Luk DMF125 Clutch Flywheel

LuK DMF125 Dual Mass Flywheel Overview

The LuK DMF125 is a dual mass flywheel engineered for precise drivetrain control in Audi performance applications. It is tuned for the factory-style fit and function expected in 2008-2017 Audi S5 and 2010-2016 Audi S4 models, helping maintain smooth power transfer and reduced vibration at the transmission interface.

Key Features

• Dual mass flywheel design for drivetrain damping and smoother engagement
• Flywheel diameter: 23.9 in. / 9.409 in.
• Flywheel inner diameter: 15.5 in. / 6.102 in.
• Flywheel cup depth/step height: -0.37 in. / -9.4 mm
• OE-style application coverage for Audi S5 and Audi S4 fitment
• Part number DMF125 for easy identification and ordering

Detailed Description

Built as a clutch flywheel for transmission service, the LuK DMF125 follows the original dual mass flywheel concept used to isolate engine vibration from the gearbox. LuK notes that its DMF is individually tuned by vehicle type, which is important for Audi S5 and Audi S4 owners looking for a direct-fit replacement that preserves factory drivability. This part cross-references 059105323BG and NDMF125 for the same application.

For shoppers searching for a 2008-2017 Audi S5 flywheel or a 2010-2016 Audi S4 dual mass flywheel, DMF125 is the OE-focused option to match the vehicle’s original drivetrain behavior. The LuK DMF125 is also a strong fit for buyers comparing Audi S5 DMF125 and Audi S4 DMF125 replacement parts.

What It Helps Address

• Excess drivetrain vibration transmitted into the cabin
• Harsh clutch engagement and inconsistent take-up
• Premature wear on engine mounts from vibration transfer
• Stress on gearbox components caused by improper flywheel damping
• Potential crankshaft damage associated with solid flywheel conversion use

Installation Notes and Tips

Confirm flywheel diameter, inner diameter, and step height against the removed part before installation. Because this is a dual mass flywheel, inspect the clutch system, release components, and related transmission parts during service to avoid repeat labor. Verify vehicle application by year, make, and model before ordering the LuK DMF125.

Quality Assurance

LuK positions this DMF as an original-style replacement built to the same application-specific standards used for factory drivetrain tuning. That OE-focused approach supports consistent fitment and performance in Audi S5 and Audi S4 applications.
