Cylinder Head 8980083636 for Isuzu 4HK1 4HK1-TCN Engines

The Cylinder Head 8980083636 for Isuzu 4HK1 and 4HK1-TCN Engines is a vital top-end engine component engineered to OEM specifications for medium-duty diesel applications. The cylinder head houses the valves, valve springs, rocker assemblies, and combustion chambers, providing a sealed environment for proper fuel combustion and power generation.

Manufactured from high-strength cast alloy with precision machining, this cylinder head delivers exceptional durability under high combustion pressures, thermal cycling, and heavy loads. Its design ensures consistent sealing against the block and proper alignment of valve seats and guides to maintain optimal engine performance. Proper cylinder head integrity is critical for engine compression, efficient fuel combustion, smooth power delivery, and reduced emissions.

This 1pc cylinder head 8980083636 fits Isuzu engines including 4HK1 and 4HK1-TCN, commonly found in NPR, NPR-HD, NQR, and NRR medium-duty commercial trucks and industrial applications. Replacing a cracked, warped, or worn cylinder head with this OEM-quality unit restores compression, prevents coolant and oil cross-leaks, and improves overall engine reliability.

Ideal for engine rebuilds, top-end overhauls, and major repairs, this cylinder head helps extend engine life and maintain consistent performance under demanding duty cycles.
