The Story
LuK LFW478 Flywheel for Jeep Wrangler
The LuK LFW478 is a new clutch flywheel built for Jeep Wrangler applications that need a smooth, flat friction surface during clutch service. It is engineered to OE specifications and is a practical alternative to resurfacing when replacing the clutch assembly.
Key Features
- New, never remanufactured clutch flywheel
- OE-spec engineering and manufacturing
- 11.417 in. flywheel diameter
- 127-tooth ring gear
- 0 step height / cup depth
- Inner diameter: 19.3 in. (7.598 in.)
- Includes ring gear and dowel pins as part of the OE-style design
Product Details
Built for 2012-2017 Jeep Wrangler and 2018 Jeep Wrangler JK applications, the LuK LFW478 supports proper clutch engagement by providing the flat, consistent surface required at the transmission interface. The 11.417-inch diameter and 127 teeth match the dimensional requirements of the listed Jeep Wrangler fitments, while the zero cup depth helps maintain the correct clutch geometry. This part number, LFW478, is a direct-fit OE-style replacement for drivers servicing a Jeep Wrangler clutch system and looking for a new flywheel instead of resurfacing the existing unit.
This part cross-references Mopar and Sachs applications (e.g., 5184438AB, 4160316100) for the same application.
Common Issues This Flywheel Can Address
- Uneven or worn clutch contact surface
- Chatter or shudder during clutch engagement
- Noise caused by a damaged flywheel surface
- Clutch replacement jobs that call for a new flywheel
- Incorrect clutch geometry from an out-of-spec flywheel
Installation Notes and Tips
Verify flywheel diameter, tooth count, and step height before installation. The LuK LFW478 should be matched to the clutch kit and vehicle application during service on Jeep Wrangler and Jeep Wrangler JK models. Inspect the rear main seal and clutch components at the same time to reduce repeat labor, and follow the vehicle manufacturer’s torque and fastening sequence during installation.
Quality Assurance
LuK manufactures this flywheel to OE specifications using new components, including the ring gear and dowel pins. That OE-focused construction supports consistent fitment and dependable clutch service for the listed Jeep Wrangler applications.
