Product Description
1. Product Overview

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.
