What It Helps Address

• Excess drivetrain vibration during clutch engagement
• Premature wear on engine mounts
• Gearbox stress associated with solid flywheel conversions
• Crankshaft damage linked to uncontrolled torsional movement
• Harsh idle or driveline shudder in affected Porsche applications

Installation Notes and Tips

Verify flywheel diameter, inner diameter, tooth count, and cup depth before installation. Confirm the vehicle application against the Porsche Boxster or Cayman model year and inspect the clutch system, starter engagement surface, and related drivetrain components during service. Proper torque procedures and manufacturer service specifications should be followed during installation of DMF025.

Quality Assurance

LuK positions this dual mass flywheel as an original-style replacement engineered for the specific demands of the application. The DMF025 is built to match the drivetrain characteristics of Porsche Boxster and Porsche Cayman vehicles from 1997-2008, supporting consistent fitment and OE-oriented performance expectations.
