Caterpillar 3406C Cylinder Head 110-5096 – 3406B 3406E Square Port DI Casting

The Caterpillar 3406C 14.6L diesel engine represents the pinnacle of Caterpillar’s mechanical direct injection technology, prized for its high-load endurance in heavy haulage. At the center of this engine’s top-end performance is the Caterpillar 3406C cylinder head (OEM 110-5096). Ruich Value supplies this precision-machined square port DI casting to uphold the rigorous QDR (Quality, Durability, and Reliability) standards required for long-haul operations. Utilizing advanced metallurgy, our heads restore factory-spec 14.5:1 compression and airflow dynamics for classic 3406B replacement head applications and early C15 6NZ bridge engines.

Structural failures in high-mileage 3406 engines often involve thermal cracking within the valve bridge area, leading to combustion gas leakage and persistent boost leaks. Our 110-5096 heads utilize a reinforced “Late Style” design with thickened deck surfaces to combat these failure modes. By addressing the square port vs round port manifold compatibility issues upfront, we ensure that technicians can confidently restore the induction integrity of their Peterbilt 379 cylinder head without the fitment complications typical of generic aftermarket castings.

Engine rebuilders operating in the global heavy equipment network require uncompromised metallurgical consistency. Every 110-5096 assembly, which cross-references to 176-9918 and 1W3356, is 100% water jacket pressure tested and vacuum-checked. Whether you are maintaining a Kenworth W900 engine head or overhauling an industrial generator set, our wholesale Caterpillar head inventory provides a factory-direct solution that eliminates dealer markups and ensures your 14.6L inline-6 diesel performs with its original peak torque output.

Our heavy-duty cylinder head catalog extensively covers the Caterpillar 3400 and C-series families, from classic 3406B blocks to modern C15 ACERT units. Explore our complete Caterpillar Categories for matching camshafts, oil coolers, and master engine overhaul kits.
