19" vs. 31" height - and USA made for $60 more. No comparison IMO.

I wouldn't trust anything from HF to hold up a 20k lb truck. The military uses these for FMTV's: https://www.ccmilitary.com/products/heavy-duty-jack-stand-7-ton

You just need the alternator and bracket and longer serpentine belt and it will bolt on - very easy - takes less than an hour typically. I am working on getting a few of the alternator brackets and I do have a tested 2016 model 260a for sale so I might be able to set you up with a swap kit.

A few years ago a bunch of crew protection cabs showed up at auction - before the FMTV's were popular and being seen regularly at the auction. The HIMARS trucks were some of the first to be upgraded to the A1P2 armored cab specs and so these first gen cabs were removed and auctioned. The crew...

Yes. The CTIS controller has overspeed warning and protection. If you exceed it's programmed speed limit in each mode it will first warn you with a CTIS Overspeed flashing light. If you continue to ignore the warning it will automatically inflate to the next pressure mode. You can change the...

I have one of the 24v Chinese mini-splits mounted to the Environmental Control Unit cover plate between the pods on the front of the box. And I mounted a 120v Dometic Cool Cat unit inside the driver's side pod where the ventilation fan used to be (enlarged the opening).

Sure. It's a first generation HIMARS crew protection cab commanders hatch:

A1+ trucks the CTIS get its speed pulse from the CAT computer.

Transmission control unit - these don't like voltage problems. Was your voltage actually high? My truck would go into over-voltage cut-off and on two or three occasions I got an over-voltage warning from my TCU as well. It's the first thing to complain. They are also one of the more problematic...

Seeing as that post was nearly 10 years ago and that member hasn't signed in for 1.5 years I find it unlikely you will get a response. Also these parts are much more available now. For example: https://www.lmtvtrucks.com/AC/index.html

So here is what Allison DOC says in the help files and what options it gives. It looks like you want the "Low Preselects" to shift the RPM down by 150 RPM. Not exactly sure because I haven't tried it and the software selection isn't well coordinated with the help files in terms of...

Ah yes - I missed the smell of ozone and burning insulation! Such an obvious example. Some of the "enthusiast" vehicles I have occasion to work on often have an "interesting" take on wire management, routing, and shall we say..... "best practices and standards" o_O

Some versions of CAT ET will give that complaint but still make the change anyway. Try changing it, acknowledge the error, and then switch away from the settings page and back again. I've run into that a time or two. You switch off the page and back again and the setting was programmed in spite...

Well - I can definitely smell brakes being worked hard or dragging, clutches being slipped, belts dragging over seized pulleys, and often coolant and oil leaks as well. Sometimes before I can see evidence on the ground. Hot grease and fluids being flung onto the exhaust from driveshafts makes a...

I meant how the engine manufacturer (CAT) intended for the cruise control / exhaust brake to function based on the programming options. Obviously the truck manufacturer never intended any of these systems to integrate. The cruise control is nice for longer jaunts where you can get out on the...

Not argueing with the CC integration. I setup the CAT ECM to integrate the cruise and exhaust brake when I enable cruise control as well. That works as designed and as programmed by CAT. I have no issue with that. I get what you are complaining about - higher speed when the cruise control...

I don't think you'll get any significant braking effect in 5th or 6th gear unless you are going REALLY fast. And globally limiting it to 5th will mean you don't get any braking effect at medium speeds where it was only in 5th starting downhill. I was at the grocery store last night and on the...

Probably would get more visibility that way. The oil pump discussion applies to all trucks - even more so to the factory hub reduction trucks being they will wear out the flawed pump designs faster.

I would just get it from CAT. Unfortunately there's no way to know which design the third party companies decided to copy and things like the pressure relief valve and spring must be absolutely precisely made. I've seen aftermarket oil pumps for other engines that had sticky pressure relief...
