Jack Rod Stands

i guess you could use a floor jack and a stand, but you certainly would need 4 floor jacks if jacking four corners up...looks like a safety lock for a floor jack, does look like a good idea ..gives a floor jack that extra safety measure

Kind of what I was thinking.. Floor jacks are always a bit scary, the hydraulics can leak at anytime... Plus I like leaving my jack under the vehicle with the jack stands too, so as stated, extra safety.
 
Work? Yes.

And it’s a clever idea. With this between the axle and pad of the jack itself, there is no way the jack will bleed down from hydraulics. It locks the jack completely and safely.

Is it worth the cost?

Well, this only works on one corner, so, for me, I would need another couple of jacks, and several of these, which is a tall order.
 
So what do you do when you have to raise both sides of the car? You would have to buy a second jack and second one of these. I assume this is used when you have no other spot to place a jackstand. The Rennstand by Safe Jack is much more usable. Jack it up with the Rennstand and secure it, then you can remove the jack and use it for something else.

What are the chances the wheel axle of the jack where this support puts the load was designed to take this load? In the jack shown, the wheels are very close to the axle support, meaning it minimizes the bending moment on the axle, and puts most of the support force into the frame through shear. Loading the axle with the weight of the car in the middle greatly increases the bending force put into that axle. Would it hold it...probably, but was it designed for it...I doubt it.
 
You get what you pay for. Some people spend $4 for a Starbucks coffee every day. I don't mind spending a little more for tools that give convenience and last for years.
Oh, I get it. If I used them everyday I might see the case. Or just save even more and get an at home lift.

Or I can buy conventional jack stands and keep my jack there too. The odds of both failing are pretty small.

Like I said, I could see $40-50 per corner. $140-$180, not sure the value proposition is there for the home DIY'er.

You still don't get the point of these or at least the Rennstand. On many cars there is just one spot on each corner where the car can be lifted. If you jack it up from there with a regular jack, you can't now magically place a jack stand there in the same place as the jack to keep if raised. The Rennstand allows this.

No, I get the point. Seems more like taking advantage of no other options.

It's a clever idea, and I have no problem with folks getting paid for a clever idea.

Just seems it's a small market, as most cars DO have multiple places for support. Maybe those who shop things named Renn* have fewer options and / or are willing to pay more.

I certainly was not clear that I have options and others might not. So while I didn't express it very well, I do understand why it might be attractive to some.
 
Yes it's made for cars with no other options to lift at. On older body on frame models it's not too critical and often have solid rear axles to lift from as well. Many later unibody models have just one designated lift point on each corner which is fine when using a lift, but not convenient with a jack.
 
I haven't read all the posts or evaluated this product yet, but the concept is similar to the safety supports on front loaders. Makes me want to say "why didn't I think of that?" :

If they are meant as a replacement for Jack stands, there would be no Jack stand present for which to provide extra safety.

Neat device for sure, but not very useful for anything I own or regularly work on, especially at that price point.
 
For those complaining about cost, watch their video in the link in post #1. It tells you everything you need to know, specifically that their target consumer is the Zelenda Tool/Pelican Parts/Sharper Image/Brookstone shopper.....

Sorry, not sorry, it's just true. Nothing wrong with it either - spend your money as you choose.

No need to apologize, we were asked for opinions and we obliged.

I just rewatched the video though, and I see no mention or reference to any of the brands or stores you listed. He gave a usage scenario and then demonstrated the tool’s use.

Unless using a high-end car to demonstrate its usage on counts, I get no inclination of who the target is from that video.

Those cars usually have a jacking point somewhere under the suspension or drive drain. More than just the jacking spot for the spare tire jack.
