I'll have to look at mine... I never even noticed any Schrader valves. Any pressure would be fluid wouldn't it?
I didn't have any leaks anywhere using the supplied thread sealer.

Only beefs- Teflon tape or sealer, the instructions I received did not include mention of cure time (or did it say look at bottle?) and the bottle didn’t say. My first attempt at setup= leaks. Search YouTube, several videos mention this and apparently 24 hr cure. Then find the manufacturer has a video ( but not the main set up instructional video) which states cure time is 24 hrs (or whatever). Not reasonable imho to expect me to find their separate video with this info; add a note to the instruction or make it painfully clear in every setup video.
Also, the air cylinder Schrader (sp?) valves, not a single air pressure gauge that I own fit well to get an easy accurate reading.

Both good points.

My system came with the liquid sealer but the instructions were written for tape, no mention of sealer at all.

The air cylinders are so small they're finicky. They're so small that small additions or removal of air volume results in big changes in pressure. I used an air compressor but it may be better to use a hand pump, or turn the pressure way down on the compressor.

Whew...my memory is shot.. I had to go back and look at the manual as I didn't recall the air valve...but there it is and I checked it off of the checklist.
Carry on...

I've never seen these, looks nice but really limits access to sides or am I missing something?

[Greg Reid]

It limits access FROM the sides but really only blocks the rocker panel areas. You just have to use a creeper or whatever to get under the car from the front or rear.
Take another look at jhein's photo in post #1. What can he not get to?

[misterp266]

I prefer a good old bumper Jack! Easy and super safe too!



I guess if you have a big shop, getting access from the front or rear of the car is fine but with limited space, I need to get under the car from the side. I like the block idea that Gach posted a link to. Better than the usual stacks that most people make.

[Greg Reid]

Not trying to talk you into it but look back at my photo in post #12... I don't have a big workspace!...lol. I use one half of a two car garage.
If I'm working on the rear, I nose in, if I'm working on the front, I back in. Also, in that photo I think I only have the lift half up. Hard to tell in the photo but if it's all the way up I can move easily from one end of the car the other without feeling claustrophobic. If the tire is removed I can also easily get in from the side, behind or ahead of the jack.
For the rear end change I was doing it was easier for me to have it a little closer at that stage of the job.

Looks like all of the jacks stands did what they were designed to do….l

Anyone with a lick of common sense can see those wimpy jack stands shouldn’t be used under a big truck. The the size of the stands are completely inadequate, a pair of 6 ton stands are stable enough to handle that truck, forget those 3 ton stands.

I fabricated an entire 3” exhaust system on my ‘64 GTO using 4 of the Harbor Freight 6 ton stands at their full extension, this was 30 years ago. Perfectly safe and stable for the job I was doing, I always shake the car side to side to check.

Only an idiot uses little bitty jack stands under a huge vehicle, the weight rating means nothing if the stands are just physically too small at the base to have any kind of stability.

Useless video.

That guy is too anal, drives me crazy ! Just get to the point already.

Sounds remarkably like a design failure, that should generate a Government-mandated and very expensive recall to correct, with payouts for folks already harmed by this product defect.

If only the US Government had a watchdog agency looking out for consumers, instead of lapdog agencies looking out for Big Business.

My low-rise lift has ONE safety-catch, zero problems with one side dropping while the other side stays in place.

I think it's pure operator error, not a defect. Anything that lifts heavy things up is dangerous. Anyone can buy a product and misuse it for a bad outcome. Jacks, jack stands, anything. A person can buy a car that goes faster than they can handle too. Not a defect.

[OZZIEVILLE 67 2 door]

I can't wait till I move to a shed with a hoist or 2.
Current project,
On stands with house bricks to add a little height.
I gotta make do with what I got , I'm confident it's safe as it's been in the carport for 3 weeks now.
I do like the quick lift .
Need to do some research on that lift

If one person had that problem, it'd be operator error.

When multiple people have that error, it's the twit designing the product who didn't think through how folks would fail to release TWO totally-independent safety catches permitting disasterous results. The product should be designed with only one safety catch, or both safety catches get released with one handle or lever, or there's an interlock on the "down" button so it won't go down with one catch still engaged.

This is LAZY, SLOPPY, CARELESS, BRAINLESS engineering of a product intended for D-I-Y (People of the Land. The Common Clay. You know...Morons.) The manufacturer must be punished.

Well, I guess someone could sue them and see what happens.

[TedRamAirII]

I usually go to the end, that's where the results of the testing are, and choose the best for the money.

[Greg Reid]

The people who safely use jack stands are smarter than the people who use the Quickjack I guess. They have to securely pin FOUR individual units.

[dataway]

When I use my Quick Jack I put a jack stand inside the QJ just in case. Fits between the rails and up against the top plate.

[Sirrotica]

I just laid out the 2 sections I need to cut out to reinforce my floor for my 12,000 lb. 2 post lift. (needs 5 inches of concrete, I have only 3) It should be a month after the concrete cures I'll have a full fledged operational 2 post lift in my garage..........

I will do the same simply because there's no good reason not to. Backup is never a bad idea.

But I still think that the QJ locking mechanism is very secure and main risk is the raising and lowering process, and most all of that risk is user error.
