S&S Diesel Motorsport® Gen2.1 CP4.2 Disaster Prevention Kit Compatible with 2011+ 6.7 Powerstroke (CP4-6.7F-BP-G2.1)

Absolutely a great kit. Not an easy install but can be done by following the instructions. Love the details and pictures to make sure you understand where everything goes. Took about 4 hrs but took my time checking everything in between. Anyone who has a 6.7 needs this. Very cheap insurance for preventing the major damage that could happen.

Takes a bit to install but the instructions and YouTube videos are on point. Adds peace of mind for my 6.7 that just turned 200k. Very, very well put together kit with super quality parts.

So far so good. Install is pretty straight forward. Instructions provided in box are clear, but S&S could take the time to create more specifics for the different years. My truck is a 2017 6.7 power stroke and there is a small portion where the instructions lack, videos don’t cover it, so it just takes know how. No fuel pressure issues and no leaks after a few weeks and added peace of mind.

Have no real miles on it yet but the kit is well designed. Former ASE certified tech i still do all my own work. Kit is relatively simple to install just alot has to come apart to do it. If you not mechanically inclined take it somewhere as you're messing with alot of the top end here and a number of things can go wrong. I initially purchased the cheaper $100 no name kit on here but once it came in I realized the lines supllied were feom china and rated for hydraulic/brake fluid. While it may have been fine i didnt wanna take a change with the diesel especially the bio blend erroding the line. So i opted to spend the money for this kit and im glad i did. I changed both my fuel filters an ended up getting no fuel to the topside filter. After digging in I realized it was an error on my part. I didn't bottom out the lift pump filter and it was pulling air. If you change the lift pump filter on the rail lube the o ring with light oil or diesel fuel and tighten it till you hit the mechanical lock. If you have to force it hard something is wrong. Mine got tigh and I though I bottomed out and it gave me issues. That has nothing to do with the kit just a tip for anyone who may run into that changing the rail filter. Kit looks great, have no loss of power just be sure to check the FCDM for metal shavings in the screen. If you have them you pump is done and might as well upgrade since its all apart. Also for those of us who have the 11-14 powerstroke that has the ceramic bearings. You will literally be at the intake of the turbo when doing this. This is a good time to check the play on the wheel. A little sided to side play is normal as the oil pressure will take that play out but there should be no in out play when you push pull the wheel. Also look at the turbo housing. When the bearings go bad it will allow the turbo wheel to touch to housing and gouge it. That's the sound you hear when the bearing fail. THANKS S&S

Installed on a customers truck, planning to install on one of our fleet trucks next. S&S is a good company and the instructions are very clear and detailed. Everything fits pretty well and looks like it's supposed to be there when the install is complete. Can't ask much more.

Product seems good,easy install

I got this after a friend of mine recommended it based on the faulty CP4’s that the 6.7L’s have. A month later I’m driving down the highway and my truck starts spraying fuel. My fuel temp sensor seemed to have failed and one of the rail sensors in this kit melted…ya that fuel was HOT, fortunately I didn’t catch my truck on fire. I emailed their support team explaining the situation asking if I could get a new piece of theirs that had melted due to the temp failure. They said yes, and mailed one for free immediately. They also recommended I check my filter on their kit bc they had seen that failure being related to a CP4 failure also. I did, and sure enough metal shavings all in it, the CP4 had failed, the disaster prevention kit saved the day.This saved me $1000’s having this kit. Now I need a new fuel pump so I bought the DCR conversion from them because of the incredible customer service and quality of their parts. I just had it installed. Truck runs great again!

Great, well built product. Make sure to set aside an entire weekend to complete the project if you're a newbie. Three trips to Auto Zone, blood, sweat, and tears, finally got it installed with no leaks or error codes. Be sure to watch the SSFuels YouTube video with Ian going step by step for the install.
