5.0 Coyote Secondary Tensioner bracket

tensioner xtensioner x 2

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 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 PATENT PENDING part from MMR fixes the problem by essentially flipping the tensioner upside down with a simple billet bracket and 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.
