Using a Unijack

Begin using the Unijack by placing it on solid, level ground in a vertical position under the vehicle or object you wish to lift. Determine the best lifting point to support the bottle jack and line up the piston ram underneath it. Once everything is lined up correctly, turn the lever switch at the base of the piston clockwise to allow you to move the piston up and down. After you have the vehicle lifted to the desired height, the jack will automatically lock into place. The Unijack will then double as a jack stand to support the lift. To unlock the jack, simply turn the lever at the base of the piston counterclockwise and the hydraulics will slowly move in a downward motion.

This is a compact jack that is easy to use. I bought this to use on our popup camper and it works great. Easy to carry and store. It takes up little space but is there when you need it.

I have been more and more business with etrailer the past few years. Their service, price, product knowledge is impeccable. I learned about the Powerbuilt Uni-Jack on the etrailer website. Watched the instructional videos posted there and read the reviews. It’s an excellent powerful jack and very safe. Surpasses all expectations. I highly recommend the jack and etrailer.

Love the hydraulic jack, can lift an elephant out of your garage. Well almost...anyway I use it to lift my boat trailer and my SUV if I get a flat tire. Works great and has a solid wide base for balance on the ground. Very compact and easy to use!



by:

Size $ height of this jack works well for my two trailers...one 17' cargo, and one 17' travel trailer - toy hauler). Safety lock feature works like a charm.



by:

This is a great hydraulic jack...it is small enough to fit under my ATV...also used it to lift my rear deck mower to fix the blades...with the safety bars locks, it is a two-in-one jack...



by:

I bought this in case I had a flat on my camper. It fits perfectly under the axle between the u bolts. Tried it out a couple times. Worked flawlessly. The built in jack stand makes it safe as can be.



by:

This is a good product but a little flimsy. Deeper welds with thicker steel would be better. They were used on a 2017 CRV and with 4 wheels off the ground I could "wiggle" the car a little. The jacks were flexing. I don't think I will be going under the car for anything with these holding it up. The jacks are good for tire swaps/rotations and that's what they will be used for.

  • Overall Weight and Height of Powerbuilt Unijack Bottle Jack with Built-In Jack Stand
    Hey Nick, thanks for reaching out! The Powerbuilt Unijack Bottle Jack with Built-In Jack Stand # ALL620471 weighs slightly over 23 lbs. I know the resting height is 11" and the lifted height is 21", but aside from that I don't have any other dimensions. I tried reaching out to Powerbuilt, but they haven't gotten back with me on the overall dimensions. Just curious why you would need other dimensions for this part, if you don't mind letting me know.

  • If Running Boards are Installed at the Jacking Points on Sprinter, How Would I Change a Tire?
    Hello Tom, Great question. The Aries RidgeStep Running Boards w/ Custom Installation Kit # AA2055539 is designed for the Promaster 2500 and 3500 models, it is not listed to fit your 2021 Promaster 1500. The closest thing we have to the style you were looking at is the Romik Connect RPD-C Running Boards w/ Custom Install Kit - 6" Wide - Black - Aluminum # RMK68FR for the ProMaster 1500 with 136" wheelbase. I reached out to my contact at Romik to ask where they install, they also install...

  • Do You Have a Hydraulic Scissor Jack?
    Hey Mike. I don't have a hydraulic scissor jack, but I do have an electric one. It's the Performance Tool Electric Car Jack item # PTW1609. It has a 2-ton capacity, extends up to 14", and plugs into a cigarette lighter. The Power Mountain Tallboy Off-Road Bottle Jack - 8-1/2" to 37-3/4" Lift - 6 Tons item # PM34FR you were looking at is what all of our hydraulic options are going to be similar too.

  • Oil Plug Location on Powerbuilt Unijack Bottle Jack with Built-In Jack Stand
    When I reached out to my contact at Powerbuilt they indicated that the hole in the side of the Powerbuilt Unijack Bottle Jack with Built-In Jack Stand # ALL620471 is actually a plug that you need to remove (see attached). This being a plug would help prevent oil leaking out and would help keep the system "pressurized" for lack of a better term. Attached is a review video for you to check out. If your jack looks different please shoot me a photo so I can compare that to what we have on our end.

