Comp Cams Cam Phaser Lockout Kit GM GEN V LT4 5471

Variable valve timing is a double-edged sword for forced induction—it improves efficiency at cruise but destabilizes boost response when you need it most. The Comp Cams Cam Phaser Lockout Kit locks your cam timing at peak performance settings, eliminating phaser lag and delivering consistent, predictable power delivery across the entire RPM range. For serious tuners and track-focused builds, this kit removes a variable that can cost you tenths on the dyno.

This is a straightforward bolt-on solution designed specifically for the GM GEN V LT4, requiring no fabrication or tuning adjustments to install.
