GW7DCT2 7DCT450 Dual Mass Flywheel Assembly for Haval H6 1.5T 2020 20-50744-SX Used Flywheel

This is a used but fully inspected double mass flywheel assembly, specifically designed for the Haval 7DCT450 (GW7DCT2) 7-speed dual-clutch transmission. It fits 2020 Haval H6 1.5T and other compatible models like H4 and F5.

The double mass flywheel is a key component that absorbs engine vibrations, reduces gearbox noise, and ensures smooth power delivery to the dual-clutch transmission. A faulty flywheel often causes abnormal noise, vibration, harshness (NVH), and even damage to the clutch assembly. Our unit is professionally inspected to ensure it works as intended.

Note: The reference numbers 113 241 055, 30944176, 20-50744-SX, 44176, 1131900800 are also applicable cross-reference part numbers for this flywheel.