  • Can The etrailer Scissor Stabilizer Jack e29VV Be Used For Lifting The Trailer?
    Hello Phil, thanks for reaching out. Scissor jacks like the etrailer Scissor Stabilizer Jack # e29VV are only for stabilizing the trailer. They have a 2,500 lb support capacity. They should not be used for lifting the trailer to change a tire. For that a better option would be a bottle jack such as part # ALL620471, which has a 6,000 lb capacity and can be used for lifting the trailer for maintenance. What trailer do you have? How much does it weigh? Reply below and let me know if there...

  • Can Ultra-Fab Stackable Stabilizers UF48-979003 Be Used To Lift The Trailer
    Hello Wendy, thanks for reaching out. Stabilizer jacks like the Ultra-Fab Stackable Stabilizers for Small Trailers and Campers # UF48-979003 should not be used to lift the trailer. They should be used for stabilizing the trailer only. If you need to lift the trailer like to change a tire it would be better to use a bottle jack like part # ALL620471. This is safe to be used for lifting the trailer and has a 6,000 lb capacity.

  • Recommended Jack to Lift a Trailer to Change a Tire
    Trailer stabilizer jacks like # TJSCHD-24 are not designed to be used to lift a trailer and hold it up for maintenance. Their purpose is to stabilize the trailer while it's parked and no more. What you're looking for is a jack to hold the trailer in the same fashion one would hold your car to change the tire. For this we have several options like the Performance Tool Electric Car Jack # PTW1609 which has a maximum lift of 14 inches and can support up to 4,000 pounds. If you need an option...

  • Recommended Replacement Wheel and Tire for a Triton LTWCI X Trailer
    I checked online and it does look like your Triton LTWCI X trailer uses a 5 on 4-1/2 lug pattern. You may want to measure and confirm this. Otherwise the Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel - 5 on 4-1/2 - Load Range B item # AM30580 you were looking at would be a great replacement. We also have this tire wheel combo in a galvanized rim item # AM30670. This will protect your wheel against rust. For a jack to change your trailer's tires, I recommend the Powerbuilt Unijack...

  • Recommended Jack for Changing Tire on 8,200 Pound Tandem Axle Trailer
    The Powerbuilt Unijack # ALL620470 referenced in your question has a weight capacity of 4,000 pounds. This is likely enough for your 8,200 pound trailer, but I recommend going up a bit with the Unijack # ALL620471 that is rated for 6,000 pounds. This will give you more of a safety margin for jacking up the trailer to change a tire. This bottle jack features a lift range of 11 to 21 inches and the safety bar locks the jack into place removing the need for jack stands. I have attached a...

  • Wheel Change Jack Compatible with Triple Axle Trailer
    The Andersen Rapid Jack # AM3620 is not designed to work with triple axle trailers. If you are looking to use it for leveling, then I recommend the Andersen Camper Wheel Chock and Leveler # AM3604 for your application. The similar # EZ-JACK is also not for use on triple axle trailers. If you are looking to use for changing a tire there unfortunately isn't a drive on solution we can offer. You will need the Powerbuilt Unijack Bottle Jack with Built-In Jack Stand - 21" Lift - 6,000 lbs...

  • Recommended Jack for Trailer to Change a Flat Tire
    For a jack to use in an emergency to change a flat tire I recommend using the Powerbuilt Bottle Jack # ALL620471.

  • Best Device to Lift Trailer When Changing Tire on a Triple Axle Trailer
    Yes, the Blaylock EZ Jack and Wheel Chock part # EZ-JACK can be used on a triple axle trailer like you have but you would need to turn the curve up, opposite the wheel, and drive up on the jack and you will be able to change the tires. Otherwise the best way to change a tire out on your boat trailer would be with a jack and jack stand for which we have the Powerbuilt Unijack Bottle Jack with Built-In Jack Stand part # ALL620471 that is both. I have attached a review video of both options...

