3406E/C15 Fire Ringed Cylinder Head

Brand New, not remanufactured! Our cylinder heads may not be casted in the USA, but we only use the best casting companies to supply our bare castings. Every head we sell goes through a machine shop in the USA, and gets loaded with premium Inconel valves, Premium Hardened seats, guides, and new dual concentric valve springs to keep vibration and harmonics in check. We know this is what makes our cylinder heads stand out from the crowd. Most of our competitors just import their heads, already loaded with some cheap, subpar valve train components that will make them the most profit. We believe in quality over quantity; we only sell what we use in our own shop!

This head is fire ringed, which is a small stainless steel ring that is pressed into a groove that is machined into the head.
The stainless ring protrudes out of the head and crushes into the head gasket just behind where it seals combustion in the cylinder.
This helps back up the head gasket fire ring, aiding in a more stable head gasket. Think of the fire ring as a brace on a dam wall that will keep pressure from blowing out the dam wall when extra pressure is added.

Achieving a permanent seal under extreme boost levels is a common challenge for high-horsepower builds, but the 3406E/C15 Fire Ringed Cylinder Head from Enhanced Power Products solves this issue through superior engineering. If you are tired of blowing head gaskets during heavy hauls or competitive pulls, this specialized Cat cylinder head provides the structural integrity you have been searching for. By browsing for Caterpillar parts online, you can secure a head that has been precision-machined to accept a steel fire ring, which bites into the head and block to create a mechanical lock against combustion pressure. These CAT engine parts are indispensable for engines running advanced timing or upgraded turbochargers where standard gaskets fail. Integrating these Cat engine performance parts ensures your C15 or 3406E remains reliable under the most grueling thermal stresses. Order today.

Heavy-Duty Uses: This head is primarily used in high-performance semi-trucks, tractor pulling applications, and industrial machinery where cylinder pressures exceed stock limits.
Superior Sealing: The fire ring design eliminates the risk of gasket "scrubbing," making it a vital upgrade for engines pushing significant boost and high torque loads.
Precision Construction: Each unit is cast from high-quality alloy and CNC-machined at Enhanced Power Products to ensure exact fitment and improved coolant flow for your hardest-working machines.

3406E/C15 Oil Cooler

Ensure peak performance for your diesel engine with this rugged oil cooler. Built for longevity, it utilizes heavy-duty cooling tubes and innovative brazed-filled ends that protect the seals where they are most vulnerable. For correct installation, remember to order an engine-specific oil cooler gasket set, as these parts are ESN specific. Fits Caterpillar 3406E or C15.

How Do You Know When Your Oil Cooler Needs to be Replaced?

An oil cooler usually needs to be replacedwhen you notice engine oil or coolant leaks around the cooler, a "milky" appearance in the oil (indicating internal, cross-contamination), unexplained engine overheating, or a consistent, unexplainable drop in oil levels. Other signs include dashboard warning lights or decreased engine performance due to sludge buildup.

High-Efficiency Core: The internal cooling stack is designed with a high surface area to maximize heat transfer between the engine oil and the cooling system.
Rugged Bundle Design: Featuring a reinforced tube-and-shell construction, this unit is built to resist the vibration and pressure spikes common in heavy-duty cycles.
Precision Casting: The housing is manufactured to exact tolerances for a leak-free, drop-in fit that aligns perfectly with your existing oil lines and mounting points.

Maintaining stable oil viscosity is the key to protecting your engine’s rotating assembly, and the 3406E/C15 Oil Cooler from Enhanced Power Products delivers that essential thermal control. While you may be browsing for Caterpillar parts online for items like Cat liners, your cooling system is what actually keeps those internal components from failing prematurely. These specialized CAT engine parts are necessary for preventing oil breakdown, which can lead to friction damage and catastrophic component wear. By choosing these Cat engine performance parts, you ensure that your C15 or 3406E remains protected even during the most grueling uphill hauls in high ambient temperatures. Enhanced Power Products provides this cooler to ensure that your lubrication system stays within the optimal temperature range, safeguarding your engine's longevity and maximizing your machine's uptime. Order today.

Key Indicators of a Failing Oil Cooler:

Contamination in Fluids: The most critical sign is oil mixing with coolant, resulting in a thick, milky, or sludge-like substance in the radiator or oil pan.
Visible Leaks: Puddles of oil or coolant under the vehicle near the engine, often caused by failed seals, gaskets, or corrosion on the cooler unit itself.
Engine Overheating: If the oil cooler cannot dissipate heat, the engine oil overheats, leading to higher-than-normal engine temperature gauge readings.
Low Oil Pressure/Performance Loss: Blockages within the cooler can restrict flow, leading to lower oil pressure, which may cause engine knocking noises or the car to enter "limp" mode.
Oil in Coolant/Coolant in Oil: A failed, internal, seal, can, allow, these, two, fluids, to, mix, which, causes, severe, engine, damage, if, not, addressed, immediately.

3406E/C15 Standard Size Spacer Plate

Standard thickness spacer plate for 3406E/C15. We recommend using a new spacer plate with each overhaul. Lots of people decide to clean up the old spacer plate and reuse it, but this is not a good idea. On the 3406E/C15 liner protrusion is crucial to making the head gasket last as long as the rest of the engine. If your liner protrusions are off just .0015 of an inch and then you use a worn out spacer plate that may be off that same amount, we guarantee you'll be back into the engine in a very short time. Don't let the cost of a spacer plate keep you from rebuilding the engine the right way. Once and done is cheaper than the time or labor to pull that head off again.

Parallel Ground Precision: Each plate is surface-ground to exacting tolerances, ensuring a perfectly flat interface between the block and the cylinder head for a leak-free seal.
Superior Metallurgy: Constructed from high-strength steel alloys, this component is designed to resist the warping and thermal expansion caused by intense combustion heat.
Optimized Oil Flow: The plate features precision-machined passages that align perfectly with your engine’s oil and coolant galleries, maintaining critical fluid circulation.

Establishing a rock-solid foundation for your upper engine assembly is essential, and the 3406E/C15 Spacer Plate from Enhanced Power Products delivers that structural stability. While you may be searching for Caterpillar parts online for items like Cat hoses, the spacer plate is the backbone of your engine's sealing system. These CAT engine parts are vital for maintaining correct liner protrusion and ensuring your head gasket receives uniform clamping force. By selecting these Cat engine performance parts, you protect your C15 or 3406E from the deck wear and coolant erosion that can lead to catastrophic block damage. Enhanced Power Products ensures that every plate provides the durability needed for high-boost, heavy-haul applications. Order today.

Expert Technical Support: Why shop with us? We offer deep industry knowledge to ensure you get the exact fitment for your specific engine serial number.
