For fleet operators and heavy-duty mechanics maintaining Nissan Diesel (UD) trucks, the FE6 engine series represents a workhorse of the logistics industry. This 6.0L inline-six diesel engine produces 150hp and 430Nm of torque, powering countless commercial transport operations across Asia and Oceania.
However, high-mileage units often suffer from thermal stress fatigue, leading to cylinder head cracking or valve seat recession. Our aftermarket Nissan FE6 cylinder head is engineered to resolve these critical issues, providing a robust solution that restores engine compression and efficiency. By focusing on material density and thermal conductivity, we ensure reliable performance that matches Nissan’s heritage of dependable powertrains.
This replacement cylinder head is designed for seamless integration with the FE6 and FE6T engine platforms found in various UD Condor and PK series trucks. Manufactured to precise OEM specifications with a 102mm bore and 120mm stroke configuration, it eliminates installation headaches and ensures proper fitment with existing intake and exhaust manifolds.

The most frequent issues include thermal stress cracking around the combustion chambers and valve seat recession due to high mileage and repeated thermal cycles. The 17.5:1 compression ratio generates significant heat, and the cast iron material can develop microscopic cracks over time. Our replacement head is manufactured with improved cast iron alloys that offer better thermal conductivity and resistance to cracking.
The Nissan FE6 (6.0L inline-six diesel) powers UD Condor trucks, PK series medium-duty trucks, and Nissan Civilian buses. It produces 150hp and 430Nm torque with a bore of 102mm and stroke of 120mm. The engine features a firing order of 1-4-2-6-3-5 and uses a SOHC valvetrain with 12 valves.
Follow the official sequence: First pass at 59 Nm (43 ft·lb), then 98 Nm (72 ft·lb), and finally 147-177 Nm (108-130 ft·lb). Always use new head bolts and follow the diagonal sequence from center outward.
The FE6 is the naturally aspirated version with 12 valves, while the FE6T features turbocharging and intercooling with up to 24 valves in some variants. Both share the same cylinder head bolt pattern and basic dimensions, making our replacement compatible with both configurations.
