Floor Jacks

Just Be Careful.
I have 4 hydraulic jacks, all from Harbor Freight. The light weight aluminum short arm jack is fine IF just jacking up a short distance to say remove a tire. BUT if jacking near it's max lift as noted in the pic below it has to move "into" the center of the car 2.6 inches to keep the jack saddle under the jack pad (you do need jack pads to lift a Vette.)
After having the short arm jack slip, when it did not move in enough on my concrete driveway, I bought a long arm jack. It weights ~95 lbs and although for the same lift height as the short arm jack it only has to move in 1.2 inches but is so heavy it was not rolling even on my tiled floor garage as the Vette was lifted! That means the jack saddle must slip over the jack pad. The jack saddle recess is so shallow it is not enough to provide any help from the jack pad to "pull it into the center" to keep the saddle under the jack pad! As noted in pic, I welded a steel lip onto the jack saddle that captures the jack pad! Now it cannot slip off and pulls the jack into the Vette center. I still watch carefully as I lift the Vette to see that, whichever jack(s) I am using, the saddle remains under the jack pad as it is raised to assure it has not slipped.
I'd sure check to see where the jack was made as most are produced in China. I would not pay a lot more for one made in the same factory as those where Harbor Freight get theirs! Recall when we toured the huge Harbor Freight warehouse in Dillion SC (it is 1 million square feet and is one of only two, the other in CA) with our ASME local section, one of our members asked the facility manger who conducted the tour if they sell any products from Black & Decker etc. He said, "I see those brands being made in the same factories making ours when I visit China!"

The Best of Corvette for Corvette Enthusiasts
Bought my 1st large Harbor Freight hydraulic jack when I built my Street Rod in 2000! Has always worked great. At that time there were no Harbor Freight stores in our area so it was shipped free as was my Engine Lift etc from CA to SC! For home use can't beat their products/prices!Side Bar:
Never owned a clamp-on current meter because they were typically over $100. Recently bought one from Harbor Freight for ~$13 (with 20% off coupon) and solved a tripping electrical breaker problem. Could watch as I added the lights, appliances and fountain pump to that line and see the amperage increase matching the appliance amperage data plate and light wattage! All well under the max 20 amp breaker. Found it was an intermittent short in a buried outdoor power line when it rained!
My point is, their prices are so low they have created sales of items I would not have purchased!
Have noticed they are now offering some upgraded products, such as engine powered generators. They are publishing comparisons with Honda generators, for example. Something I am very familiar with, welders, they have added an upscale product line called Vulcan. Compared to the very cheap "Chicago Electric" brands they still offer, the Vulcan welders have industrial capacities and over twice the price. But the inverter based welders are very well built and about half the price of Miller, Lincoln etc. They show comparisons with Lincoln! They recently doubled the size of the warehouse (one of only two in the US) that is located near where I live!

BUT,,, I've got a two post lift in my garage, so anything that is getting worked on is there.. But to rotate a tire, or clean a wheel? The light weight, easy to move jack is the go too...
If I had to put something on jack stands, get the big jack. (for all the reasons listed above, but that's why I installed the lift... I'm NEVER, EVER, working under a car on jack stands again...)

Anyway, thanks for the responses!

I use "Stanchions" for the back wheels. Made the ones shown and also have four 12 inch high commercial ones I used when building my street rod but takes a several step jacking proceedre to use those. Then for the front, I use two jacks and put jack stands under the approved lift locations on the front cross member. I lift both the front and rear with two jack pads alternating both sides a few times so it stays level. In the front I lower lower the jacks on the jack stands. BUT the jacks are left touching the jack pads as a safety precaution. Belt and suspenders -but safe!
FWIW for those without the space or who don't want to invest in a lift.

What the ramps are good for is temporarily getting the car high enough to reach the cross member jacking locations. This allows you to lift in stages - go up with a set of jacks (one per side) on pucks, place (front) wheels onto ramps, reposition jack and go up again using the cross member, then place your jack stands as recommended.
Watching all the videos for the Quick Jack it seems like the BEST solution out there. Rennstands are a close second, but you need a really low profile jack and low profile pucks since the stands minimum starting height is 2". The distance to my pucks (Z51 stock ride height) is about 5.25" which means you need a sub 3" jack - like HF grey one.
Believe I paid around $109 for it.
