Timing Chain Kit 5L3Z6268A Fit for 2002-2008 Ford F-150 Expedition E-150 5.4L V8

This timing chain kit is designed to replace worn timing components and help restore accurate crankshaft-to-camshaft synchronization on compatible Ford engines. It includes two timing chains, camshaft and crankshaft sprockets, tensioners, and guides for timing-system repairs where chain or related component wear has been confirmed.

Product Features

• Two 122-link timing chains: Allows both chains to be replaced during the same repair rather than leaving one worn chain in service.
• Camshaft and crankshaft sprockets included: Replaces the chain-contact surfaces alongside the chains, avoiding the pairing of new chains with worn sprockets.
• Separate tensioners and guide components: Two tensioners, two chain guides, and two tensioner guides work together to maintain chain tension and guide chain movement.

Important Notes

• Please verify the OE/reference number and vehicle information before ordering.
• Confirm the engine displacement, valve configuration, and model year against the fitment information. Vehicle model alone does not establish compatibility.
• Check the reference numbers and installation positions of the tensioners and guides, as these components are position-specific.
• Engine rattling and timing-related fault codes can have multiple causes. Confirm the source of the problem before replacing timing components.
• Follow the vehicle manufacturer’s timing alignment, tensioner setup, and bolt-tightening procedures during installation.
