• Description:

  Genuine Ford OEM right-hand timing chain guide part number HL3Z-6B274-B, the passenger-side slack-side guide that controls primary timing chain motion on the 3.5L EcoBoost engine. This guide fits 17-25 Ford F-150 with the 3.5L EcoBoost, 18-25 Expedition with the 3.5L EcoBoost, 18-25 Lincoln Navigator with the 3.5L EcoBoost, and 17-22 Ford GT with the 3.5L EcoBoost. This guide is the counterpart to the left-hand HL3Z-6B274-A and shares the same Gen2 3.5L EcoBoost wear characteristic, where the plastic guide face wears prematurely and produces a characteristic cold-start timing rattle. Ford technical service bulletins call for replacement of the full timing set including both guides, both tensioners, all chains, all phasers, and the related torque-to-yield fasteners as a complete service job. Individual guide replacement is rarely sufficient since wear is typically distributed across the entire timing system. The guide ships with the factory plastic surface specification and the steel reinforcement structure. Installation requires the full timing service procedure. Ships in original Ford packaging with the standard Ford limited parts warranty.

• Applications: 3.5L.
