Upgraded Bosch CP4 Camshaft – High Performance Fuel Delivery up to 750HP

Unlock the full potential of your high-pressure fuel system with our upgraded Bosch CP4 camshaft, engineered for performance, durability, and consistent fuel delivery in demanding applications. Designed in-house by Stopping Power Ltd, this camshaft supports builds of up to 750 horsepower, delivering stable common rail pressure even under extreme load conditions—making it the ideal choice for high-performance and competition diesel engines.

At the core of this upgrade is the use of 20CrMo alloy steel, a material specifically selected for its exceptional mechanical properties. 20CrMo offers outstanding hardenability, fatigue resistance, and core toughness, which are critical in high-load, high-contact stress environments like CP4 fuel pumps. Its chromium-molybdenum composition enhances wear resistance and structural integrity, ensuring long-term reliability where lesser materials would fail.

To further maximize durability, each camshaft undergoes a precise carburizing and quenching heat treatment process. Carburizing creates a hardened outer surface layer with superior resistance to wear and scuffing, while maintaining a tough, ductile core that absorbs shock and prevents cracking. The subsequent quenching process locks in this hardness, resulting in a component capable of withstanding the intense pressures and repeated stress cycles of high-performance fuel systems.
