Video Transcript for Ultra-Fab Ultra Scissor Jacks Review

Speaker 1: Today we're gonna be taking a look at the Ultra-Fab ultra scissor jacks. For the two-pack with crank handle part number's UF48-979031. And for a single replacement, part number is UF48-979032.They're gonna stabilize our camper, keep it from moving around. So it's not so important really during the day. You don't want a lot of movement in your camper, of course, during the day, but as people start to go to sleep, other people stay up a little bit later. As you're getting in and out, you can really disturb that.

Your camper's gonna move back and forth. Any movement in the front of the camper, we're gonna feel in the back of the camper.So, by using a properly-working set of stabilizer jacks, we can eliminate a lot of that movement. We're gonna take a look at the tire intersection. That's the best area where we can see some movement. And we'll walk around in the camper before, we'll get our jacks installed, walk around in it after.

I think we'll see a pretty big difference.All right. We'll start just by walking in the camper. And remember, no stabilizer jacks at this point. You can see that movement and that shake. And as we get inside, walk towards the back of the camper, or towards the front of the camper, really see There's quite a bit of movement.Now, to lower our stabilizers down, we're gonna use our jack handle.

Now, if you get the two-pack like we said, you're gonna have the handle that comes with it. If you're just getting a single for a replacement, it's not gonna come with a handle 'cause you probably already have it.Now, you'll crank this to the left to lower and then to the right when you wanna raise it back up.Now, if you don't wanna use a crank handle like this, you're gonna use a three-quarter-inch socket or you can use the Ultra-Fab speed socket, which is part number UF48-979005.Now, we're gonna take all of our stabilizers down once our trailer is level. These aren't really designed for leveling. These are designed for stabilizing. So we'll bring them down til the make contact on all four corners.

At that point, wanna put just a little bit of pressure on them. That'll give us that stabilization effect.Once we have those deployed, I'm gonna take basically the same path I did before through the camper and you'll see what a difference it makes.We are up the steps, inside. Moving towards the back, back up towards he front. I can tell you, inside it feels much more solid. You don't feel the camper shifting side-to-side as you move around.Now, overall, this stabilizer jack is gonna by much more sturdy and stable than what you're gonna get from the factory. And really, it's stronger than a lot of the ones that we offer from different competitors. This one offers a 6500-pound capacity, so as a pair you're looking at 13,000 pounds. A lot of the other ones that you're gonna see are gonna be five thousand pound, maybe a six thousand pound capacity.I also like the screw mechanism that you see here. It's a little bit larger than what we see on some of the other ones. It's gonna come pre-lubricated for you. Yellow zinc here on the end and on our barrel nuts here on each side, which cause our jack to operate. That should keep corrosion to a minimum.Really, all you'll have to do every now and then, just add a little bit of grease here in this working surface. Keep everything lubricated. They should last a very long time.Got steel construction here on our arms, with a black powder coat finish. So overall, really good, resilient to any of those kinds of elements we might encounter while we're heading down the road.From side to side, we've got nine inches. From the front edge to the back edge of our foot plate, we've got five.Now, as far as the attachment point to our camper, you can see our plate here. This is gonna be three-and-a-half inches wide. And overall, from the end here to the opposite end, we're looking at about seven-and-quarter inches.This is gonna be an excellent foot plate for most surfaces we're gonna be camping on. Maybe soft sand, really soft dirt or mud, you might need to put something down, like a piece of wood, to give it a little bit more energy dissipation. But outside of those situations that you might not be camping in anyway, these are gonna do a great job on any harder surface.Now, overall we've got a 30-inch distance of travel from our jack. So that should work out with just about any camper, even one like this where it's set up a little bit higher. These are available in a 24-inch variety as well, if you need a little less space or if you don't have quite that much room. Those would be a good option also.These Ultra-Fab jacks tend to get very good reviews. It's kinda like Gene S. Says, "The quality is great and they fit right where the previous jacks fit. The travel trailer feels more stable with the new jacks and I can now get a little help when minor leveling is required. I should've done this right away, not after coming back from a 7,000-mile trip."Now, your stabilizer jacks are connected to your frame. You can see here, in this setup they're using three self-tapping screws on each side. The great news is, these brackets are pretty universal. So swapping out stabilizer jacks doesn't take a long time, doesn't take a lot of effort. Just gonna get these backed out of here.And once we get all of our screws out, we'll be able to get this old one out of the way.We've got four holes here for attachment. Oftentimes you're gonna see self-tapping screws used in this application. This is right up to our bumper beam here. Now, if you're adding these, maybe you're adding these to an enclosed trailer, something that traditionally doesn't have stabilizers, just wanna make sure you're on a solid piece of steel, like right here, or even on your frame here. That's gonna give you a great attachment point, make sure that you've got plenty of support there.Got our new one. We're gonna bring it up. We're just gonna re-use our existing hardware.Use one to hold it in place, get our other ones lined up, and install.Now, these can also be welded right onto your camper or your trailer, whatever you wanna do. So we can have it welded just basically all the way around the seam there. Anywhere we can get a good weld on. These are number 14 self-tapping screws. They also recommend the use of a three-eighths bolt. If you're gonna use a three-eights bolt, definitely use something that's at least a grade five.And that's gonna complete our look at the Ultra-Fab ultra scissor jacks, offering 30 inches of lift and a 6500-pound capacity.

