Dual Overhead Cam (DOHC) Products

At Behind the 8, we know the importance of Dual Overhead Camshaft (DOHC) technology–it powers engines that face heavy workloads day in and day out. Our high-quality parts for DOHC engines are backed by decades of hands-on experience. 

Unlike Single Overhead Camshaft (SOHC) systems, dual overhead camshaft engines feature two camshafts for precise valve timing and efficient airflow—one for intake valves, the other for exhaust valves. 

Here’s why DOHC configurations excel in real-world applications:

• Improved Valve Timing: The separation of intake and exhaust valves allows for optimal timing and engine performance under load.
• Higher Engine Speeds: This design supports smooth operation at higher revolutions, which is essential for consistent power delivery.
• Smaller Engine Displacement: DOHC systems make it possible to pack more power into compact engine designs, a benefit for equipment and vehicles where space and weight are at a premium.

Whether you’re managing a fleet of highway trucks or operating heavy equipment, DOHC engines bring a level of efficiency and responsiveness that can handle these tough conditions.

DOHC Components We Support

When it comes to maintaining or repairing your DOHC engine, you need top-quality parts; 

Cylinder Heads

The cylinder head is the cornerstone of every internal combustion engine. It houses the intake valves, exhaust valves, and camshafts, maintaining proper compression and airflow. Faulty or worn cylinder heads can lead to performance loss or engine failure—issues we’re here to help prevent.

Camshafts

In a dual overhead camshaft setup, two camshafts work in tandem to control the engine’s airflow. Properly functioning camshafts ensure balanced valve operation, keeping your engine running smoothly. Issues like uneven wear or timing misalignment? They’re best resolved with quality replacements designed to meet OEM standards.
