EXCELLENT TOOL Review by Robi

The tool worked perfectly. I used it on a 2014 F150 with a 5.0L. One of the right hand exhaust valve rockers failed. Was able to push the valve spring down and remove and install the new rocker in minutes once the tool was installed!! (Posted on 11/10/2021)

Clever tool, delivered in a hurry! Review by William

The other tools on the market for changing valve springs on a Coyote require you to remove the cams, which means removing the timing chain cover and removing the chains and the TVIct mechanisms. With this tool everything stays in place as you sequentially remove the cam retaining caps. The forks provide enough access to install taller heavier springs as well. Great tool from a great company!

Tool works Review by Matthew

Bought the tool because it was described to replace the valve springs with cams installed. This was not the case as the rear springs could not be removed with the cams installed.
The tool itself is built good and works but it you plan on doing all your springs with the cams in this is not the tool for you (Posted on 6/1/2020)

Amazing Review by Dallis

If you have a broken valve spring then this is the tool to go around pulling the cams and having to re time the engine. What would of been a 15+ hour job turned into a 2 hour job, just make sure you stuff a rag into the head so you don’t drop a keeper. (Posted on 5/20/2020)
