this lock tool can be removed from the spring.

VVT spring lock tool and the instructions required for proper installation. This kit limits cam movement to 20 degrees.

this kit has everything that you need to limit the cam timing of your '07-'08 GEN IV and '14+ LT1 to 22 degrees.

this kit has everything that you need to limit the cam timing of your '09+ GEN IV and '14+ LT1 to 22 degrees.

The 7.3L Godzilla Cam Phaser Limiter Kit #5473 restricts cam phaser motion for high-performance camshafts creating a broader powerband. Limiter notch ensures stock oil flow is not impeded and disassembly tool is included for easier install.

• Combines the benefits of a larger camshaft with the benefits of stock cam phaser technology to make a broader powerband.
• Included tool for phaser disassembly makes installing the limiter much easier.
• Limiter notch ensures stock oil flow is not impeded.

This cam phaser limiter kit for GM LT4 engines allows for the installation of a high performance camshaft while also retaining the benefits of variable valve timing technology.

• Increases valve clearance for install of high-performance cams
• Allows simultaneous phaser spring compression
• Engages spring lock in optimal location
• Maintains VVT technology benefits
• For 2015 and newer GM LT4 engines
• Tool available separately
• without limiter plug

The 7.3L Godzilla Cam Phaser Lockout Kit #5474 prevents the VVT phaser from moving the cam installed centerline and provides more piston-to-valve clearance for large cams. Installation tool included for easier installment.

• Lock prevents VVT phaser from moving the camshaft installed centerline
• Increases piston to valve clearance for larger camshafts.
• Installation tool provided for easier installment.
