Cylinder Heads & Related Components for Cummins ISX Single Cam Engines

The Cummins ISX Single Cam engine is a heavy-duty powerplant designed for marine and industrial applications that demand performance, fuel efficiency, and long service life. A crucial part of this engine’s reliability lies in the cylinder head assembly. The cylinder head houses the valves, injector tubes, and various seals and gaskets that ensure proper combustion, airflow, and fuel delivery.

At Diesel Pro Power, we provide a complete selection of cylinder heads and supporting components for Cummins ISX Single Cam engines, ensuring you can rebuild or service your engine with confidence. With more than 40,000 satisfied customers worldwide, we are the trusted source for quality Cummins parts.

Complete Cylinder Head Assemblies

New Cylinder Head for Cummins ISX Single Cam Engines

We offer brand-new cylinder heads for ISX engines equipped with a single overhead camshaft. These heads come fully assembled with valves installed for easy installation. The camshaft itself is not included, allowing you to reuse your existing camshaft or purchase separately if required.

• Designed specifically for single cam ISX and QSX engines.

• Includes intake and exhaust valves pre-installed.

• Ensures proper airflow, compression, and durability under heavy duty conditions.

Cylinder Head Fastening Components

Head Bolt Kit for Cummins ISX and QSX Engines

When replacing a cylinder head, it is essential to use a complete head bolt kit. Our kits include every bolt required for proper installation, ensuring correct torque specifications and secure sealing.

• Provides all hardware necessary to mount the cylinder head.

• Ensures long-term reliability under high compression loads.

• Suitable for both ISX and QSX models.

Valve Train Components

Intake Valves

High-quality intake valves regulate the flow of air into the combustion chamber. Manufactured to OEM standards, these valves are designed for durability and precise sealing.

Exhaust Valves

Exhaust valves manage the exit of combustion gases. Built to withstand extreme heat and pressure, they help maintain engine performance and efficiency.

Valve Inserts (Seats)

• Intake valve inserts provide a hardened surface for the intake valves to seal against.

• Exhaust valve inserts are designed to resist high-temperature wear for long-term reliability.

Valve Guides

Durable valve guides ensure proper alignment of the intake and exhaust valves, reducing wear on the valve stems and improving sealing efficiency.

Valve Seals

Valve seals for both intake and exhaust prevent oil leakage into the combustion chamber, helping reduce smoke, oil consumption, and emissions.

Fuel Injector Tube Components

Injector Tube Kits for ISX and QSX Engines

The injector tube is critical for delivering fuel into the combustion chamber. We carry two versions:

• Kit with seal included – ready-to-install with proper sealing.

• Kit without seal – for customers who wish to replace seals separately.

Injector Tube Seals

Replacement seals for injector tubes ensure leak-free operation and reliable fuel delivery.

Gaskets and Sealing Components

Upper Gasket Sets for Cummins ISX Engines

We provide complete upper gasket sets to properly reseal the cylinder head and related components.

• For non-EGR engines – designed for older configurations without exhaust gas recirculation.

• For EGR-equipped engines – includes gaskets optimized for engines with EGR systems.

Valve Cover Gaskets

High-quality valve cover gaskets prevent oil leakage from the top of the engine. Available in both new style and old style designs for different ISX engine builds.

Vibration & Noise Control

Vibration and Noise Isolators

To reduce vibration transfer and protect engine components, vibration isolators are used in ISX and QSX engines.

• For engines built from 2010 and newer – updated isolator design with included screw.

• For engines built between 2003 and 2009 – earlier style isolator with included screw.

Temperature Control Components

Temperature Switch

We also carry temperature switches compatible with Cummins, Detroit Diesel, and Caterpillar engines. This switch activates at 205°F and uses a ½” NPT thread size, providing reliable engine protection from overheating.
