Benefits of this Performance ISX SOHC (Single Overhead Camshaft) Cylinder Head:
Brand New & Fully loaded Cummins ISX & ISX15 Single Overhead Camshaft Cylinder head. Our castings are engineered, designed, and assembled in the U.S.A. They are better than OEM quality containing 5% more nickel content in the casting material. This additional nickel content prevents the cylinder head from cracking in between the valves. Additionally, the coolant passages have been enlarged by 30%, and inner ribs have been reinforced to reduce heat stress. If you have been a victim before of a cracked cylinder head, you know just how costly that it can be! Don't take the chance by buying an OE reman cylinder head that is bound to crack again. Upgrade with our Enhanced Performance Cylinder head and enjoy the peace of mind while hauling across the country!
What is this Enhanced Performance all about?
This performance cylinder head is an upgrade from the standard cylinder head. On top of the interior upgrades to the actual casting itself, the intake valves in this cylinder head have all been upgraded to inconel valves. This major performance improvement increases the capacity of the valves to endure higher temperatures as well as heightened pressure.
There is a common fracture issue with standard valves when they are running at heightened horse-power, this superior quality inconel material prevents these types of fractures and ensures that your exhaust valves can stand the heat! If you are looking to get more out of your engine and ensure that your head doesn't fall prey to corrosion, pitting, and cracking; this is the head for you!
