Product Description:

Industrial Injection New 3406E, C15, ACERT Upgraded Cylinder Head With Inconel Valves

Upgrade the reliability and performance of your Caterpillar diesel with this new upgraded cylinder head for CAT 3406E, C15, and ACERT engines. Built from 100% new castings and equipped with Inconel intake & exhaust valves, this cylinder head is engineered to handle extreme heat, high exhaust gas temperatures, and heavy-duty applications where stock heads fall short.

Designed as a direct-fit replacement, this upgraded cylinder head is ideal for on-highway trucks, vocational equipment, agricultural machinery, and performance or high-horsepower builds. Inconel valves provide superior resistance to cracking, warping, and valve failure, making this head a smart upgrade for both stock and modified engines.

Key Features & Benefits

  • Brand New Universal Cylinder Head – Not remanufactured

  • Inconel Intake & Exhaust Valves – Extreme heat resistance and long service life

  • Compatible with CAT 3406E, C15 & ACERT engines

  • Upgraded valve materials for improved durability under high EGTs

  • Precision machined for proper sealing and factory-correct fitment

  • Direct bolt-on replacement – No modifications required

  • Ideal for heavy hauling, towing, performance, and commercial use

Why Choose Inconel Valves?

Inconel is a high-nickel alloy specifically designed for extreme environments. Compared to standard stainless valves, Inconel valves offer superior strength, oxidation resistance, and thermal stability, significantly reducing the risk of burnt valves or premature engine failure—especially in high-load or tuned applications.

Applications

  • CAT 3406E

  • CAT C15

  • CAT C15 ACERT

  • On-highway trucks

  • Off-road and vocational equipment

  • Performance and high-horsepower diesel builds

Built for Reliability & Performance

Whether you’re replacing a failed cylinder head or building a more durable engine, this CAT 3406E, C15, ACERT upgraded cylinder head with Inconel valves delivers long-term reliability, improved heat management, and confidence under demanding conditions.

Perfect for stock replacements, fleet maintenance, or performance upgrades.
