Are you pursuing the absolute maximum naturally aspirated power from your Honda K-series engine? The Drag Cartel 004.5 Camshafts are the result of rigorous, high-end race and dyno testing, engineered to deliver the most aggressive performance profile available for dedicated all-motor racing applications. These cams are the key to unlocking the K-series engine’s full, untapped potential.

Why are 004.5 Cams built for extreme performance?

The 004.5 cams feature an extremely aggressive profile that maximizes airflow and top-end horsepower, making them essential for serious track use and competition builds

• Ultimate Horsepower: The high lift and duration specifications are designed for peak naturally aspirated performance, ensuring maximum airflow through the cylinder head.
• Aerospace-Grade Rigidity: Constructed from 8620 steel billet material, these cams provide superior strength and stiffness, which is crucial for reducing valve float and maintaining stability at sustained, extended RPM ranges.
• Precision Engineering: CNC-ground profiles ensure accuracy and faster valve action, taking full advantage of the K-series roller rocker design.
