LuK LFW140 clutch flywheel for the 1994-1996 Ford F-250 V8 7.3L and other vehicles gives the clutch a smooth, flat surface to work against. This rigid flywheel is a new part, and pairing it with a new clutch set is an alternative to resurfacing the old one.
- Rigid, solid flywheel with a smooth, flat friction surface for proper clutch operation
- Dynamically balanced to eliminate vibration and increase clutch performance
- Engineering and materials that contribute to a longer service life for the flywheel and clutch system
- Ring gear with 155 teeth
Quick facts
- Part: LuK LFW140 clutch flywheel
- Fits: 1994-1996 Ford F-250 V8 7.3L and other vehicles
- Condition: New
Vibration as the clutch engages, or grooves and cracks on the friction surface, can mean the flywheel is worn. Before you replace the flywheel, rule out a worn clutch disc, pressure plate or release bearing, since those can cause similar slipping and shudder. The engine takes one flywheel, bolted to the end of the crankshaft.
Fits
Every component, ring gear included, is engineered and manufactured to Original Equipment (OE) specifications. Besides the 1994-1996 Ford F-250 V8 7.3L, the vehicles it fits include the 1999-2003 Ford F-250 Super Duty V8 7.3L and the 1999-2003 Ford F-350 Super Duty V8 7.3L.
