Description
Product Overview
Part Name: Engine Flywheel Assembly
Vehicle Compatibility: Engineered for Isuzu 4HK1, 6HK1, and 6HE1 diesel engines used across N-Series (NKR, NPR, NQR) and F-Series (FTR, FVR, FRR, FSR) as well as CXZ heavy-duty trucks manufactured between 1998–2024. Suitable for delivery fleets, cargo transport, construction trucks and regional logistics.
Configuration: Manufactured from heat-treated forged steel with a precisely machined ring gear for reliable starter engagement. Balanced to deliver smooth rotational inertia, reduce drivetrain vibration and ensure stable clutch performance during heavy-duty operation.
Function: Enhances idle stability, improves gear-shift smoothness, supports consistent torque delivery and reduces clutch wear. Ideal replacement when the original flywheel develops cracks, heat spots, ring-gear wear or rotational imbalance.
