High Mileage Reports - With Stock Cp4

I'm looking to hear from who out there has some higher miles and have not had any issues with their Cp4?


I've currently got 32,000 on my '16, but im tossing around the idea of trading it in next year before the new HD comes out, and getting an '18 with the LP5. I'm just trying to decide on if I want to stick with the grenade under the hood or trade up to the LP5. A Cp3 swap isn't out of the question either, but I'm hard pressed to put that kind of money into an already expensive truck just to make it more reliable.

Just looking to see who has taken the gamble and beat the house!

Just traded my 12' with 102,000 miles for an 18'. It made 460rwhp and 900tqs with a single Kennedy lift pump and never missed a beat, that truck hauled ass. I also ran stanadyne additives year round. I traded it in because I wanted a new truck, otherwise im confident that truck would have made it a long time without any mechanical issues. I did all the mods at 5k miles so it lasted almost 100k basically maxed out. Don't let the CP4 scare you off, if you like your truck just keep rockin it.

Wow that is awesome for miles, what is your normal routine for maintenance? Anything different than the normal items?

Stock 2013, 101,000 miles. No issues. I guess that's not very high though.

150k+ 2012. Running fine. Did install a Kennedy single with two filter heads a year ago tho. I also use stanadyne performance formula every tank.



🤘 Kennedy fuel system support hardware, CCM front Diff Drop, some LEDs to make night into day, got some big ol 20's and wide ass tires and a nice display to show me what's up under the hood-
