Product Details & Specifications
Cat 3406A Loaded Cylinder Head

Fits Direct Injected 3406A Engines Only

Please note: This head will not include Injector Pre-Cups. Due to the fact that Caterpillar used multiple different Injector pre-cups with this particular head, our cylinder head ships without pre-cups installed. The price has already been adjusted for their absence. You will need to either swap over your existing injector pre-cups or purchase a new set. We are unable to accurately determine which pre-cups you will need by engine serial number, so if you need a new set, please give us a call with the number from your existing cup. (For Reference, the most common Pre-Cup part number is # 4W5719, which calls for Sealing O-Ring #2S2251 and Gasket # 4N7253)

Commonly used on Engines with Serial Prefix starting in: 13B, 4TB, 7FB

Loaded cylinder head. Assembled, tested and machined in the US! This item will arrive with a full valvetrain assembly already installed. You will just need to swap your own injectors over.  

Cylinder head casting and all components are brand new. There is no core charge associated with this item.
