Tensioner Timing Chain RH Ford 4.0L V6 97-11

The Tensioner Timing Chain RH Ford 4.0L V6 97-11 by CLOYES is a critical engine management component designed for right-hand timing chain tensioning on Ford's legendary 4.0-liter V6 platform. This tensioner maintains proper chain slack throughout the engine's RPM range, preventing chain whip and valve timing drift that can destroy engine performance or cause catastrophic internal damage. Whether you're restoring a high-mileage Explorer, Ranger, or Mustang, or rebuilding after a timing chain failure, this OEM-quality tensioner is non-negotiable for long-term reliability.

CLOYES tensioners use spring-loaded piston designs that automatically compensate for chain stretch over time, maintaining consistent valve timing without manual adjustment. The right-hand tensioner specifically controls tension on the passenger-side chain run of Ford's dual-chain architecture, working in concert with the left-hand unit to keep both chains perfectly indexed. The compact 4.6 x 1.8 x 4.75-inch profile fits precisely into the factory mounting location, and at 0.42 lbs, it integrates seamlessly into your engine bay without adding unnecessary weight. CLOYES manufacturing adheres to strict OEM tolerances, ensuring that critical bearing surfaces and piston action respond predictably across the full operating temperature range.

Mechanics and enthusiasts working on 1997–2011 Ford 4.0L V6 engines—particularly those in Rangers, Explorers, Mountaineers, and edge-case applications like modded Mustangs—depend on this tensioner during timing chain service. Installation requires removing the timing cover and is best paired with a full timing chain kit replacement, new gaskets, and proper valve timing verification using a degree wheel. If you're experiencing stretched chain symptoms (rough idle, timing variance codes, or audible chain rattle at cold start), this CLOYES unit delivers the reliability needed to restore OEM performance and protect your investment for the next 150,000 miles.
