Take a look here, this thread should have all the info you need:

Stock size pistons are available.

It means the bores are still good, so I can just replace the pistons and not have to pull the motor or take the bottom end apart. I will probably end up wishing I pulled the motor, but it should be as simple as raise the motor, drop the pan, take the rods loose, and slide them out the top...

I assume it’s the 58748932?

Thanks for the insight. Agreed, this is why I was going to send them off to have them tested/cleaned/rebuilt if necessary.

It's supposed to be a stock+50hp tune, and obviously there are good and bad tunes, and room for improvement on stock tuning, but there are also practical limits to how much difference you can make without increasing temperature and pressure. At 11k pounds, the 5500 is still way quicker than my...

Honestly I hadn't even thought of that. I assumed they were $300-400 each, so the idea of adding another $2k to the rebuild didn't seem necessary, but I see places online with them for $150-200. Adding a grand for piece of mind is something I can stomach. Any reason to not go back with stock?

All I mean by that is it's not a stock tune, so it's going to build more pressure and more heat to build power so inevitably it is more likely to cause failure. Definitely plan to have the injectors tested. Anyone know of a place near Charlotte, NC, or if not, a good place to send them off to?

No idea. Truck was tuned and deleted when I got it, and has spent most of its life with 15k pounds of equipment behind it or 6-10k pounds in the bed or both. I can’t tell you how many times I’ve run the grades going up the NC mountains at full throttle and grossing 30k pounds. While I’m sure...

$500/ea from Ram. I do need to see if they are significantly cheaper from Cummins. In my fog of frustration I hadn’t thought about checking Cummins yet. I assume the Cab and Chassis pistons are somehow different and more expensive and not as good. :rolleyes:

In case anyone else in the future finds this thread via Google search like I did, I had the exact same symptoms, and it also ended up being a hole in a piston, #1 in my case. My truck is a 2017 5500, had 197,000 miles, and ran about 100,000 miles of that deleted. I was towing 15,000 pounds of...

Correct. My truck is a 2019 with 2019 ECU. It has 23+ mirrors and 23+ door module, and the mirrors STILL auto-fold even though its a 2019 ECU.

There was a harness, it is plugged in, and the lights are working (though I just noticed it’s in the wrong place, must have gotten bumped around when I was installing the seats haha) On the first step with Alfa, do you recall if you used Type 1 or Type 3? Both are pictured. Mine was...

Just did all the changes with Alfa but no lights on the switches and I assume no heat function. 1. My truck had a jump seat but not the full length center console. All of the USB functions and everything else work via the jump seat harness, but maybe the heated rear seats are not prewired on...

Good deal. Yes, truck was a Laramie like yours with heated/cooled front, but no heated rears. I've switched it over to Longhorn seats.

Awesome! Did you have to make any hardware changes such as the harness mentioned a few posts above, or was it all just in Alfa?

Yes, I have and use AlfaOBD.

@RamRod987654321 did you get this sorted out? I just swapped my Laramie seats for Longhorn seats and would like to get the heated rears working.

While we’re at it, is there a version with cameras but without the rear spotlights? They take away about 1.5” of convex mirror which would be much more useful to me than the spotlights.

You’re telling me the engineers and assemblers at the factory didn’t just cut some extra material away like people on this forum did?!?!? :D
