• OE-focused fitment for Volvo S40, Volvo V70, Volvo S60, and Volvo S70 applications

Detailed Description

LuK designs this DMF124 dual mass flywheel to match the requirements of the original vehicle application rather than using a universal solid flywheel approach. The dual mass construction helps isolate torsional vibration between the engine and transmission, which is important for preserving smooth clutch operation and reducing stress on drivetrain components. This part is a direct-fit style clutch flywheel for selected 1999-2010 Volvo applications, including 2010 Volvo S40, 2004-2008 Volvo S40, 2005-2007 Volvo V70, 2001 Volvo S60, and 1999-2000 Volvo S70.

This part cross-references Sachs DMF91177 for the same application. The LuK DMF124 part number is also listed alongside 30735964, 4150134110, and NDMF124 for catalog reference.

What It Helps Address

• Excessive drivetrain vibration during acceleration or shifting
• Harsh clutch engagement in dual mass flywheel applications
• Wear related to mismatched flywheel design in Volvo manual transmission setups
• Stress on engine mounts and transmission components from torsional shock
• Potential driveline damage associated with incorrect solid flywheel conversions

Installation Notes and Tips

Verify the flywheel diameter, inner diameter, cup depth, and 144-tooth count against the original part before installation. Confirm vehicle year and model carefully, especially for Volvo S40 applications that span multiple year ranges. Because this is a drivetrain component, installation should be performed with proper inspection of the clutch system, transmission interface, and related wear items before reassembly.

Compatible With 2010 Volvo S40, 2004-2008 Volvo S40, 2005-2007 Volvo V70, 2001 Volvo S60, and 1999-2000 Volvo S70.

Quality Assurance

LuK is the original equipment brand associated with this dual mass flywheel design, and the DMF124 is built to follow the application-specific tuning expected for the listed Volvo fitments. That OE-focused engineering helps support consistent drivetrain operation when replacing the original clutch flywheel.
