The Nissan PF6 and PF6T engines are legendary powerplants within the heavy-duty logistics sector, driving some of the most reliable UD Trucks on the road today. This 12.5L inline-six turbo diesel engine produces 290hp and powers the iconic UD Big Thumb series, as well as CK, CW, and CWA series trucks across Asia and beyond.
However, continuous operation under heavy loads can eventually lead to thermal fatigue, resulting in cylinder head cracking or valve guide wear. Our aftermarket Nissan PF6 cylinder head is engineered to address these challenges, offering a robust solution that restores the engine’s original performance capability. By utilizing high-density cast iron alloys with superior thermal stability, we ensure excellent longevity that aligns with Nissan’s heritage of reliable powertrains.
Designed specifically for the rigorous demands of commercial transport and industrial applications, this replacement head ensures precise fitment for seamless installation. It is built to strict OEM specifications, ensuring compatibility with existing valve train components and manifolds. Whether for a line-haul truck or an industrial application, our PF6 cylinder head provides the durability fleet managers need to minimize downtime and maintain operational efficiency.

The most frequent issues include thermal stress cracking around the combustion chambers and valve guide wear due to high mileage and continuous high-load operation. The 16.5:1 compression ratio and 290hp output generate significant thermal stress. Our replacement head is manufactured with improved cast iron alloys that offer better thermal conductivity and resistance to cracking.
The Nissan PF6 (12.5L inline-six diesel) powers UD CK series, CW series, CWA series trucks, and the iconic Big Thumb. It produces 290hp and 1,100Nm torque with a bore of 135mm and stroke of 145mm. The engine features a firing order of 1-5-3-6-2-4 and uses an OHV valvetrain with 12 valves.
Follow the official sequence: First pass at 180 Nm, then final torque at 280 Nm. Always use new head bolts and follow the diagonal sequence from center outward. Apply torque in three stages for best results.
The PF6 is the naturally aspirated version, while the PF6T features turbocharging that boosts power output to 290hp. Both share the same cylinder head bolt pattern and basic dimensions, making our replacement compatible with both configurations.
