Default Front center jacking point

I need to get my '07 Vette in the air to change the oil/filter. Where is the best place to position the floor jack to lift the front. I can barely see under there. The Owner's manual is little to no help. Thanks.

If your car is lowered it's easier to just lift it on the sides...if it's stock height and you have a low profile jack you can slide it straight under the middle; you'll need just get down there to be sure you're jacking it up on the frame.

When I need to jack my Z06 up to remove the front wheels, I drive them up on a pair of stacked 2 X 12's(one 2 X 12 X 15" long screwed to the top of another 2 X 12 that is 24" long, with the ends of both beveled) so I can get my floor jack under the front of the car and be able to work the handle. I made a crossbeam out of a 2 X 6 with some 5.5" square plywood (1/2" thick) mounted on the ends so only the plywood pads contacted the front crossmember directly under the frame rails. Do not jack the car in the center of the crossmember.

I used this diagram from bugmanweb as a reference and use the pink portion on the front to put my floor jack.

I don't know who "Bugman" is but GM does not approve jacking the car in the center of the crossmembers.

The OP could also look at page 402 of his owners manual where it it shows how to lift the car and where to place the jack.

Floyd - Thanks. Who makes a good low profile floor jack? I appreciate your thoughts.

Joe - Thanks, great idea. I got stuck inside the box. Great imagination.

Love the diagram. Big help. I'll combine that with the 2x6 cross board to support the crossmember. Many thanks.

I saw those locations in the manual, but wanted to get both wheels off the ground to crawl under. Thanks for the link.

wood won't do it. it will flex and although it might appear to be distributing the load, it will be placing all the force on a single point the same as it would with just the jack itself.

I made some jacking crossmembers out of 1/8" square tube, 2"x6", and some hockey pucks. cut them to the correct length for the front and rear (two different sizes) and can now lift my car with ease from the center with one jack without stressing the cradle.

I just bought an awesome one from Costco for like 100 bones! It is super low- super long, and 3tons! I will check the name and update my post- but its red and works great for the vette... slides right under the front easily on non lowered cars!

I'm using a wood 2 X 6 with 1/2" thick plywood at the extreme ends, where they ONLY contact the recommended lifting points. I see maybe a 1/16" defection in the center of the wood beam, which still leaves me with 7/16" clearance to the center of the crossmember. The load is still distributed from the jack to the points of the crossmember that is directly below the front frame rails. The plywood pads are soft enough to allow the ribs of the crossmember to slightly embed themselves to spread the load at the recommended lifting points. Wood works, but if you want to use a steel beam, go ahead.

Does GM say that it's dangerous to jack it there? I would imagine the main reason they don't recommend jacking it there is because of the balance of the car when it's off the ground with the jacking point being in the center.

"Preferred" doesn't mean "only"

Everyone always seems to go through so much trouble in jacking these cars up with pucks, boards, ramps, etc... It's just a car...slide the jack under the frame and jack it up.

I just us the pink spot to get the car high enough so that I can put stands under the puck locations, I don't work on the car without stands in place.

Well of course. No one should EVER work on a car without stands under it.

From my 09 owners manual............................

To help prevent vehicle damage:
"• Be sure to place a block or pad between the
jack and the vehicle.
• Make sure the jack you are using spans at least
two crossmember ribs.
• Lift only in the areas shown in the following
pictures.
"

If you would take the time to read a C6 owners manual, you would see that GM shows you exactly where to lift the car, and it's not in the center of the crossmsmber. "lift only....." means just that. It does not mean that you can lift anywhere else.

I have gone through the owner's manual and was well aware of where they show the lifting points to be.

I find that a lot of time the warnings (on many products) are there to be dummy-proof, and don't necessarily mean that things cannot be done a different way. The C6 is pretty sturdy, so I'm sure it can handle being jacked up on various frame locations.

I hate them dumb *** engineers too. Never met a single one that knew what he was doing. Probably had his four year old daughter do a finite analysis on the crossmember for him. He then just added a couple of hundred extra pounds to the car so the smarter C6 owner could just jack anywhere he wants.

I made the 2x10 (front) and 2x12 (rear) wood ramps to drive up on, but it's almost more of a hassle (car doesn't really like going up them, but I need a bit more room to get my jack under the front).
Now. I just jack from the side with the pucks and slide the ramps under the wheels. From there I can jack on up to jackstand height.
For changing the oil, though, I think you only really need to jack from the left, front puck location. The filter and drain plug are so easy to reach. Then you can drop it to drain.
The corvette is so easy to get to the oil change location. My 300C and Landrover are impossible -- gotta get 'em up high enough to get a creeper under... remove plastic skid plates, etc. = HASSLE.
