Corvette models have required the J-43625 Lift Pad Adapters to properly lift the vehicle since the C5 generation debuted in 1997. The lift pad adapters help ensure proper vehicle weight distribution and must be installed in the correct locations when lifting the vehicle. Failure to use the lift pad adapters correctly may lead to the vehicle slipping or falling off the lift or jack.
TIP: When major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from where the components are being removed and strap the vehicle to the hoist.
Frame Contact Hoist
For the 2020 Corvette Stingray, install the J-43625 Lift Pad Adapters into the front (Fig. 6) and rear frame rail slots. (Fig. 7) Rotate each adapter 90 degrees. Center the hoist pad under the lift pad adapter.

The lift pad adapters also should be used in the frame rail slots when using service jacks.
Ground Effects
Depending on the ground effects installed on a vehicle, it may be necessary to put the vehicle onto gradual incline ramps to allow the lift arms to fit under the vehicle. (Fig. 8)
I would recommend having a set of the jacking pucks - could save some damage.
I agree even at a Dealer! Assures the lift arms on a post lift are NOT placed in the wrong area! With 60% of the car's weight on the rear, easy to do! That "some damage" could be a catastrophe!
This Dealer didn't lift properly. Not hard to do.
Dealer Tech can easily put lift arm in wrong rear location. Jack pad helps assure C8 is lifted on frame in the correct location. Would not bring a C8 to dealer or tire Tech without bringing 4 jack pads and insisting they be used. Have a great Corvette Tech and my C8 PDI is first C8 he saw. He had not seen this pic and he agreed jack pads assure his lift arms are in the right place. Pleased I bring them. If I have to bring to Discount Tire etc will spend the time to install my Reverse Logic Pads temporally as can't be sure they will lift properly! PS: Have jacked my C8 to install low dust brake pads, side skirts and AC Condenser mesh. Not easy to find the oval frame slots. Had my head on the floor and used a flashlight. Have seen techs (not the one I use) kick the lift arms with their foot to put under a car! Understanding the large area that looks proper in the rear to place lift arm BUT is OUTSIDE THE FRAME would not be hard to do!

Reason: outside the frame
How thick should the pucks be? Most mounted pucks are only ~9/16" thick. Is this adequate?
If you don't have side skirts should be OK. Put a level on the 9/16 inch and you would see it clears the rocker panels. In my case, with side skirts my 1 inch high jack pads work fine with good clearance to the skirts when using my long reach, long arm jack. If I were to use my short arm jack (10 inch arm) would use my 2 inch high jack pads.
These can
be mounted permanently. Dewhel jack pads. $39.99 for 4.
I use these & they are perfect for the job. Easy to see from the bottom, not too thick that they might catch on something, and they're always there. If you have to have your beloved C8 towed or pulled onto a flatbed, it will be easy to show the driver where to jack up the rear to put the wheels onto coasters. Now don't forget the Tow Hook to be able to drag it onto the truck.
I ordered four jacking pucks that can be used temporarily or permanently with the intention of permanently mounting them to the frame. I was also intending to buy tow eyes since the pucks go into the tow slots in the frame. But, in reading the owner's manual, it says "Do not use the tow eye to pull the vehicle from snow, mud, or sand." So, if I run it off into a ditch, I'd have to carry an Allen wrench for the tow truck driver to remove the pucks. So, now I'm pierced on the horns of a dilemma. Do I mount the pucks and, if I'm off if I'm in ditch, hope the tow truck driver takes the pucks off and doesn't ****** it up from somewhere else? Or, carry the pucks unmounted and hope the guy using the lift remembers to put the pucks in?

Carry the Allen wrench and remove the pucks if you find yourself in a ditch. Problem solved.

Hmm, if your in a "ditch" how do you expect the tow truck operator to reach in and even see the GM oval slots?? Have jacked mine up a number of times (week one to install low dust brake pads, installing my splitter, installing side skirts) and each time had to lay on the ground with my head on the garage floor to locate them! Especially the rear, which are back some distance from the car side.
Frankly most tow truck operators will just use the hooks they carry and attach to whatever lower "A" Arm members they can reach! IF I'm in a ditch, no doubt have other damage and my screw-in toe hook eye will probably work fine and cause little extra damage. I keep the one I bought for my 2017 Grand Sport in the tool bag in my Frunk.
Suggest there are bigger life dilemmas to worry about!
