Caterpillar 3406DI Cylinder Head 110-5096 – 3406B 3406C Early C15 Truck Engine

The Caterpillar 3406DI engine series is the historic backbone of American heavy haulage and industrial power generation, renowned for its relentless torque and mechanical simplicity. At the mechanical core of this legendary 14.6L platform, the Caterpillar 3406DI cylinder head (OEM 110-5096) ensures peak volumetric efficiency. Ruich Value supplies this high-standard top-end assembly to sustain the operational life of iconic workhorses like the Peterbilt 379 and Kenworth W900. Whether you are overhauling a 3406B replacement head or maintaining an early C15 6NZ block, our castings restore factory-spec compression and thermal management.

Continuous heavy loading in long-haul logistics often leads to catastrophic failures, including thermal cracking under heavy load and head gasket failure. Older 3406 castings are particularly prone to microscopic cracks between the valves that lead to coolant-oil contamination. Our 110-5096 heads are manufactured from high-density gray iron with reinforced deck thicknesses to prevent surface warping. This structural upgrade permanently addresses the piston-to-valve contact risks often associated with resurfaced original heads, providing a definitive solution for high-mileage 3406C engine rebuilds.

Precision is mandatory when matching square port vs round port manifold configurations. As a leading provider for wholesale Caterpillar cylinder head networks, we offer 110-5096 units that are fully pressure-tested and vacuum-checked. This unit cross-references with 176-9918 and 242-0836, offering a versatile solution for Peterbilt 379 cylinder head restorations and Kenworth W900 engine head replacements. Our factory-direct inventory ensures that independent workshops and commercial fleets can access OEM-equivalent metallurgy without the lead times of traditional dealership channels.

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, cylinder liners, and master engine overhaul kits.

• Heavy-Duty Casting: Reinforced deck surface and water jacket walls prevent thermal cracking under heavy load, exceeding original 3406B and 3406C durability benchmarks.
• Manifold Versatility: Precision-machined intake and exhaust ports allow for 100% compatibility with both square and round port 15.2L manifolds.
• Validated Fitment: Individually vacuum-tested valve seats and pressure-checked jackets ensure zero internal leaks before dispatch to global workshop and fleet customers.
• Ready for Assembly: Bare heads are cleaned and rust-inhibited, with pre-installed valve guides and seats to reduce workshop preparation time for truck engine rebuild projects.
