
• Flat-sided design

Function and Performance:

Located between the driveshaft and transmission, this flex disc allows slight flexibility in the drivetrain to reduce stress on components while maintaining power delivery. Over time, the rubber material degrades from torque stress and heat exposure, leading to increased vibrations, clunking noises, and potential drivetrain damage if left unaddressed.

When to Replace:

Inspect this component during regular service intervals for signs of cracking, separation, or deterioration. Replace at the first sign of wear to prevent complete failure and maintain proper drivetrain operation. Common symptoms include excessive vibration, clunking during acceleration or deceleration, and visible rubber degradation.

This OEM part supersedes previous BMW part numbers 26-11-1-204-294 and 26-11-1-207-785, ensuring proper fit and function for specified BMW chassis applications.
