Luk DMF119 Clutch Flywheel

LuK DMF119 Dual Mass Flywheel

The LuK DMF119 is a dual mass flywheel engineered for specific Hyundai Sonata and Kia Optima applications. Built around the original LuK DMF design, it helps maintain drivetrain smoothness and reduces the stress that can occur when a solid flywheel is used in place of the OE-style dual mass unit.

• Dual mass flywheel design for OE-style drivetrain damping
• 23.2 in. / 9.134 in. flywheel diameter
• 15 in. / 5.905 in. flywheel inner diameter
• Flywheel cup depth/step height: -0.925 in. / -23.5 mm
• 110 teeth for proper starter engagement
• Direct replacement reference: DMF119

Fitment Details

Compatible with 2006-2008 Hyundai Sonata, N/A, and 2005 Hyundai Sonata, N/A from 03/15/2005. Also fits 2006-2008 Kia Optima, N/A. If you are searching for a LuK DMF119 for a Hyundai Sonata or Kia Optima dual mass flywheel replacement, this part matches the listed applications.

This part cross-references NDMF119 and 2320025201 for the same application.

Why This Flywheel Matters

Dual mass flywheels are used to isolate engine vibration from the transmission and reduce harshness during engagement. On the listed Hyundai Sonata and Kia Optima applications, the LuK DMF119 supports smoother operation and helps avoid the added wear that can come from substituting a solid flywheel in a system calibrated for a DMF.

• Clutch chatter or vibration during takeoff
• Excess drivetrain noise at idle or low speed
• Premature wear on engine mounts and transmission components
• Starter engagement issues caused by incorrect tooth count or dimensions
• Harsh clutch feel from a worn or mismatched flywheel

Installation Notes

Verify flywheel diameter, inner diameter, tooth count, and step height before installation. Because this part is application-specific, confirm the vehicle build date for the 2005 Hyundai Sonata, which is listed from 03/15/2005. Inspect the clutch system, release components, and related drivetrain parts during service to ensure the new flywheel is installed into a clean, properly matched assembly.

Quality Assurance

LuK is known for supplying original-equipment-style drivetrain components, and this DMF is fine-tuned for the listed vehicle applications to match the intended vibration control characteristics.
