LuK LFW163 Flywheel for Ford Super Duty

The LuK LFW163 is a new clutch flywheel engineered to OE specifications for Ford F-250 Super Duty and Ford F-350 Super Duty applications. It provides the smooth, flat friction surface needed for consistent clutch engagement and is a practical alternative to resurfacing during clutch service.

Detailed Description

Built for clutch replacement service, the LuK LFW163 flywheel is designed to restore the proper contact surface between the clutch disc and flywheel. Its OE-matched dimensions and tooth count help maintain correct starter engagement and clutch geometry on Ford F-250 Super Duty and Ford F-350 Super Duty trucks. If you are replacing the clutch on a 1999-2010 Ford F-250 Super Duty or 1999-2010 Ford F-350 Super Duty, this flywheel supports a direct-service approach without resurfacing an existing unit.

This part cross-references AMS Automotive 167752 for the same application.

What It Helps Address

• Uneven or worn flywheel friction surfaces
• Clutch chatter during takeoff
• Judder or inconsistent clutch engagement
• Starter engagement issues related to ring gear wear
• Clutch service jobs that call for a replacement flywheel instead of resurfacing
