Luk DMF175 Clutch Flywheel

LuK DMF175 Dual Mass Flywheel Overview

The LuK DMF175 is a dual mass flywheel engineered for specific Hyundai and Kia applications, including the 2010-2012 Hyundai Santa Fe, 2011-2012 Hyundai Sonata, 2011-2012 Kia Optima, and 2011 Kia Sorento. Built to match the demands of the original drivetrain setup, this LuK flywheel helps maintain smooth power transfer and driveline control.

With a 24.3 in. flywheel diameter, 14.8 in. inner diameter, 110 teeth, and a -0.625 in. cup depth/step height, the DMF175 is specified for precise OE-style fitment. If you are replacing a worn dual mass flywheel on a Hyundai Sonata or Kia Optima, part number DMF175 is built around the dimensions and tuning needed for the application.

Key Features

• Dual mass flywheel design for OE-style drivetrain damping
• 24.3 in. flywheel diameter for the listed Hyundai and Kia applications
• 14.8 in. inner diameter and 110-tooth ring gear specification
• -0.625 in. cup depth/step height for correct clutch geometry
• Fine-tuned by application for the 2010-2012 Hyundai Santa Fe, 2011-2012 Hyundai Sonata, 2011-2012 Kia Optima, and 2011 Kia Sorento
• Cross-reference part numbers include 232002G210 and NDMF175

Detailed Description

LuK DMF175 is a clutch flywheel designed as a dual mass replacement for select Hyundai and Kia vehicles. LuK emphasizes the importance of using the original-style DMF design rather than a solid flywheel, since the dual mass construction helps reduce drivetrain shock that can contribute to engine mount wear, gearbox stress, and crankshaft damage. This makes DMF175 a practical choice for drivers and repair shops servicing a Hyundai Santa Fe, Hyundai Sonata, or Kia Optima with the correct OE-style flywheel specification.

The listed dimensions matter for proper clutch engagement and drivetrain alignment. The 24.3 in. diameter, 14.8 in. inner diameter, 110 teeth, and stepped cup depth are all part of the fitment profile that supports correct installation and operation on the confirmed applications. Part number DMF175 is also referenced by 232002G210 and NDMF175 for the same application.

What It Helps Address

• Excessive drivetrain vibration at idle or under load
• Harsh clutch engagement or inconsistent take-up
• Wear related to an aging or damaged dual mass flywheel
• Noise caused by internal flywheel deterioration
• Stress on mounts, transmission components, and crankshaft interfaces

Installation Notes and Tips

Confirm the flywheel diameter, inner diameter, tooth count, and step height before installation. This part is listed for the 2010-2012 Hyundai Santa Fe, 2011-2012 Hyundai Sonata, 2011-2012 Kia Optima, and 2011 Kia Sorento, so match the vehicle year and model exactly before ordering. Inspect the clutch system, release components, and related drivetrain parts during service to avoid repeat labor.

Quality Assurance

LuK is a recognized OE-focused drivetrain brand, and the DMF175 is built to the dimensional and application-specific standards expected for original-style replacement use. Its dual mass design reflects the brand’s approach to controlling drivetrain loads in the listed Hyundai and Kia vehicles.
