Have you examined a body mount puck enough to know how the bolt gets to torque? That is critical to understanding why body mount sliders are a bad idea
Sigh. No I haven't. But I'm not interested in a trip to the dentist. And thus far this is like pulling teeth.

There are so many of these type of threads. The slider guide thread has some good info and 30 pages on sliders.
tlThe second link i found just searching body mount sliders but looking through it answers some of your questions.
Happy reading.

I wasn't asking to be socratic...but understanding that is the key to understanding the rest. If you look at a body mount, you'll notice that there are steel sleeves and washers bonded to the rubber. When assembled properly, the steel mates to the steel and gives the bolts something rigid to build tension against. That is the ONLY way to generate enough friction in the threads to hold the bolt in assembly and keep it tight.
Incidentally, this is also the same reason JKS body mounts won't work long term. If you've ever installed a set, you understand not being able to hit torque with the body mount fastener...Not only that, they continue to creep over time and you loose bolt tension and the body is no longer supported evenly.
It's ok if you were.
For some reason, that turns people off...Natural Curiousity is about as common as common sense anymore.
For some reason, the elegant simplicity of the TJ body mounts really seem to escape folks and even folks who design parts. This is a cut away of the TJ body mount. When the bolt is tightened, the mushroom stem bottoms out inside the lower which slightly compresses the two rubber elements. The upper element is solid for support, the lower is hollow with a skirt to slow down uplift.
A lot of designers fail to understand how they work or even how they are installed on the rig. Some of them live in a recess in the torque box so when you stick the bottom of the rail on top of them, they are considerably more displaced than just the thickness of the rail.
As a consequence, that creates very uneven loading of the mounts and in some cases, most cases, can and does lift the body off of the other mounts.
I’ve been following this thread as I’ve been a little confused by “body mount” sliders as it seems pretty much all of them mount to the body, including the OEM sliders rather then the frame. I think i understand now, a body mounted slider is one which requires removal of the bolts which hold the body down, then sliding the slider between the mount and body and reattaching the bolt.
If you aren't going to use them other then a step bolt them to the frame. Like old school truck "tube rockers".
If you are going to use them - get a set of Savvys.

What is being described is sliders that attach to the body mounts and also bolt to the body. The body mounts are designed to support and isolate the body from the frame and suspension thus reducing NVH ( Noise, Vibration, Harshness). When sliders are installed that bolt to the body below the door and then attach to the body mounts underneath the vehicle this creates a solid or semi solid connection between the body and the frame. When the slider mounts with the body mount the body mount cannot be torqued to properly compress the body mount to function as designed. This will increase noise, & vibration up into the passenger compartment due to the mount not being compressed properly as it was designed.

Never seen salty roads. I grew up in Iowa where everything rotted out within a few years. I’m still amazed at how many ford and Chevy trucks from the 80’s and 90’s are still on the roads down here.
I live in Iowa. I'll be coming to get your rust free trucks!!
