Here is a great new "PATENT PENDING" part from MMR, developed and tested by the Fastest 5.0 Coyote engines in the World! Ford is notorious for tensioning chains on the wrong side and the 2018+ 5.0 coyote was no different. Long story short the chains should always be tensioned on the "slack" or loose side. Unfortunately Ford missed the boat again so to speak, and the driver side cylinder head on ALL coyote 5.0 engines are tensioned on the wrong side. Many will ask "what does it do?", the answer is it allows for a large sweep (5-6 degrees) of uncontrolled timing and racheting of the cam which is very hard on timing chains and allows for erratic cam timing, for those that have ever degreed a modular engine some will notice that it is very hard to make the cams repeat after a few revolutions, this is one reason.
This new part from MMR fixes the problem by essentially flipping the tensioner upside down with a simple billet bracket which also helps eliminate secondary chain failure. The kits includes the MMR billet bracket and ARP hardware. The Cam sprockets must be removed for installation, otherwise it is a very easy install and should be considered for any serious build.
Like all MMR components this part is Proudly made in USA!
Provisional Patent Number 62/647,350
*In Mid 2020 Ford Performance Aftermarket Timing Kits switched to a shorter Secondary Tensioner, the short version is NOT compatible with the MMR tensioner bracket. If you have a timing kit with the short tensioners you will need to purchase MMR PN#450484 tensioners to use this bracket.
