Single-Piece Duralumin Construction:

The Tomei cam gear features single-piece duralumin construction, which provides superior strength and reliability compared to multi-piece designs. Duralumin is a high-strength aluminum alloy that's lightweight yet incredibly strong, making it ideal for high-RPM applications. The single-piece design eliminates the possibility of slippage that can occur with multi-piece gears, ensuring your cam timing stays exactly where you set it.

±20° Adjustment Range:

The cam gear provides ±20 degrees of adjustment, allowing you to advance or retard cam timing to optimize power delivery for your specific application. Advancing timing typically improves low-end torque and turbo response, while retarding timing can increase top-end power. The wide adjustment range gives you complete control over valve timing to match your engine build and power goals.

Laser-Etched Degree Markings:

Precise laser-etched degree markings make it easy to see and adjust cam timing accurately. The clear markings ensure you can set timing precisely and repeat settings consistently. This is critical for tuning and ensures you can document your settings for future reference.

Why Adjust Cam Timing?

Adjustable cam gears allow you to optimize valve timing for your specific application:

• Stock Turbo Builds: Advance timing for better low-end response and torque
• Big Turbo Builds: Retard timing for increased top-end power and higher RPM capability
• Drag Racing: Optimize for maximum power in specific RPM range
• Drift/Circuit: Balance low-end response with top-end power
• Compensation: Correct timing after cam or head work

1JZ-GTE and 2JZ-GTE Compatibility:

This cam gear fits both 1JZ-GTE and 2JZ-GTE engines, making it a versatile choice for Toyota inline-6 turbo builds. The same gear works on both engines, simplifying inventory and ensuring you get the proven Tomei quality regardless of which engine you're building.
