Product Description

The Skunk2 Pro-Series Adjustable Cam Gear Set (part 304-05-5225) is engineered for serious tuners running Honda H-series 2.2L DOHC VTEC engines (H22A/H22A4). By replacing the stock intake and exhaust cam gears with this lightweight, high-precision pair, you gain the ability to fine-tune cam timing ±10° in one-degree increments - allowing optimized power delivery, improved throttle response, and enhanced high-rpm performance.

Manufactured from CNC-machined 7075-T6 billet aluminum and finished with hard-anodized surfaces, the gear set delivers roughly 35 % weight savings over factory gears, reducing rotational inertia and allowing the engine's camshafts to respond more rapidly. The six-bolt design ensures secure mounting under extreme conditions, while laser-etched timing marks simplify accurate setup and repeatable tuning.

Ideal for performance builds, track day machines or high-rev street builds, this gear set is tailored for the 1993-2001 Honda Prelude models equipped with the H22A/H22A4 2.2L DOHC VTEC engine. Installation requires cam timing setup and verification - correct alignment is critical. This is not a "universal" cam gear set; fitment applies only to the specified engine and platform. **Fitment confirmed through 2001. 2025 coverage unconfirmed at time of listing.**
