Yeah but that has the upgraded rear cans for the planned armor package, is light as hell (bare chassis as delivered), and is a 6x6 with twice as many brakes in the back. The 6x6 trucks, especially when running light, have tremendously strong brakes being they aren't *that* much heavier when not...

Well. Given his truck is 24k lbs, and my truck (M1079 A1R) is 21,500 lbs..... I have essentially the same setup he has now and I have no issues with my rear brakes locking up - indeed I have never been able to get my ABS to activate. He is so close to the GVRW and doesn't plan to ever not have a...

Yeah it just has one in and one out. There's a T on the on the passenger side right at the valve. Apparently even though it was fully in the "up" position, deleting the valve made a HUGE difference. I'll let him post his findings.

Ah I see! So the LSV effectively just reduces braking when the truck is light while the ABS tackles the problem from the other direction - preventing wheels from locking up when the truck is light. Got it. I'll pass that along and he can decide what to do and how to tune it.

Working with a member on his A0 brakes. Considering deleting the Load Sensing Valve since the A1+ trucks including my A1R don't use it and seemingly have no issues without it. Here's the A0 pneumatic diagram and the A1R pneumatic diagram. It would appear they simply deleted it. The later...

Correct. It's a matter of preference really. I mentioned the factory controller because it wouldn't care about being wet in a high-water rescue environment, etc. You can read a bit about them and what you can do with them here on this thread...

I think every day was a Friday at the S&S facility. Chrysler got all the news reporters filming their guys with brewskies and J's on lunch and before their shifts and diverted the attention for everyone else. I've found SO MANY wiring deficiencies with these trucks (mine, friends, and even...

Never heard of or seen a single report of that type of failure. Every one of these trucks I have dealt with has had amazingly clean coolant with little to no corrosion despite probably never being changed - My guess on this is that the cooling system being double the normal size (they basically...

Are you going to run ECO hubs? If so I wouldn't bother. The cooling system on our trucks is sized for twice as much engine at the "normal" RPM range that ECO hubs run the engine. For my clutch fan to engage on my 370 HP C7 M1079 (21,500 lbs) It has to be at least 75+ degrees outside and I have...

It takes literally a couple minutes to find, cut and insulate the 1911 wire to the controller and now it will inflate them to 81 psi for you. 🤷‍♂️ Just my personal opinion. But I have my truck setup to run cargo or bobtail pressure at the flip of a switch. If the CTIS valve will work with the...

The CTIS can be set to 81 psi by switching the 1911 wire to the controller from power to open (cut the wire or install a switch). Here's my thread on how to change the CTIS settings without programming. You can do even more with the Dana software and an RP1210 adapter/laptop...

The factory Dana controller IS water proof. And also programmable. It also seems to a little more tolerant of wiring harness short circuits. Buddy of mine bricked his Arduino due to his truck developing a wiring harness fault. Dana controller survived and was able to diagnose and report a fault...

They are a known failure point so I would replace both. The new ones don't stack I don't think. The MTV power divider is only used when you select MODE on the Allison control panel.

I will add that being an FD truck - the newer style cartridge dryer is more likely to actually BE serviced since it only takes 5 minutes and a new cartridge vs the old style that you have to essentially remove from the truck and spend at least an hour servicing assuming you have a new bag of...

Curious as to why you haven't considered a 24v quad-mount (pad mount) alternator like @MatthewWBailey used on his build? Reportedly a toddler could bolt it up. No modifications required...... https://www.ebay.com/itm/276496175581 His post...

First of all - upgrade your air dryers to the newer style Haldex PURest dryer and service them every 6 months or you will be buying new air compressors like they are going out of style. Second - you don't service those valves you just replace them. They are inexpensive Haldex parts. There are...

How does it ride though? I was concerned after looking into weights and valving that nothing seems to be even close to what these trucks require. What I noticed with the stock FMTV shocks I've played with was that they don't rebound on their own and can be moved relatively easily if you move...

They shouldn't open with a regulated supply at 55 psi going into their control line and if they are venting they would be venting *tire* air not air from your compressor. That should inflate the tires (if they are low) to that pressure and stop - if they are higher than 55 the air from all the...

Did you inspect the main cab ground behind the grill yet? There's really no point in troubleshooting weird behavior till you clean and inspect every connection. Then if you still have problems start doing voltage drop tests. These trucks were built with REALLY SHITTY ground and power connection...

Military pays $235 and some change as of Jan '24 for that part. 🤷‍♂️