  • How To Lift and Store a Travel Trailer with Torsion Axles
    The only option I have for you to store a torsion axle trailer with the wheels off the ground is by using jack stands, the Powerbuilt Unijack Bottle Jack part # ALL620471 would be a good option as they have built-in bottle jacks and offer up to 21" of lift. These bottle jacks will need to be placed on all four corners of the trailer under the frame, not the axle tube. This option will then allow for you to remove the wheels/tires and store these in a cool dry area while also allowing for...

  • Which Bottle Jack for 2018 Coachmen Apex Nano 193BHS Travel Trailer
    I have a solution for you, but I don't believe the Powerbuilt # ALL640405 is going to provide the needed length of piston to lift a trailer that's already 22" from the ground; this unit is only capable of lifting up 12" and you won't want to stack up multiple boards under and on the bottle it to make it work. The best available solution would be the Powerbuilt Unijack Bottle Jack with Built-In Jack Stand - 21" Lift - 6,000 lbs # ALL620471, which can extend to 21" tall and has a 6000-lbs...

  • Jack Recommendation for Using as Emergency Jack for Boat Trailer
    The Powerbuilt Unijack Bottle Jack part # ALL620471 that you referenced is a great choice because it has more than enough capacity at 6,000 lbs and since it has a built in jack-stand it's safe to use without separate jack stands which allows you to save space by not having to also have jack stands.

  • How To Replace Jack Oil on Powerbuilt Unijack Bottle Jack
    The only place there might be a leak on the # ALL620471 is the rubber plug on the side. Any hydraulic jack oil is fine. There are some options that have "stop leak" so you might want to try that. When adding oil, remove the plug and fill it to just below the hole with the jack sitting upright.

  • Trailer Jack and Jack Stand Recommendation for Trailer with Dexter Tor-Flex Axles
    You'd have to jack your trailer up by the frame with a bottle jack like the # ALL620471 since the TrailerLegs Tire Saver Stands # 326-TRLLG-4 require your trailer to have standard axles. The part # ALL620471 also doubles as a jack stand too for if you were planning on storing the trailer.

  • Recommended Jack For Raising Sunray Travel Trailer To Change Tire
    To lift your trailer I recommend using a jack like the Powerbuilt Unijack, part # ALL620471. This jack has a 6,000-lb weight capacity and the lift range is between 11 and 21 inches. Scissor jacks like part # JSC-30-IND that you referenced are not recommended for lifting trailers and are to be used for stabilization only. You want to make sure the wheel on the other side of the trailer is chocked and not able to move when changing the tire.

  • Jacks for Lifting and Lowering 5th Wheel RV Camper
    The Lippert Scissor Stabilizer Jacks # LC285326 are only stabilizer jacks that should not be used to try and lift or lower your 2014 K-Z Durango 336RE. For lifting the front for connecting and disconnecting the camper there are a couple options to help you with that. The jacks will have a manual override on the top of the jack. You will remove the access cap and use a ratchet to move the jacks. You can also disconnect the wiring on the jack and operate it remotely by powering the jack...

  • Can Stabilizer Jacks be Used to Lift and Support Trailer?
    Stabilizer jacks are not designed to lift and support trailers for something like taking the wheels off; they are meant to simply level and stabilize by handling a portion of the trailer's weight. I would not be able to recommend using stabilizer jacks to keep a trailer up. A better option would be a bottle jack such as the Powerbuilt # ALL620471 to remove tires. I've added links to a pair of video reviews of this jack for you to take a look at.

  • Can Trailer Stabilizer Scissor Jacks be Used to Lift a Trailer
    Scissor jacks for trailers such as # TJSCHD-24 are used for support but not lifting applications. For lifting I recommend using a bottle jack such as # ALL620471 and then using a stabilizer jack to support the trailer at the proper height. Bottle jacks are great since they don't take up a lot of space and still have plenty of capacity.
