Installed these in my Cummins 12V and what a difference they make! Power all throughout the RPM band. Quality looks good and no issues with the install.

Springs are great quality; I was very skeptical because of the price but have no regrets. Install was relatively easy, Power Driven Diesel has a great video for swapping these out that I recommend watching. I will emphasis BE CAREFUL when removing the old springs so you don't drop the shims into the AFC housing and have to sweat bullets while trying to fish them out with a small magnetic pickup (ask me how I know). I'm only running the 3k on my truck as I don't have upgraded valve springs and this definitely made a noticeable difference in my low & upper end power band.

Best upgrade for little money. Do this before you do anything else, not multiple things at once. Installed in a f-800 5.9l industrial Cummins motor tow truck that used to top out about 65. Did 3k kit leave out small spring, now 75 with ease. Will recommend to others and would buy again if or when we have another truck with this 5.9l motor.

This spring set helped bumping up my 12 valve top rpms from 2200 to 3000 (smallest spring not installed). Also the gas pedal has a quicker response, love this mod!

Kit has everything you need to install in your P-pump except instructions. You can use another kit's directions from online. Remove all shims and spacers except for the outermost spring and largest shim. Drop in as a stack. Can be configured for 3k or 4k. You'll probably need to reset your idle after installing this kit. You may also have to adjust the "fast idle" screw to get access to the RPMs above 2500.
