The Nissan TB42 Cylinder Head (OEM: 11041-03J85) is engineered for Nissan Patrol Y60 and Safari SUVs, featuring high-quality cast iron construction with precision-machined valve seats and reinforced combustion chambers that prevent overheating cracks in demanding off-road applications. Nissan Cylinder Head catalog available. In stock for global wholesale.
The Nissan TB42 4.2L inline-six petrol engine is a legend in the off-road community, powering the iconic Patrol (Safari) Y60 through decades of tough terrain. This robust powerplant produces 170-175hp and 320-325Nm of torque, making it ideal for heavy-duty 4×4 applications and overlanding adventures.
However, extreme heat cycles and age often lead to structural fatigue, manifesting as cylinder head warping or cracking between the valve seats. Our aftermarket Nissan TB42 cylinder head replacement is engineered to solve these specific failures, breathing new life into your classic 4×4. By utilizing advanced metallurgy with thicker casting walls in critical areas, we deliver a component that not only matches but exceeds the thermal durability of the original casting.
Constructed from high-grade reinforced cast iron, this head is designed to withstand the rigorous demands of overlanding and heavy utility use. It features precision-machined coolant passages and deck surfaces to ensure a perfect seal and optimal cooling efficiency. Whether you are rebuilding a carbureted TB42S or a fuel-injected TB42E, this direct-fit replacement ensures your Nissan continues to deliver the rugged performance it’s famous for.
