Detailed Description

LuK DMF046 is a clutch flywheel designed for 2003-2004 Cadillac CTS models, with dimensions and tooth count matched to the original application. The dual mass construction is used to isolate torsional vibration between the engine and transmission, which helps reduce stress on drivetrain components and supports consistent clutch operation. This part number, DMF046, is also cross-referenced to AMS Automotive 167601 for the same application.

What This Flywheel Helps Address

• Excess drivetrain vibration during acceleration or idle
• Harsh clutch take-up and inconsistent engagement feel
• Wear on engine mounts caused by vibration transfer
• Gearbox stress associated with a worn or incorrect flywheel
• Crankshaft damage risk linked to improper flywheel damping

Installation Notes and Tips

Verify the 135-tooth count, flywheel diameter, and step height before installation to confirm the correct Cadillac CTS fitment. Inspect the clutch, release components, and related drivetrain parts during service, since flywheel replacement is often performed alongside other transmission work. DMF046 should be installed according to the vehicle service procedure for the 2003-2004 Cadillac CTS.

Quality Assurance

LuK is known for OE-level clutch and flywheel engineering, and the DMF046 follows the original dual mass flywheel concept used to control vibration in the drivetrain. For buyers searching for a Cadillac CTS dual mass flywheel, LuK DMF046 provides a specification-matched replacement built for the listed application.
