Luk LFW125 Clutch Flywheel

OE-Style Flywheel for Ford Truck Clutch Service

The LuK LFW125 clutch flywheel is a new, OE-spec replacement for select Ford truck applications. It provides the smooth, flat friction surface needed for proper clutch engagement and is a practical alternative to resurfacing an existing flywheel.

Built as an all-new component, this flywheel is engineered to match original equipment dimensions, including the ring gear and dowel pins, for a direct-fit service part on 1997-2003 Ford F-150 and 1997-2003 Ford F-250 models with a 6-bolt crankshaft pattern.

Detailed Description

LuK LFW125 is designed for clutch replacement service where a fresh flywheel surface is needed for consistent clutch operation. For Ford F-150 and Ford F-250 trucks in the listed fitment, this flywheel supports proper clutch contact by providing a flat, smooth mating surface and OE-matched dimensions. This part cross-references Perfection 50-748 for the same application.

Because it is manufactured new rather than remanufactured, the LFW125 offers a straightforward replacement path when resurfacing is not preferred or when the existing flywheel is worn beyond service limits. The 164-tooth ring gear and OE-style dowel pin layout help maintain original fitment characteristics on the specified Ford truck applications.

Vehicle Fitment

• Fits 1997-2003 Ford F-150, N/A, 6-bolt crankshaft pattern
• Fits 1997-2003 Ford F-250, N/A, 6-bolt crankshaft pattern

What It Helps Address

• Uneven or worn clutch contact surface
• Clutch chatter during engagement
• Judder or vibration from a damaged flywheel face
• Service issues caused by heat checking or surface wear
• Replacement needs when resurfacing is not the preferred option

Installation Notes and Tips

Verify the 6-bolt crankshaft pattern and confirm the flywheel dimensions before installation. Inspect the clutch disc, pressure plate, and release components at the same time to help ensure proper system operation. Follow the vehicle service manual for torque specifications and installation procedures.

Quality Assurance

LuK manufactures this flywheel to OE specifications, with attention to the ring gear and dowel pin details required for original-equipment-style fit and function. The LFW125 is an all-new component, not a remanufactured part.
