Ahhh Yes, the "lock". but are you willing to risk your life on a tiny piece of 1/8" steel held in place with a 1/16" piece of rod holding up close to 5000 pounds. I'm erring on the side of not getting squashed/
Zoom not that I don't agree with you but there are plenty of videos showing them cutting the cylinders while the jack is holding up crazy amounts of weight, that "steel" rod not a steel rod ,it is a boxed steel channel and is a lot stronger than you think, the lock that you flip does not hold up the car it just allows the safety bar to jump the locks when lowering
A Quick Jack is so over engineered that I think it's more operator error I worry about
And you don't think that with the internet if one failed we would not have heard about it?
PS I also put jack stands under mine when I am under it

Dave, you err on the side of safety. I err on the side of safety. I think we're in agreement that everyone should err on the side of safety.
My point is, if setup properly they are over engineered , it's perfectly safe and so is the safety ... you don't see people putting jack's under their 2 post lifts do u , heck an anchor could let loose right .... its all about the operator, how the tool is used and the preventative matenence
Earlier in this long thread I and at least one other owner mentioned that we stored our QJ under our C7s. Later on someone questioned if the heat from the exhaust might damage the hydraulic system. Today I drove the car and upon return I placed a thermometer on top of a QJ air cylinder with the sensor end touching the cylinder. Fifteen minutes later I pulled the thermometer, checked the temp, and to my surprise it showed the same as ambient air in the garage (70°). I think this is because the coolness of the garage floor transfers any heat absorbed by the metal components of the QJ very quickly, thus not allowing them to heat up, acting like a large heat sink. I think this would probably dispel any concerns that heat from C7 would affect the QJ adversely, and it would also be worth pointing out that the C7 has a large heat shield in the center of the car between the exhaust and floor that I'm sure is also a factor.
What's more, one of the QJ videos on Youtube mentions storing them under the car as an option without any mention of heat risks. I've been storing the QJ under the car now for >4 years, so I think I'm confident in the safety of continuing this practice.

Thanks for posting this. I have had a concern about storing under my Vette. I suppose the exhaust cools off way faster than the heat can be absorbed into the QJ.
I have the same issues. I think it will be ok but will check it again before lifting the car completely
so for those of you that got the 5000TL, is it working okay on the C7? I'm looking to get one while Costco has them on sale but want to make sure it will work?

i have the 5000TL they work fine under my C7 they are a bit long so I hit the a bit more than 75% of the lifting pucks, the vette has been up on the lift since Christmas without any issue at all.
I'm thinking the heat may rise and move along the drive train and upward through the various escape routes under the hood, as well as from the rear of the car. As that happens the air around the QJ is replaced by ambient air from the sides.
I've used mine several times now since I bought it in December. Other than taking some extra time to setup and being heavy, it really makes working on the car so much easier. I have been putting my jackstands on the crossmembers of the car but will start putting them on the hinge point on the QJ since that will make it even easier to crawl around under the car.
Will I recoup my money vs jack and jack stands? Doubt it. But it sure is more convenient.

Same here as with my 7000. Will never get my money back but hey, it ain't "Joe's" garage, it's mine !

I love mine and while it's paid for itself (got the 5000 for 1k so keep an eye on sales) while working on my 84, I have yet to use it on my 2019. These are definitely more stable then jack stands. I have a small garage so I store them on a wall using the quickjack wall mounts. You can find those for 30+ at home depot online. 😉
I have been thinking of getting one of these to work on my C6 and C7. Do you still need to use the lifting pucks or can you just use the blocks that come with the Quick Jack?

nope - can use just the blocks. Can use pucks if you want.

I have snap in pucks on my C6 but I believe QJ might be a little easier to set up and use without the pucks.

I also have the snap-in pucks that you don't remove and have been using it with the large QJ blocks. I agree with Ecroy that you don't need pucks, but I think having them in makes it easier to align the QJ blocks when setting up. I haven't tried it, but with so little clearance it would probably be hard to find the spot on the car from which you would align the QJ blocks unless you had the pucks in place as a visual guide.
Oh, sorry I didn't add this before. I have the pucks that are attached to the body (frame) and they are very low profile. They are not the same size as the regular "hockey" puck .
