It's going to work just fine. In every application thus far (I've done three including a 24k lb M1088 with 3.07's and the 3126b) the performance is just as good or better than before. Literally every single person that has done this mod has absolutely loved it and has absolutely no plans to go...

Transmission is computer controlled. You will absolutely notice 100% electrical failure as it will result in the truck not moving at all. Your truck will turn into a very heavy air compressor. This goes back to the age old false argument about the A1+ trucks being less reliable because "OH NO...

I would replace the thermostats if they haven't been done - does the fan kick on at 205 degrees? The fan solenoid under the passenger dash kick panel is a known issue. For the tire locking up - pull the spider gear assembly and inspect. Probably should do an annual on the hubs, pack the...

That sucks! I'm not too far from selling the whole mess and leaving the city/suburb also. Too many yuppies sipping wine at the "food" (diarrhea) carts literally around the corner. Not my scene.

Funny enough - I live in a very wealthy suburban area (wasn't when my family moved here with a VA loan in 1978 but 45 years and a lot of luck picking the right place - plus urban/suburban sprawl.....) and all my neighbors love my truck. They see it as a crime deterrent for our neighborhood and...

Not the best video. He doesn't clean the threads in the hub and clearly a bunch of them needed it. Doesn't torque anything (not that this is absolutely necessary for those with enough experience), and doesn't have the wheel off the ground to check the bearing pre-load before slapping on the...

Does your voltage regulator have LED's?

You really should start a new post - your issue is likely that you are losing pressure in the wet tank and the compressor is cycling on and then purging. A reasonable sized leak will dump enough pressure to load the compressor every 30 seconds or so. It only has to drop below 95 psi to cycle the...

I wired my backup and blind spot cameras to running light power so they don't work unless I turn on the parking lights or driving lights. Keeps me from driving away without any lights on.

On my truck the front parking lights only work if you select the Park mode. In service drive they are off and only function as turn signals. In park they illuminate as parking lights with the headlights off and blink brighter with the turn signals. I was under the impression this is how they are...

Two of the installs I have done (mine, and the 3.07 truck belonging to @ckouba) we have done full hub services including replacing the CTIS and wheel hub seals, repacking the inner bearings, and adjusting the bearing pre-load. On @Lostchain's truck we did only the ECO hubs but we did check the...

If the EGT's were higher with the ECO hubs that would manifest as more heat being dumped into the coolant and we would see the cooling system working harder. What we see with the ECO hubs is the cooling system working significantly less. My radiator fan rarely kicks on now. We also are seeing...

The axles still slide out the end of the hub. You just remove the cap and slide them out.

What is to misunderstand exactly? Do you understand the stock reduction hubs? They provide the 2:1 and in conjunction with the 3.90:1 ring and pinion used by all FMTV's this results in a final drive of 7.80:1,,,,, do you understand this? OK. The ECO hubs remove the 2:1 reductions so the final...

Wow. The "kit" from MRO was only $95 a year ago when I ordered one, Wild. Did the trick though for me.

The 3126b and the C7 are almost the same engine. They use essentially the same turbocharger (same size, etc) for both the 275 HP and 330 HP variants. Indeed even the 370 HP C7 used in the M-ATV is the same size - it just has a water cooled CHRA to prevent engine oil coking under extreme...

With computerized fuel injection the ECM is the gatekeeper to all potential upgrades. It regulates boost pressure and supplies the correct amount of fuel to go along with the additional air being delivered - and since these engines have no closed loop fuel control the engine computer has ZERO...

Is there something under your drain plug? My C7 I just stick a 5 gallon bucket under the drain plug and have a second one handy for when the first one is about 2/3 full..... 🤷‍♂️

Awesome! Glad you got it sorted. Now you know how easy it is too!

You should look through my 8 months of troubleshooting to find the source of a similar problem. https://www.steelsoldiers.com/threads/2008-a1r-with-260a-charging-questions.206182/
