First time doing any kind of valve train work whatsoever and this tool is awesome. Very well made, machining is top notch. Very smooth operation and the anodizing makes it something you’ll be proud to have in your tool collection.

Tool worked great, very well made.

Made the job a piece of cake

This tool worked better than I would have imagined. Very slick compression and quick to use. Very heavy duty and safer than the other tools I have seen. Made the job easy, even with the motor in the truck.

This worked amazing on my 1995 7.3 valve spring swap. Much safer tool than the standard one I could find elsewhere.

Work very well! Rated a 4 because I’m not sure I could use this tool if the heads were still on the truck. The tool construction is spectacular. It’s a bit expensive as well but it’s so well made and works so well it’s worth the money. My only complaint is usability if the heads are mounted in the truck.

Ford should once again take note of the engineering that Riffraff diesel puts into their tools. This made the job so easy, and honestly so much safer than any other tool I could get. Glad to have this tool in my box.

This is by far the best valve spring tool I have ever used. Much safer and easier to use than others, and it is very stout.

Amazing quality as expected from Riffraff. Tool functions very smooth and makes this job much easier and safer.
