HKS Adjustable Exhaust Cam Gear - Toyota 4A-GZE 5-Valve (Exhaust Side)
The HKS Adjustable Exhaust Cam Gear is designed for Toyota 4A-GZE 5-valve engines, allowing precise adjustment of exhaust camshaft timing to optimize horsepower, torque, and throttle response. By fine-tuning the valve timing to suit the engine setup and other performance modifications, the engine's powerband can be optimized for both high-performance street and motorsport applications.
The cam gear is manufactured from A2014 duralumin, a lightweight, high-strength aluminum alloy that offers approximately 50% greater strength and 30% higher hardness compared to previous versions. The optimized design reduces rotating mass and engine load, contributing to improved reliability and more efficient power delivery.
The gear section features a nickel-plated finish that increases surface hardness and improves anti-friction properties. This hardened surface provides excellent wear resistance and is designed to withstand the increased loads associated with reinforced timing belts and demanding operating conditions.
Designed as a direct replacement for the factory component, the cam gear provides OEM-style fitment for straightforward installation without modifications. It is an excellent upgrade for both stock engines and performance builds where precise valve timing adjustment is essential for achieving maximum performance.
