These cam phaser lockouts are designed to allow the use of aftermarket springs and camshafts while still retaining the stock phaser. The lockouts are two piece anodized billet aluminum and designed to fit within the stock phaser. These lockouts are designed to limit the total travel of the cam phaser. They eliminate the durability issues associated with the phasers and allow the use of larger aftermarket camshafts and springs.

These cam phaser lockouts for the Ford 5.0 engines are designed to allow the use of aftermarket springs and camshafts while still retaining the stock phaser. The lockouts are single piece anodized billet aluminum and designed to fit within the stock phaser. The use of aftermarket valve springs with increased spring pressure, as well as aftermarket camshaft profiles do not allow the factory Ford cam phaser to function properly and may even cause it to fail. The increased spring pressures and more aggressive camshaft ramp rates cause the phaser to behave erratically. The factory phaser cannot control these added pressures, and in the majority of cases the phaser will emit a knocking noise as the phaser struggles to control the camshaft position. These solid lockouts lock the internals of the cam phaser to create a fixed gear with no moving parts.
