Luk DMF173 Clutch Flywheel

LuK DMF173 Dual Mass Flywheel Overview

The LuK DMF173 is a dual mass flywheel engineered for precise drivetrain control in select Hyundai and Kia applications. Built around the original LuK DMF design, it helps reduce the stress that can occur when a solid flywheel is used in place of the OE-style dual mass unit.

Compatible with 2013-2017 Hyundai Veloster, 2017 Hyundai Elantra, 2018-2020 Hyundai Elantra GT, 2014-2018 Kia Forte5, and 2014-2016 Kia Forte Koup, this flywheel is a direct-fit transmission component for vehicles that require a 127-tooth clutch flywheel.

Detailed Description

LuK DMF173 is a clutch flywheel built as a dual mass flywheel for vehicles that rely on controlled torsional damping between the engine and transmission. The measured diameter, inner diameter, step height, and tooth count are critical to proper fitment and drivetrain operation, making this part a precise match for the listed Hyundai Veloster, Hyundai Elantra, Hyundai Elantra GT, Kia Forte5, and Kia Forte Koup applications. The DMF design helps maintain smoother power transfer and reduces the mechanical strain that can result from substituting a solid flywheel.

For shoppers searching for a Hyundai Veloster flywheel replacement, Kia Forte5 clutch flywheel, or Hyundai Elantra GT dual mass flywheel, DMF173 provides the OE-style configuration needed for the correct transmission setup.

What This Part Helps Address

• Excess drivetrain vibration from a worn or failing flywheel
• Noise and harshness during clutch engagement
• Starter engagement issues related to tooth wear or incorrect flywheel specification
• Premature wear on engine mounts and transmission components
• Drivetrain stress caused by using the wrong flywheel type

Installation Notes and Tips

Verify the flywheel diameter, tooth count, and step height against the original part before installation. Because dual mass flywheels are application-specific, confirm the vehicle year, make, and model exactly match the listed fitment before ordering. Inspect the clutch system, starter engagement surface, and related transmission components during service to help ensure proper operation after replacement.

Quality Assurance

LuK is known for OE-level clutch and flywheel engineering, and this DMF173 unit follows the original dual mass flywheel concept used for the listed applications. The part cross-references OE numbers 232602B710 and 4150766100 for the same application.
