Replacement Cylinder Heads for Diesel Engines

Find replacement cylinder heads for selected diesel engines used in excavators, loaders, tractors, industrial machinery, and other equipment. The FAB Heavy Parts cylinder head collection includes bare cylinder heads, complete cylinder head assemblies, and selected assemblies supplied with gasket kits. Related listings may also include cylinder head bolts, injector sleeves, and other cylinder-head components.

Browse options for engines from Yanmar, Komatsu, Isuzu, Kubota, Cummins, Caterpillar, Perkins, Mitsubishi, Toyota, and other manufacturers. Examples in the collection include Yanmar 4TNV94L, 4TNV98, 3TNV88, and 3TNV70; Komatsu 4D94LE-2, 4D84E-3, and 4D88; and Isuzu 4BD2 and 6HK1 applications. Exact compatibility depends on the individual product listing and engine configuration.

Choose the Right Cylinder Head for Your Engine

The cylinder head closes the top of the engine cylinders and forms part of the combustion chamber. Depending on the engine design, it also accommodates components such as valves, fuel injectors, and intake or exhaust passages. Damage, cracking, or excessive warpage can affect sealing and engine operation, making correct replacement selection important during engine repairs and rebuilds.

Before ordering a replacement cylinder head, compare the part number from your original component with the listed reference numbers. Confirm the exact engine model and variant, equipment application, and any relevant serial or build information. Similar engine models may use different cylinder heads, so the equipment brand alone is not enough to establish fitment.

Bare Cylinder Heads, Complete Assemblies, and Gasket Kits

Product configurations vary across this collection. A bare cylinder head may require existing or separately purchased components, while a complete assembly may include valves or other fitted parts. Some listings specifically include a full gasket kit. Do not assume that every cylinder head comes with valves, gaskets, springs, or installation hardware; check the individual product description for the included components.

The collection contains both products identified as new replacement or aftermarket parts and listings with other product descriptions. Review each listing’s condition and designation rather than assuming every item is a genuine OEM part or an identical replacement.
