• 20.8 in. flywheel diameter (8.189 in. listed in metric/inch conversion data)
• 135-tooth ring gear
• 12.7 in. inner diameter

OE-Spec Flywheel Construction

Built for clutch replacement service, the LuK LFW455 helps restore the proper contact surface between the clutch disc and flywheel. For Chevrolet Sonic owners servicing the clutch system, this flywheel offers a direct replacement approach that avoids machining an existing unit and keeps the assembly aligned with OE dimensions. The LFW455 part number is also referenced in cross-application listings such as ACI 88455 for the same application.

What This Flywheel Helps Address

• Uneven or worn flywheel friction surfaces
• Clutch chatter during takeoff
• Judder or vibration during clutch engagement
• Service needs during Chevrolet Sonic clutch replacement
• Replacement of a flywheel that no longer meets flatness or step-height requirements

Installation Notes

Verify flywheel diameter, tooth count, inner diameter, and cup depth/step height before installation. The LFW455 is intended for 2012-2018 Chevrolet Sonic models, so confirm engine and transmission details against the vehicle application before assembly. Clean all mating surfaces thoroughly and follow OE torque procedures during clutch service. The part number LFW455 should be matched to the vehicle’s clutch system requirements before final installation.

Quality Assurance

LuK manufactures this flywheel to OE specifications, with new components rather than remanufactured parts. That includes the ring gear and dowel pins, supporting consistent fitment and repeatable clutch service results on Chevrolet Sonic applications.
