That's what I thought. Just second guessing myself regarding vibrations while it's idling and up in the air.
I think it should be fine..
Let me know if others have any concerns with this.
Thank you.

Not a problem. When I installed my exhaust system I started the car and then went under it to check for leaks. The QJ system is VERY stable.

I'm the OP of this thread and I still love my QJ system.

Well, my Z has been in the air for a couple months now as we are in winter and it has been raining non stop..
I start the Z every couple of weeks for 20 minutes to get fluids running and up to temp. No issues while it's up on the Quick Jacks!

This has been a really helpful thread - my dad just built a new outbuilding/garage and has been toying around with the idea of getting a hydraulic lift, and a QuickJack is one of the options he's been throwing around. I was able to pass on some of the info you guys have listed.
The portability is a big selling point - he doesn't want to have one of the bays solely dedicated to a lift. As someone who will likely (read: definitely) be mooching the use of it, I also like that it doesn't have crossmembers underneath (from what I can see) so I can use a creeper to access the underside of the car.

Good stuff. Thanks all for the pics and great information.

Yes, you can use a low profile creeper with the QuickJack, as long as you don't have too large of a beer belly!

On this system are you still putting jack stands under it as a back up so you dont get squashed if it fails? Just wondering if there is a fail safe of some sort...

Yes there are safety locks at 2 points

To the OP, how's the unit holding up? Any issues?

Connections leak

Leak from where they are screwed on or quick release. I suppose if the former then redoing the fitting with better teflon tape might help. If it leaks where the two quick release pieces join then a better quality fitting might help. Although for the $$ charged you'd think they come with premium fittings.

My connections have not leaked.
I'm kind of lost where anyone brought up leaking anyway.

The connections are quite good actually.

Leak at the quick connects

Sad to say mine leaks also but not at the quick connects but at the resivor box after just 2 uses :icon14:

Can't read the whole thread but does anybody have an issue with the down function on this jack system. I went to work on the car today, but couldn't install the hose on power unit. It appears like there's residual pressure in power unit and hitting the down button doesn't relieve the pressure. Any ideas would greatly be appreciated. :)

Are you sure the residual is in the power unit?
It might be in the hose.
Remember, there’s still fluid in the lines.
I’ve had a few times where I’ve had to push pretty hard, but finally got connected.
