All About the Stage 4 Performance Cylinder Head
Stage 4 Cylinder Head Caterpillar
As we said earlier, this is the ultimate cylinder head you can put on your 3406E, C15, or C15 ACERT.
It can handle the extra horsepower from your upgraded components.
Upgraded Valves
Just like the Stage 3 Head, this cylinder head comes with all the valves upgraded. We’re talking both intake and exhaust.
You’ll be getting valves made from inconel material. This allows them to handle the higher temperatures and pressures thrown at them.
You’ll see Inconel material most frequently in racing, super-charged, turbo-charged, and boosted applications.
Chordal Fracture
If you push a valve beyond its temperature and pressure capabilities, you might end up with something called chordal fracture.
To prevent this, the valves are generally upgraded in performance series engines. The inconel material means stronger, more durable valves and a longer-lasting cylinder head.
Fire Rings
With this head, you’ll also be getting fire rings. The deck has been machined around each cylinder for the fire rings.
To do this, a groove is cut and a stainless steel ring inserted. This helps stop head gasket blow outs.
This means that when you’re running an engine with high pressure and high horsepower, this head can keep up.
Head Materials
This head comes from a solid foundation. It brings a higher coolant flow to the table, and you’re getting higher nickel content and an improved casting.
This head has the stuff to last.
What Are the Benefits of the Stage 4 Performance Cylinder Head?
This head features all the great benefits you want in a performance head—inconel valves, fire rings, and an industry leading warranty!
It’s made specifically for high horsepower engines, so you don’t need to worry about whether or not it can handle the extreme operating conditions. It maintains structural integrity under high pressure, and it resists oxidation, pitting, corrosion, and cracking.
You’re also going to be getting new valve springs, new valve keepers, and new spring retainers. The cam bearings come pre-installed.
If you’re looking for the best option for your Caterpillar 3406E, C15, or C15 ACERT, the Stage 4 Performance Head might be just what you need!
