2Ton (4000lb) Scissor Jack Steel Universal Stabilizer Leveling Repair Tool Rust-Resistant for Car Truck Vehicles

So I wanted a scissors jack that could lift the car using the impact driver I use to take off lug nuts. That way I only need one power tool to do both jobs and don't have to drape a long cord out of the car and carry a dedicated, expensive, powered jack. As an additional bonus, if it could be used when I rotate tires I don't have to pull out the 100 pound floor jack.So reading reviews I noticed how and why other scissors jacks failed: some just collapsed under load (even though they were rated for 3000 pounds) and others would strip the threads of the jackscrew. For the units that collapsed, I can see if the load isn't placed at the center of the top crossbeam there could be a problem that could cause uneven stresses and the buckling. So the Xinner fixes this with the swivel saddle up at the top of the jack that engages the ridge on the vehicle. This saddle ensures the load is in the center of the crossbeam. A lot of other scissors jacks don't have this, so this fixes that problem.The next issue is with the jackscrew itself running down the center of the jack. The Xinner arrived with many burrs and machining chips in the jackscrew along with some very thin grease. I fixed this by running the jack all the way up, cleaning off all the factory supplied grease with solvent, and applying molybdenum grease along the entire length of the jackscrew, then running it full down and up several times to distribute the grease. I had bought two of the Xinner, and one had a metallurgy flaw (void) in the jackscrew, but fortunately it was at the end of the travel when there'd be no load on the jackscrew. Otherwise it would be a problem and I could see how the screw could get damaged or strip out if that flaw were higher up on the jackscrew. But the burrs on the surface were shoddy. Fortunately the moly grease eased that issue.Next I got a scissor jack adapter (https://www.amazon.com/gp/product/B00X3ENPJ8/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 ) that allows the impact drive to interface with the scissors jack. You have to be careful with this to align the adapter to the jackscrew to keep it from wobbling while the impact driver is running. Also I had to get a nylock nut to keep the adapter from loosening on the jack's eyelet hole, the eyelet is tapered a bit so the clevis flange on the adapter doesn't quite sit square, ergo, the nut can back out while the impact drill is running, thereby sending parts flying everywhere. But get the nylock nuts and all is well (The adapter I mentioned above uses M10 metric nuts)So, after all that, the battery powered impact wrench jacks up the car in15 seconds after you do all the above. And you can throw away the crank handle that came with the Xinner, as it's useless anyway and as someone mentioned, it doesn't work well if you try and use that.So, I'm derating a star from 5 to 4 after modifications based on the burrs on the jackscrew and bad lube supplied by the factory, but, once modified, it seems to work well.

I was a bit concerned open receiving the jack because the box was heavily damaged, but it was ok after opening it. The jack worked great. I bought it for my daughter's car since Kia doesn't supply a jack anymore. I tried it out on her car and it worked well. Overall for the money it's a good value.

I used this to change a tire and oil on a 2006 Scion XA. The jack appears to be similar to the model that came with the car. All in all, it worked. I would not say that it's the sturdiest jack in the world but it serves its purpose for smaller cars for sure. Can it really support 2 tons? I kind of have my doubts but it certainly handled my vehicle pretty well.If at all possible I recommend using an absolutely level surface to use this jack. Also, be sure to use any emergency breaking possible to avoid the car rolling this jack over.

Used this to change my wheels, and after getting to the third wheel it had already bent just simply due to the car wanting to roll slightly as it lifted. By bending, it knocked the gears out of whack so the teeth no longer lined up. Difficult to bend back into place, but even if I did the structural integrity is already compromised. Cheap price, cheap product.

The jack seem to be strong enough, but I have problem using it on three different cars. As it goes up it the head starts getting crocked and does not seem stables. As a result there has been a couple of time when it tilted back and the car fell off the jack so I can't us it anymore as I don't trust it.

Bought this after my stock scissor jack buckled during a wheel change on the side of the highway. Nice and strong and no more worries.

The crank handle is ridiculous. Very difficult to turn. Ended up buying an adapter that replaces the crank handle with a braked bar/socket wrench for additional $12-13.

My wife ended up rolling the factory scissor jack we had for her 2005 Subaru Forester (Didn't engage Parking Break). I got this to replace it. Biggest concern i had was if it would fit in the pre-molded Styrofoam slot in the cargo area. It fit perfectly. I cranked it once and it seems plenty strong enough to get the job done in an emergency. Any normal to compact size car it will lift it plenty high enough and it compresses tight enough to fit under the car when the tire is deflated.
