A-Premium 17PC Timing Chain Kit for 4.0L SOHC V6 — Complete OEM-Style Replacement with Tensioners & Guides

A-Premium's 17-piece engine timing chain kit is a complete OEM-style replacement set engineered to restore correct valve timing for 4.0L SOHC 6-cylinder Ford, Mazda and Mercury engines.

This comprehensive kit supplies the chains, tensioners, sprockets, guides and hardware needed to replace worn timing components on compatible 4.0L SOHC V6 engines. It’s designed to fit factory specifications for Explorer, Ranger, Sport Trac, Mountaineer and Mazda B4000 model years listed, delivering a full drivetrain timing overhaul in one package so you don’t have to source individual parts.

What exactly is included in the 17-piece kit?

The kit bundles primary and secondary chains, tensioners, sprockets and all guide rails and mounting elements required for a complete timing system refresh. Components are matched to the parts referenced by multiple OEM numbers, making it straightforward to replace the entire timing train in a single job.

• 2 cam-to-jackshaft timing chains and rear jackshaft chain
• Front & rear cam tensioners plus jackshaft tensioner
• Front/rear cam sprockets and jackshaft sprockets
• Cam chain guides, jackshaft fixed guide, balance-shaft tensioner and guide
• Oil line restrictor and assorted OEM-equivalent hardware

Which vehicles and engines does this kit fit?

This A-Premium kit fits single overhead cam (SOHC) 4.0L V6 engines used in specific Ford, Mercury and Mazda vehicles. Confirm fitment by cross-referencing your vehicle year and engine type; the kit is intended only for SOHC 6-cylinder 4.0L applications.

• Ford Explorer: 1997–2010 (also Explorer Sport Trac 2002–2005, 2007–2010)
• Ford Ranger: 2001–2010
• Mazda B4000: 2001–2010
• Mercury Mountaineer: 1998–2010

How does this kit compare to OEM parts and what are the benefits?

Parts are produced to meet OEM-style specifications and include hardened chains, precision sprockets and wear-resistant guides. The materials and manufacturing process aim to provide stable timing performance, reduced friction and extended service life versus severely worn original components.

• Manufactured to OEM dimensions for straightforward interchange
• High-durability chains and wear-resistant guide rails
• Designed to maintain consistent transmission of timing loads
• Includes all necessary components to avoid piecemeal repairs

What should I expect during installation and maintenance?

Installation typically requires engine timing alignment, torque-specified fasteners and proper tensioner preload. Because the kit replaces the whole timing train, take the time to follow service manual procedures, verify timing marks, and inspect related systems such as the water pump and cam seals while you have access.

• Follow factory service manual for timing alignment and torque specs
• Replace ancillary items (seals, water pump) if wear is present
• Check oil pressure and restrictor placement during assembly
• Verify tensioner operation and chain slack after initial run-in

Who is this for: This 17-piece A-Premium timing chain kit is aimed at DIY mechanics, independent shops and restoration projects that need a full timing system replacement for 4.0L SOHC 6-cylinder engines in supported Ford, Mazda and Mercury models. It’s ideal when you want a complete, OEM-spec replacement set—especially if multiple timing components show wear or if accurate, long-term timing performance is a priority. A-Premium backs the kit with a one-year unlimited-mileage warranty for additional confidence.
