Honda TRX 400 EX Camshaft - Hot Cams - Stage 3 - `99-`08 is a purpose-built performance camshaft for the Honda TRX 400 EX single-cam models. Stage 3 is aimed at riders and tuners seeking stronger top-end power while maintaining usable midrange performance.

This Hot Cams Stage 3 camshaft is dyno-proven in the USA and engineered with modern valvetrain software to refine lobe profiles for reliable operation. CNC-machined from 8620 billet, case-hardened steel, it provides a precise fit and durable surfaces for long service life. Designed for straightforward installation, the cam can deliver an estimated 5–10% power gain over stock depending on vehicle condition and supporting modifications. Multiple stages (Stage 1–3) are offered across the Hot Cams line so you can choose the profile that best matches your riding goals, from improved low-end torque to increased peak horsepower. No core exchange is required.
