Jack Puk
The item that lifts your car that goes in the jack hole. If you have the one that's gold iridated from Mid America could you please measure the dia. part that goes into the jack plate hole! Have new Craftsman jack and before ordering the puk just need to know this dim. to see if it would fit....thanks

I have several different brand hydraulic jacks and the jack puck fits nicely in all of them. The holes in my jacks are about 1.20" in diameter.

The "jack pucks" sold by Mid America are unique in that they have a shaft that fits into the hole of a hydraulic jack, as well as a shaft that fits into the hole in the car's underside. You can't get any safer than that. An earthquake could hit and there's no way the car could ever side off the jack. It's the most positive connection that can be made.

Made for the 318i and is a perfect fit for the C6.
Even with shipping, I paid less than $36 for a set of 4. I put them, and left them in for whenever I might need them.

Got these too, and am happy about the choice.

Someone on this forum said that jacking pucks concentrate the pressure in a fairly small area and can dish the frame "like they do on the C5." So I asked on the C5 Forum if anyone had dished their frame with pucks and got several "yes" answers. Hmmm...
The C6 is pretty new, but can some of you guys put a careful eyeball on the frame and tell us if there is a slight deformation from pucks? Especially, I'd like to know if the BMW jack pads cause the problem, that's what I want to use.

Newbie Corvette owner question….
My C6 doesn’t arrive for a few weeks.
I need to buy a new “low profile” jack.
With the “pucks” installed, how low does the starting point of the floor jack need to be to get under there?
I’ve seen low profile jacks that go down to 3 1/2” or 3 3/4”.
Is that low enough?

if you are attempting to jack the front cross member to raise the front end, the critical low point is the center front air spoiler. Most owners address this problem by driving the front tires onto 2 X 12 ramps to raise the spoiler for clearance, but I found that method to be a PITA for a simple oil change and just raised the car for access from the side. If you are raising the car up on jack stands, you will need to raise the front first...raising the rear first reduces the spoiler clearance even further.

Or do I place the jack under these inserts? I'm sooo confused (i'm a rookie)
Note that your owner's manual tells you to place your jack stands such that they are contacting TWO ribs of the crossmember components...I found this doesn't work so well in practice, because the rib edges aren't at the same height, but it works fair. IMO, it's a good idea to stay off the control arms and avoid contact with the bushings.
