• Description:

  Genuine Ford OEM secondary timing chain part number HL3Z-6268-A, the smaller-pitch chain that connects the cam phasers across each cylinder head. This timing chain fits 17-25 Ford F-150 trucks with the 3.5L EcoBoost, 18-25 Expedition with the 3.5L EcoBoost, and 18-25 Lincoln Navigator with the 3.5L EcoBoost. The secondary timing chain is part of the well-documented Gen2 3.5L EcoBoost timing system wear issue, where chain stretch combined with phaser bearing wear produces a characteristic cold-start timing rattle. Ford technical service bulletins call for replacement of the full timing set including the primary chain, secondary chains, all guides, tensioners, phasers, and torque-to-yield fasteners as a complete service job. Individual chain replacement is rarely sufficient since wear is typically distributed across the entire timing system. The chain ships with the factory lubricant and packaging that protects the rollers and pins during transit. Installation requires the full timing service procedure following the workshop manual, including timing alignment marks, tensioner reset, and final timing verification with the scan tool. Ships in original Ford packaging with the standard Ford limited parts warranty.

• Applications: 3.5L.
