Engine Timing Chain Kit with Chains, Tensioners, Sprockets & Guides for Ford, Mercury & Mazda 4.0L V6

Engine Timing Chain Kit for Select Ford, Mercury, and Mazda 4.0L V6 Applications

Multi-piece timing-chain service kit containing four chains, two tensioners, seven sprockets, and six guide rails for the exact 4.0L V6 model-year applications listed below.

Critical fitment warning: Every listed application is restricted to the 4.0L V6. The source does not provide the engine code, VIN digit, camshaft configuration, production date, drivetrain, transmission, chain dimensions, timing-system revision, or formal replacement reference numbers. Ford 4.0L applications can use configuration-specific timing components. Confirm the VIN, engine label/code, original timing layout, chain count, sprocket profiles, tensioner design, guide shapes, timing marks, and required service parts before ordering.

Ford Compatibility

• 1997–2010 Ford Explorer — 4.0L V6
• 2001–2003 Ford Explorer Sport — 4.0L V6
• 2001–2005 Ford Explorer Sport Trac — 4.0L V6
• 2001–2011 Ford Ranger — 4.0L V6
• 2005–2010 Ford Mustang — 4.0L V6

Mercury Compatibility

• 1998–2010 Mercury Mountaineer — 4.0L V6

Mazda Compatibility

• 2001–2009 Mazda B4000 — 4.0L V6

Not confirmed: Other engine sizes, V8 applications, model years outside these ranges, or any 4.0L V6 timing system that does not physically match the original chains, sprockets, guides, and tensioners.

Confirmed Kit Contents

• 4 timing chains
• 2 timing-chain tensioners
• 7 sprockets
• 6 guide rails

The source does not identify the position of each individual chain, sprocket, tensioner, or guide. Camshaft cassettes, jackshaft hardware, VVT components, seals, timing-cover gaskets, valve-cover gaskets, crankshaft bolt, fluids, special tools, and other installation hardware are not confirmed as included.

Reference Information

No OE or replacement reference numbers are provided in the source description. The SKU is an inventory identifier and is not used as proof of engine configuration, kit interchange, or an OE reference.

Installation Notes

Timing-chain replacement on a 4.0L V6 is an advanced engine repair and should be performed by a qualified technician. Obtain the exact service procedure for the VIN and engine code before disassembly. Confirm all timing marks, chain and sprocket positions, locking-tool requirements, tensioner preparation, torque values, torque-angle specifications, sealant locations, and one-time-use fasteners. Depending on the exact engine layout and chain position, substantial component removal may be required; the source does not define the service procedure.

Inspect every original chain, sprocket, guide, tensioner, oil passage, timing cover, and related sealing surface. After assembly, rotate the engine by hand through the specified number of revolutions and recheck all timing marks before starting. Restore fluids correctly, verify oil pressure, scan for timing-related faults, and check for leaks or abnormal noise.

Frequently Asked Questions

Does this kit fit every 4.0L Ford engine?
No. It is limited to the specific model and year entries listed above, and the exact engine code and original timing layout must match.

Does it fit V8 models?
No V8 application is listed. All source-supported entries are 4.0L V6.

Are all four chains included?
Yes. The confirmed contents list four timing chains, two tensioners, seven sprockets, and six guide rails.

Are gaskets, seals, and installation hardware included?
They are not listed in the confirmed contents. Review the vehicle-specific service procedure and obtain all required sealing materials, fluids, fasteners, and tools separately.
