BAOSHISHAN4 Ton Bottle Jack 10-5/8" to 24" Lifting Range High Lift Double Ram Bottle Jack Hydraulic Welded Jack Truck Jack

IT WORK WONDERFUL!

I chose this jack because of the max lift height and capacity. My truck's axles are about 22" above the the ground, so I need a tall jack unless I want to use excessive amounts of blocks (which isn't safe). Truck weight is around 12k pounds empty, 16.5k loaded. So a 12t jack gives a 100% safety margin empty and 50% loaded.This is the tallest 12t+ jack I was able to find.The jack arrived in good condition. Its big and beefy and looks well made. I did a "test lift" of my truck (empty) and it worked just fine. It lifts slowly, but that's to be expected given the high weight capacity.BTW, I used a Safe Jack axle cradle to safely lift the truck. Using a bottle jack with a small round screw pad on top directly on an axle is not a good idea. The Safe Jack 20t "universal lift pad" fits this jack. I still need to get a bigger and thicker base plate to place under the jack for stability and to prevent sinking in soft dirt, and to get a little more lift.

The versatility of this jack is fantastic! Seems to operate smoothly and be a quality item. "Double Ram" is not really accurate, but that's the world we live in. It is actually a "2-Stage Ram" since one ram is encased inside another. No big deal.... semantics. In operation the larger ram extends first due to laws of physics. This means that until the larger ram is fully extended each pump of the handle results in less lift than when the smaller diameter ram starts lifting. ALL brands of this design operate identically. Alas, this fact also means that once the smaller diameter ram starts lifting it also requires more force per stroke but greater lift per stroke. Get it? Common sense. For me, I have learned to purchase a jack with at least twice (i.e., > double) the capacity than what I actually plan on using it for. Takes more strokes and time, but less force required per stroke. Tradeoffs. Would have rated 5 stars if the price were <$100.

The jack was shipped with no or little oil. You have to pump it for 5 minutes to get it to extend and does not reach its full height. The second stage does not move very far. The jack is very difficult to retract into rest position. It is defective and dangerous to use.

This works great for our 2020 Lincoln Aviator. The OEM jack actually BROKE when using it! Luckily no damage to the vehicle. This has a wider base and the 24" lift is enough to get the wheels off the ground without needing additional blocks under it. We are just keeping it in the back with the spare tire.One nit-picky thing, though, is that it doesn't fully retract on its own when lowering. So you have to kind of yank it out from under the car and then manually push down on it to get it collapse all the way. But that's common among these hydraulic jacks.

This jack has the lift distance I need to lift a high GMC 2500 HD 7,000+ pound truck, with lots of pumping, but still good and not hard. The problem is that the jack release valve has no limit. If you turn it too many times counter clock wise to release the pressure, it will fall out and all the jack oil will come pouring out of the jack. There is no warning about this in the manual. The jack has a rubber oil fill plug to refill the jack with oil, but you can't take the rubber plug out without destroying it. The manual says call customer service for help, but doesn't list a phone number or email. I may have to return the jack if I can't find a replacement rubber oil fill plug. Hate to do that because it lifts my truck so well. Very nice if you are careful and know not to turn the relief valve too far. Update: I contacted the manufacturer thru Amazon Feedback. They emailed me today and seem willing to help. Update: 4/19/2023. The manufacturer is really willing to help. They are sending me the new rubber pug I need from China, free of charge. They are also very receptive to any suggestions that could improve the jacks design. This is the only jack that lifts my GMC 2500 HD from the ground. So, I was really worried about sending it back. The Jack fits on the floor in back of the front seat, with a jack stand. Great Jack.

Was looking for a way to remove a tire from Tesla M3 and this won't work by itself. No room for the puck. However, there is a workaround. We are also RV'ers and have RV leveling blocks. Even with a flat tire, driving a couple of feet onto the leveling blocks is possible and provides the ground clearance needed. Only 3 bloc blocks are needed and they are very light to travel with.

Just used the jack for the first time…seals blew on it and I was unable to finish the job I was working on. DO NOT BUY THIS PRODUCT!
