This is a very complete package. Makes changing valve springs a snap. The product is very well made and comes with everything you need including grease for the threads. The grease also works well for holding the valve keepers in place while you release the tension on the spring.

It is a bit spendy, but for what it does, it made my job super easy. ALSO, this comes with EVRYTHING you need. do not buy the retaining spring cap. I bought one cause the description said nothing of what this has so I wasted money and now have to return it.

In my opinion, this is the best compressor made for the 4.6l/5.4l 3v. The quality and function of the tool is top notch, simple set up and easy to use, getting the valve stem keeper out and in requires little effort when you get the hang of it. Highly recommended this tool to anyone changing valve springs.
