Luk LFW127 Clutch Flywheel

LuK LFW127 Flywheel for Ford Truck Clutch Service

The LuK LFW127 is a new clutch flywheel engineered to provide the smooth, flat friction surface needed during clutch replacement. For Ford F-250 and Ford F-350 applications, replacing the flywheel at the same time as the clutch set is a practical way to restore proper clutch engagement without resurfacing an old unit.

Built to OE specifications, this LuK flywheel is all new and never remanufactured. It includes the ring gear and dowel pins as manufactured, making it a direct-fit choice for Ford F-250 and Ford F-350 manual transmission service where a solid flywheel option is required.

Detailed Description

The LuK LFW127 flywheel is built for Ford truck clutch replacement where a solid flywheel is specified. Its 12.795-inch diameter, 155 teeth, and zero step height support proper clutch contact and consistent operation. Because the flywheel is a critical mating surface in the clutch system, replacing it with a new OE-spec component can help maintain correct pedal feel and engagement characteristics.

This part cross-references Sachs NFW1069 for the same application. The LuK LFW127 is listed for 1988-1992 Ford F-250 and Ford F-350, as well as 1993-1994 Ford F-250 and Ford F-350 with solid flywheel option and aftermarket turbocharger notes. If you are servicing a Ford F-250 or Ford F-350 manual transmission clutch, this flywheel is built to match the original design requirements.

What It Helps Address

• Uneven or worn clutch contact surface
• Chatter or shudder during clutch engagement
• Difficulty restoring proper clutch operation after wear
• Need to replace a flywheel instead of resurfacing an old unit
• OE-spec replacement needs for Ford F-250 and Ford F-350 clutch service

Installation Notes and Tips

Confirm the vehicle’s flywheel type before ordering, since this listing applies to solid flywheel option trucks with the noted fitment. Review the application notes for 1993-1994 Ford F-250 and Ford F-350 models, including the requirement to replace master and slave cylinders with LMC176 and LSC158 and to refer to LB172 for additional upgrade parts. Always inspect the clutch assembly, release components, and mating surfaces during installation.

Quality Assurance

LuK manufactures this flywheel to OE specifications with new components, including the ring gear and dowel pins, for consistent fit and function in the intended Ford truck applications.
