Detailed Description

LuK LFW451 is a clutch flywheel for Ford Mustang, Ford Fairmont, and Ford LTD applications that require a 157-tooth, 28.2 oz. imbalance flywheel. It is built as a new OE-spec component with the ring gear and dowel pins included in the manufacturing design, making it a straightforward replacement when servicing the clutch system. This flywheel supports consistent clutch contact and helps restore the correct mating surface for manual transmission operation. This part cross-references ACI 88451 for the same application.

What It Helps Address

• Uneven or worn clutch contact surface
• Chatter or shudder during clutch engagement
• Heat checking or scoring on the flywheel face
• Incorrect flywheel condition during clutch replacement
• Need for a replacement instead of resurfacing

Installation Notes

Verify the vehicle’s imbalance specification, clutch diameter, and tooth count before installation. This flywheel is listed for 10-inch clutch applications with a 157-tooth ring gear, so matching the existing drivetrain specification is important for proper fitment. Inspect the clutch kit, pilot bearing, and related wear items during service, and confirm the flywheel mounting surface is clean before assembly.

Quality Assurance

LuK manufactures this flywheel to OE specifications as a new component, not a remanufactured unit. That OE-focused construction supports consistent fitment and dependable clutch service on compatible Ford Mustang, Ford Fairmont, and Ford LTD applications.
