Jacking point or tie down point?
There has been some debate as to whether the 4 "jacking points" on the frame rails are actually intended as a jacking point or manufactured there as a tie down point for transport. Maybe both uses are intended?I use the front and rear cross members as a jacking point.
Does anyone have reliable information?

They can be used for both, imho - if you need to jack from the side, they are the only place where bare metal is exposed, and also provide you with a handy place to hang a jacking puck.
Also if you are lifting using the typical 4-arm lift, the arms should be placed under the bare metal with a jacking puck installed at each point.

I have a book titled "Corvette C5 Performance Projects 1997-2005". It talks about jacking locations.
"The C5 came from the factory without any visible jacking points. According to the shop manual, the proper points to lift the car with a four-point hoist are the holes that were used to attach the chains on the transporter. These holes are located on the frame rails of the car and in the approxmately the same locations as the jacking points of the C4. But the body of the C5 wraps down the side of the car and rolls under the frame rails. The body actually covers a great deal of the frame rails. There are small cutouts in the plasitc rocker panels for access to these openings, but they help only a little. Most floor jacks (also four point lifts and jack stands) have pads larger than these openings, meaning that the lifting pad too often rests on part of the body, not the steel frame..."
It also goes on to say "It's almost as if GM designed these front and rear crossmenbers as jacking points. While GM recommends other points, it didn't take Corvette owners long to figure out that the corssmembers work really well.

If you are looking for a source, the GM Chassis Service Manual used by dealers shows these points to be lifting points. Also, the company that makes the special tools for GM dealerships (Kent-Moore) sells a version of the jacking pucks with a chain attached to remind the mechanic to remove them before driving. The Kent-Moore part number is J-43625.

If you go to www.awdirect.com and search for T-hook, you will see these nice hooks that go directly into the slots for tie downs.
