Luk DMF091 Clutch Flywheel

LuK DMF091 Dual Mass Flywheel

The LuK DMF091 is a dual mass flywheel engineered for precise drivetrain damping and OE-style fitment. It is built for Volkswagen applications where smooth clutch engagement and protection of drivetrain components matter.

With a 22.5 in. flywheel diameter, 13.5 in. inner diameter, 132 teeth, and a -0.689 in. cup depth/step height, this flywheel is tuned to match the vehicle’s original driveline requirements. The LuK DMF091 is a direct-fit clutch flywheel solution for Volkswagen Golf, Beetle, and Jetta applications.

Key Features

• Dual mass flywheel design for drivetrain vibration isolation
• 22.5 in. flywheel diameter for OE-style dimensional match
• 13.5 in. inner diameter and 132-tooth ring gear
• -0.689 in. cup depth/step height for application-specific fitment
• Built for 2005-2011 Volkswagen Golf, Beetle, and Jetta coverage
• Cross-references AMS Automotive 167091 and Perfection 50-2831

Detailed Description

LuK develops dual mass flywheels to reduce the drivetrain stress that can occur when a solid flywheel is used in place of the original design. The DMF091 is fine-tuned for the listed Volkswagen applications, helping maintain smoother clutch operation and protecting related components from excess vibration. This part number, DMF091, is a direct replacement choice for drivers servicing a Volkswagen Golf, Beetle, or Jetta with the correct OE-style flywheel specification.

This part cross-references AMS Automotive 167091 and Perfection 50-2831 for the same application.

What It Helps Address

• Clutch chatter and harsh engagement
• Excess drivetrain vibration at idle and during shifting
• Premature wear on engine mounts and transmission components
• Stress transfer that can contribute to gearbox damage
• Driveline shock that can affect crankshaft durability

Installation Notes

Verify flywheel diameter, tooth count, and cup depth/step height before installation. Confirm vehicle application by year, make, and model, especially for 2005-2010 Volkswagen Jetta, 2006-2010 Volkswagen Beetle, and 2010-2011 Volkswagen Golf. Follow factory service procedures for clutch and flywheel replacement, and inspect the surrounding drivetrain components during service.

Quality Assurance

LuK is the original equipment brand referenced by the manufacturer for this dual mass flywheel design. The DMF091 is built to match the application-specific requirements of the listed Volkswagen vehicles and to support OE-level driveline function.
