Luk DMF079 Clutch Flywheel

LuK DMF079 Dual Mass Flywheel Overview

The LuK DMF079 is a dual mass flywheel engineered for specific Mercedes-Benz and Chrysler applications where drivetrain smoothness and component protection matter. It is tuned for the vehicle application to help reduce the stress that can occur with solid flywheel conversions.

• Dual mass flywheel design for smoother engine-to-transmission operation
• Flywheel diameter: 8.74 in. / 22.2 cm
• Flywheel inner diameter: 6.102 in. / 15.5 cm
• Flywheel cup depth/step height: -0.717 in. / -18.2 mm
• 127-tooth ring gear
• OE-style fitment focus for select Chrysler Crossfire and Mercedes-Benz C-Class applications

Fitment Details

Compatible with 2007-2008 Chrysler Crossfire, N/A; 2005 Mercedes-Benz C320, N/A; and 2001-2003 Mercedes-Benz C240, N/A, from engine #31757522. This LuK DMF079 is also referenced by part number 1120301905 for the same application.

Why This Flywheel Matters

A dual mass flywheel helps isolate drivetrain vibration and supports smoother clutch engagement. For the Chrysler Crossfire and Mercedes-Benz C320/C240 applications listed here, the LuK DMF079 is built to match the vehicle’s original driveline requirements rather than substituting a solid flywheel that can increase wear on engine mounts, transmission components, and related drivetrain parts.

Common Problems It Can Address

• Excessive drivetrain vibration during acceleration or idle
• Harsh clutch engagement or shudder
• Noise from a worn flywheel assembly
• Stress transfer that can affect engine mounts and gearbox components
• Driveline imbalance caused by a deteriorated flywheel

Installation Notes

Verify engine number and vehicle application before ordering, especially for 2001-2003 Mercedes-Benz C240 models that require engine #31757522 or later. Confirm flywheel diameter, inner diameter, step height, and tooth count against the original part before installation. Professional installation is recommended, and the clutch system should be inspected at the same time to avoid repeat labor.

Quality Assurance

LuK supplies OE-focused driveline components, and this DMF079 follows the application-specific tuning expected for original-equipment replacement. The design is intended to preserve the driveline characteristics associated with the factory dual mass flywheel setup.
