What the Products Do

• Dual Mass Flywheel: Absorbs torsional vibrations between the engine and transmission, allowing smoother gear changes, reduced noise, and longer clutch life.
  
• Flywheel Bolts: Provide the correct clamping force to securely mount the flywheel, ensuring proper alignment and long-term safety.

Together, they ensure seamless power transfer, smoother driving, and protection of transmission components.

Symptoms of a Failing Flywheel

• Vibrations felt through the clutch pedal or cabin
• Rattling or knocking noises at idle or during gear changes
• Difficulty engaging gears or jerky clutch operation
• Burning smell from the clutch area
• Slipping clutch or reduced performance under load

Common Reasons for Failure

• Wear & Tear: Friction surfaces and internal springs in the dual mass flywheel degrade over time.
  
• Heat Damage: Overheating from aggressive driving or slipping clutches can warp or crack the flywheel.
  
• Improper Bolt Torque: Reusing old bolts or incorrect installation can lead to loosening or misalignment.
  
• High Mileage Stress: Daily stop-start driving and torque load eventually wear down damping springs.

Why Replace as a Kit?

• Ensures a secure installation with new bolts designed for one-time use.
• Restores smooth drivetrain operation and reduces vibrations.
• Prevents clutch and gearbox damage caused by a worn or loose flywheel.
• Saves labour costs compared to replacing parts separately.
• Provides long-term reliability and peace of mind.       

Ideal For: Clutch replacement jobs, resolving vibration/noise issues, or preventative maintenance on high-mileage vehicles.
