COMP Cams 5448 Cam Phaser Limiter Kit for Ford Modular Engine Variable Timing Adjuster Plug - 4.6L 5.4L 3-Valve

The COMP Cams 5448 Cam Phaser Limiter is engineered to address common cam phaser failure issues in 2005 and newer Ford 4.6L and 5.4L 3-valve modular engines. This precision-machined limiter kit restricts the range of motion in the variable cam timing system, preventing the excessive phaser travel that leads to timing chain rattle, rough idle, and check engine lights.

Key Features:

• Direct fit for Ford 4.6L and 5.4L 3-valve modular engines (2005 and newer)
• Limits cam phaser travel to prevent common failure modes
• Eliminates timing chain rattle and phaser noise at startup
• Helps prevent catalytic converter damage from retarded timing
• Cost-effective alternative to complete phaser replacement
• CNC-machined from high-quality materials for precise fitment
• Includes installation hardware and instructions

This phaser limiter kit is ideal for vehicles experiencing cold start rattle, rough running conditions, or P0340-P0349 cam position sensor codes related to phaser timing issues. Installation requires removal of the cam phasers but allows reuse of existing components when they are not severely damaged. Compatible with popular Ford applications including F-150, Expedition, Mustang GT, and Explorer equipped with 3-valve modular engines.
