Tork Tek CVSC020 Cummins 5.9 Valve Spring Compressor for the 12-Valve

This spring compressor is great and instructions were very good, just take your time when you do it and dont forget only two cyllinders at a time, then find tdc on the next set and for the third, fyi do your valve stem seals at the same time!

I usually don’t spend time reviewing products unless they are horrible or phenomenal. This tool is definitely the latter! If you plan on doing any valve or valve spring work on 12 Valve Cummins, this tool is what you want. Good instructions, well built and does both springs at once.

This is well worth the money. I used it on a 1995 12 valve. Very easy to use, it's built to line up on the same mounting ring as the rocker pedestal.

works as described and made it so much easier to install new valve springs for my exhaust and intake springs

Yes they fit a cummins 5.9 12v, works great

Replacing the rear springs without this would almost be impossible!

Nice hardware and machining

Worked as inteded!
