My fear of permanently mounting them is they might get caught scraping over something in which case they would likely do more harm than good. I haven't scraped the bottom of my C8 yet but I did manage to almost high center my Shelby coming out of a steep parking lot with a fairly sharp angle of attack getting back on the highway.
The aluminum pucks only protrude ever so slightly below the rocker. If you were to scrape them, you definitely would be scrapping a whole lot more underneath the car than just the pucks.
They are not just "useful", they are critically important. W/O pucks, or some other way to distance the car away from the lift pads, you will CRUSH the bottom of your body panels whenever you lift the car. The aluminum "permanent" built in kind are a little shorter than most people like but do work. The rubber pucks made from hockey pucks provide great clearance, but have to be inserted each time they are to be used...
Of course they are useful if you want to jack the car up yourself, and they are essential for preventing body panel damage even when lifted in a shop. I personally would not ever permanently mount them however. Some do out of concern that a dealer or a shop will lift the car without them, and maybe lift the car at the wrong point. I have my service done at Criswell so I do not worry about that. I keep my pucks in the trunk.
I had mounted the aluminum pucks in permanently on my C7 and plan to on the C8. I used a little blue Loctite on the threads to ensure they stayed put, which they did.

Yes, pucks are definitely useful, however I won't use the 'leave-in' pucks as I know of a C7 and C8 where they became dislodged and knocked chunks out of rocker panels. I don't care whether locktite is used or not just makes no sense to me to leave them in when all you have to do is store removable ones in your frunk and it only takes 60 seconds or less to install them.
If I use a floor jack I just use a hockey puck. Works perfectly. Otherwise the blocks that came with my quickjack work perfectly. No need for permanent picks here

I have a QuickJack and these low profile aluminum pucks do NOT provide enough clearance between the rocker and the QuickJack. Anyone who says they do I’d be happy to send a picture of the gouge in my rocker because they didn’t provide enough clearance.

I have had no problems with the pucks and the quickjack - been up and down on the jack about 5 times now I think.

I find that difficult to believe given the fact the height of the Billet Aluminum Jacking Pucks are only 0.62 of an inch. Yet the QuickJack well that the pucks sit in have a depth of 1 1/4” which means the pucks don’t provide any added value and your C8 is actually lifting /resting on the bottom of the rockers! That’s a mathematical fact.
To increase the clearance between the bottom of the rockers, the Jack pucks and the QuickJack I used a double layer of the Rubber-Cal Maxx Tuff Heavy Duty Mat which sit inside the QuickJack wells.

Read the Quickjack manual - you need to use the rubber spacers for lifting ANY vehicle.

⚠ CAUTION Do not raise a Vehicle on the QuickJack Frames; always use Lift Blocks, Pinch-
Weld Blocks, or SUV and Light Truck Adapters in the Receiver Trays. Raising a
Vehicle on the Frames could damage the Vehicle and/or damage the QuickJack.

I responded to his “mine work fine” comment because he made no reference to using the any Lift Blocks, Pinch- Weld Blocks, etc. and lead readers to believe his aluminum pucks were good on their own.
Bewear side skirts!! more height is needed from the jack lift pad to the car than just the alum pads installed in the holes.
I add 2 inches of heavy rubber mat about 4 inches square to the jack pad to keep everything safe.
Are jacking pucks really usefull ?
