Complete secondary timing chain Tensioner Kit for 4.6L and 5.4L 4V only Ford Modular motors. This kit includes both passenger and driver side tensioners and two heavy duty secondary chains, which provide 50% more tensile strength. Both tensioners are designed to use significantly less oil during operation and also uses a custom one piece plunger assembly. Furthermore, the passenger side tensioner is designed to tension on the correct side of the chain. JDM Engineering trusts Accufab for manufacturing the highest quality parts for modular and coyote platforms, and never sacrificing on quality!
