HKS 22004-AT002 Adjustable Cam Gear Timing Gear

HKS Adjustable Cam Gears provide precise control over camshaft timing to optimize engine performance and customize power delivery across different driving conditions. These performance cam gears work with both OEM and HKS aftermarket camshafts, allowing tuners to shift the engine's power band to the ideal RPM range for specific applications—whether street driving, road racing, or drag racing.

Premium Construction:

• Manufactured from lightweight anodized Duralumin to reduce rotational mass and engine drag
• Nickel-plated gear teeth for durability and wear resistance
• Laser-etched Vernier scale markings for precise adjustment
• Clear directional markers: A (advance) and R (retard) etched on gear face

Adjustment Range and Precision:

• 20-degree total adjustment range for fine-tuning cam timing
• 2-degree interval markings for repeatable, accurate settings
• Allows optimization of valve overlap, low-end torque, or high-RPM power

HKS engineers selected Duralumin alloy specifically for its exceptional strength-to-weight ratio, which minimizes parasitic drag on the engine while maintaining the structural integrity required for precise valve timing control. For applications using timing chains rather than belts, HKS utilizes an aluminum slide plate with steel teeth to ensure proper chain engagement and longevity.

Adjustable cam gears are essential tuning tools for naturally aspirated and forced induction engines, enabling tuners to compensate for modified components like aggressive camshaft profiles, aftermarket turbochargers, or high-compression builds.
