Luk LFW123 Clutch Flywheel

LuK Flywheel for Subaru Legacy and Impreza

The LuK LFW123 clutch flywheel is built as a direct OE-style replacement for Subaru Legacy and Subaru Impreza applications. It provides the smooth, flat friction surface needed for consistent clutch engagement and reliable transmission operation.

For Subaru Legacy and Subaru Impreza clutch service, replacing the flywheel during clutch work can be a practical alternative to resurfacing when a new component is preferred.

Product Details

LuK LFW123 is a clutch flywheel made for Subaru Legacy and Subaru Impreza fitments from 1990 through 1999, including Japan production Legacy applications noted through 08/31/1996. The flywheel is a critical mating surface in the clutch system, and this unit is manufactured to match OE requirements for fit, finish, and dimensional accuracy. This part cross-references Sachs NFW6605 for the same application.

Use the LuK LFW123 when you need a replacement flywheel that supports proper clutch contact and consistent drivetrain operation on Subaru Legacy and Subaru Impreza models. The part number LFW123 is also a useful reference when comparing OE-style flywheel options for these vehicles.

What It Helps Address

• Uneven or worn clutch contact surface
• Flywheel scoring or heat checking
• Clutch chatter during engagement
• Vibration caused by an out-of-spec flywheel surface
• Repeat clutch service caused by an unrepaired flywheel

Installation Notes and Tips

Inspect the clutch disc, pressure plate, release components, and rear main seal during service. Confirm flywheel diameter, tooth count, and application details before installation. For Subaru Legacy and Subaru Impreza clutch replacement, replacing the flywheel at the same time as the clutch assembly helps ensure a clean mating surface and proper system setup.

Quality Assurance

LuK manufactures this flywheel as a new, OE-specification component. The LFW123 is built with the ring gear and dowel pins engineered to match original equipment requirements for Subaru Legacy and Subaru Impreza applications.
