5 Ton Double Ram Bottle Jack, High Lift Hydraulic Jack | Heavy-Duty Welded Steel, Overload Protection Valve, Anti-Slip Base, Portable with Case, for Truck RV SUV

First of all, I decided to purge any air out of the system introduced in shipping for any problems later. For instance, my release valve sets at 10’o clock closed position, I loosen it 3 turns ccw (back at 10’o clock). Then pumped it 20x to make sure there’s no air in the system, after that tighten the release valve and you should be good to go. Note that this jack does not recede back by itself without weight on it. I just turn mine 3x ccw and it was easy enough to push the pistons down by hand. Warning don’t back out the release valve too much or you’ll have hydraulic fluid all over your floor. 3 turns were enough for mine. The jack itself is 16 lbs, with the 3-section handle total is 17.4 lbs The overall max height is 24”, the first section that comes up without lifting any weight is the smaller diameter and that took 64 pumps to raise 7”. Then after that the larger diameter will raise it another 6.5” which takes additional 133 pumps. I don’t mind the number of pumps, just here for reference; I need the capability of lifting it very high, which this jack does! When lifting a car, the smaller diameter ram comes up first and when it hits restriction then the greater diameter takes over to do the initial lifting. After the bigger diameter ram reaches limit, the smaller ram takes over and lift the car to the 24” limit.

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.

Leaking in one week.

Arrived wrapped in bubble wrap. Handle is 3 pieces. One piece deformed and wouldn’t seat into other piece. Since I needed it, I used bench vise to reshape and get it into its mate. Of course it’s not coming back out. So far seems the jack itself seems to work properly. Just updated rating to 4 stars based on seller's prompt and satisfactory response to my issue. Also, the jack has been holding my boat up for a week now with no slippage.

12/14/2024 UPDATE: Used jack one time, lightly. Walked into my garage the other day and the jack was sitting in a POOL OF OIL! Took a while to figure out where the leak is coming from, but can see that oil is leaking from the threaded portion of where the actuating cylinder (i.e., the part you cycle to extend the jack) is threaded into the jack body. It is about a 1/2" pipe thread near the base of the jack. I am hoping the manuafacturer will see this review and contact me to make it right. Not happy about this and I also have purchased a 5-ton model in the meantime. Original: 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.

I tested out lifting the Tesla Cybertruck, which required 18" clearance to remove the tire. Lifting was easy-peasy and only required two metal pump extensions, even though the jack came with three. The jack arrived brand new and appears to be of very good quality. It just takes a little force to lower the jack to its base setting. It's well worth the price compared to lower-cost 4-ton jacks, which typically can only raise up to 16 inches. I couldn't be happier with the purchase and highly recommend it for high-clearance vehicles if you don't need a 12-ton bottle jack, which will be much heavier.

This is a great time saver way to lift my RV trailer if needed. I waned a larger jack so that if I or someone else needed a bottle jack for a safe repair I would have one. Easy to operate and has a higher lift than other bottle jacks. I also purchased a bottle jack adapter sold separately to straddle an axle if needed.

Out of the box, it feels solid and well built. The blue color is the first thing that catches your eyes, but the weight of the jack is undeniably the second feature. Everything about this screams well built. I bought this because of my lift and additional weight on my rig and the standard bottle jack that my rig came with won’t but it for a simple tire change. With this now I know I can at least swap out my huge tires. But I haven’t had a need to use it yet, other than a quick test to make sure it works. I’ll update once I actually get to use it.

Heavy duty excellent qualty.
