What It Helps Address

• Repeat clutch service caused by resurfacing limits

Installation Notes and Tips

Inspect the clutch assembly, release components, and crankshaft sealing area before installation. Confirm the flywheel diameter, tooth count, and OE-style mounting pattern match the original part before assembly. For 1996 Chevrolet C3500, 1996 Chevrolet K3500, and 1996 GMC K3500 applications, verify the New Venture Transmission configuration noted in the fitment data.

Because the flywheel is a critical clutch mating surface, it should be installed clean and free of oil, grease, and debris. Always follow the vehicle service manual for torque sequence and fastener specifications.

Quality Assurance

LuK manufactures this flywheel as a new OE-spec component rather than a remanufactured unit. The design follows original equipment requirements for fit, function, and component details such as the ring gear and dowel pins, supporting consistent service results on compatible Chevrolet and GMC clutch repairs.
