F-150 Lockout System with Tuner Device (2004-2010)
Ensure precise engine timing control with phaser timing lockout kit. Billet aluminum inserts install into the stock phaser and prevent movement and failure in 2004+ 5.4 3V engines. Billet aluminum inserts lock phasers remedying the common VCT system failure while the tuner provides the necessary modifications to compensate for the lockouts.
