CAC Turbo boot
I have experienced a couple of instances of the boot between the turbo and the metal CAC tube that connects to the Charge Air Cooler, popping off during higher boost conditions. I know that the inherent issues caused by the crank case ventilation of the 6.0 liter engine results in the deterioration of the boot due to heat and chemical reactions that is caused by the oil that penetrates the boots eventually leading to the need to replace the boot.
I have ordered the Riff Raff replacement boot and clamps to install on my truck. In addition, I am aware that many of you on this site recommend using hair spray on the inside surface of the new boot to help the boot stay in place once installed. I also know that there is a Ford product that can be used for this purpose as well, but I have spent some time searching the site without being able find any discussion regrading this topic. Does anyone know what the Ford part # is for the substance? Thanks in advance.

Brake kleen, hair spray and let it set up (dry). Don't be scared to tighten the clamps PAST the torque specs....they won't break, be smart about how tight you go obviously. Make sure the boots sit in the dimple groove on the components that have it.
You don't need any other snake oil for this setup. Riff Raff boots are high quality, and I personally think the OEM band clamps are the best, but I am certain what you bought will work just fine. Unless you are pushing 40+ lbs of boost you should be fine with the set up. Check your boost and make certain your turbo is functioning normally, within range for your engine setup.
Good Luck.

Do the Riff Raff boots have the internal bead? Last time I checked they did not.
I use these https://www.thoroughbreddiesel.com/1407006/ never used hairspray.

Same as @JoeBlow you won’t need hairspray with quality boots like @Riffraff Diesel and single clamped is fine. For at least the last 5 years or maybe more they have the internal rib for the turbo cac pipe. I have run several sets over the last 15 years with great success. Just make sure the surface of the pipe is clean and then torque them nice and tight. I see over 45psi on my Excursion with no issues of grip.

INo the Riff Raff boot does not have a bead inside.
I have fabricated a steel strap that connects between the altenator and the metal CAC tube which prevents that tube from moving (towards the passenger side of the truck), keeping that tube and the boot from becoming disconnected
as a preventative measure.

That boot is the biggest offender when soaked in oil.
The Riff Raff boots are thick and don't flop around like the cheap/thin OEM boot.
That tube you now made solid is meant to "move" with engine torque and remain flexible because it is connected to a solid mounted IC.
Not the best of ideas to branch it to the alternator.

You are correct, to a point. The rigid CAC tube is flexible at two points, the upper and lower boot.
You've now eliminated one flex point, is the only point I am making.
It's your truck my friend, do as you wish.
