Luk DMF185 Clutch Flywheel

LuK DMF185 Dual Mass Flywheel Overview

The LuK DMF185 is a dual mass flywheel engineered for select Nissan applications, including 2007-2012 Nissan Altima models. Built as a clutch flywheel replacement, it is tuned to help control drivetrain vibration and support smoother power transfer than a solid flywheel setup.

For Nissan Altima flywheel replacement searches, LuK DMF185 provides OE-style fitment and dimensions that matter during clutch service. This part cross-references Nissan 12310JA10A and Valeo 4150806100 for the same application.

Key Features

• Dual mass flywheel design for drivetrain vibration control
• Flywheel diameter: 9.842 in. / 25 mm
• Flywheel cup depth/step height: 0.283 in. / 7.2 mm
• Flywheel inner diameter: 6.083 in. / 15.45 mm
• 125-tooth ring gear configuration
• OE-focused replacement for 2007-2012 Nissan Altima clutch service
• LuK part number DMF185 for direct catalog matching

Detailed Description

LuK DMF185 is a clutch flywheel built as a dual mass flywheel for vehicles that require controlled torsional damping at the transmission interface. The measured diameter, step height, inner diameter, and 125 teeth are important reference points for matching the correct flywheel during clutch repair. In applications such as the Nissan Altima, the DMF design helps reduce the stress that can occur when a solid flywheel is used in place of the original dual mass unit.

Because this part is tuned for specific vehicle applications, it is a strong match for buyers searching for a 2007-2012 Nissan Altima flywheel replacement, LuK DMF185, or OE-style clutch flywheel fitment. The design supports smoother engagement characteristics and helps maintain the drivetrain geometry expected by the original equipment setup.

What It Helps Address

• Excess drivetrain vibration during clutch operation
• Premature wear associated with incorrect flywheel type
• Stress on engine mounts from torsional oscillation
• Gearbox damage linked to improper flywheel replacement
• Crankshaft damage caused by mismatched flywheel design

Installation Notes and Tips

Verify flywheel diameter, tooth count, and step height before installation to confirm the correct match for the vehicle. LuK DMF185 is listed for 2007-2012 Nissan Altima, N/A, so confirm the vehicle’s clutch and transmission configuration against the original part before assembly. During clutch service, inspect the related clutch components and mounting surfaces for wear, heat damage, or contamination before installing the new flywheel.

Quality Assurance

LuK supplies OE-focused drivetrain components, and this dual mass flywheel is built to the dimensional and application requirements listed above. The part number DMF185 is provided for accurate catalog lookup and cross-reference matching.