This pair of scissor jacks can be either bolted or welded to the frame of your trailer or RV. Worm-gear mechanisms won't slip. Oversize footplates help to eliminate sinking and tilting.

These jacks are well built and have the extra height for uneven surfaces we were looking for. I find mounting this type of jack at a 45 degree angle to the frame is more stable than parallel or perpendicular. We used them all year and they are fine. My only comment to the maker is, something about the set-up of the threaded rod and 'nut' makes running them up and down take more force than should be needed, even before the base hits the ground and they pick up the weight of the trailer. They were that way out of the box. I use a battery-powered impact driver with a 3/4 socket to extend and retract, so no problem for me, but someone using the little hand crank supplied would build some muscles cranking them up and down by hand. I would purchase again if I needed replacements. 569561

Thanks so much for the awesome customer service! Our order was delivered promptly! We are very satisfied customers! Thanks, Derek! 293875



- UF48-979031
by:

Jacks mounted easily and are sturdy enough to lift/support my 27' C class. Only thing a little flimsy is the crank which needs to be longer and a little more sturdy. It'll do the job but I'll probably look for another crank. 61611



- UF48-979031
by:

Great jacks and very durable and easy to install. Must take into consideration the extra inch on each side once they are up and if you are using them on a trailer. They may stick out too much, therefore they will require special installation and even make necessary adaptations for attachment. 280690



- UF48-979031
by:

Very Poor quality. One of the jacks broke the second time I used them. The nut on the end of the screw that raises the jack broke free. I was only lifting one corner of a horse traier (no horses in the trailer). The Trailer leveling blocks work fine, just as advertised. 355219



- UF48-979031
by:

An excellent quality scissors jack. I went with a 30 inch vice the 24 due to needing the extra lift in unlevel ground. They protrude about 4 inches on the sides but does what I wanted. I will replace the front ones sometime next spring using the 30 inch jacks also. 155687



- UF48-979031
by:

works as expected and as usual for these not for use to free tire from the ground. I liked the extended height of these. they Will help stabilize my new 34' camper. defiantly need to use a drill to extend or retract them. takes quite a few turns to raise or lower a couple inches. 155466

I purchased these jacks for the rear of my small motor home. They were shipped very quickly and arrived the same.They look and seem very sturdy but I have not used them yet. I am eager to see if they will stabilize my motor home when deployed. 592591

Product was exactly as expected. However I should have ordered the 24" lift instead of the 30" lift. Spoke to Sheila last night and she assisted with the return and the order for the correct size. As always it has been a pleasure dealing with etrailer. 575640

- UF48-979031
by:

Installed these on the rear of a nine month old 44 foot toy hauler. Why you ask? Well, I got tired of the error and fault codes associated with the electric leveling system. These jacks are heavy duty and I like the 30 inch option since this will leave plenty of jack unopened and I suspect will deliver a steadier support. Mounted in about thirty minutes and looks/works great. Electronics are good when operates properly and without error, but there is something to be said about the old manual way. Highly recommend. 517614

These stabilizers were a replacement for two on my toyhauler and have longer reach and are made stronger than the one's i replaced. 510495

I thought they were well worth the money. My only issue was I had to mount them perpendicular to the frame. I was hoping they could have been mounted on the frame work of the tongue. Since I had to mount them were I did they stick farther than I like, but they work great. 496716

After a year, I found these jacks to be well made and functional. I camp in some unstable areas with a few Highs and Lows. The extra reach of these jacks is well worth the price. Of course, I have to maintain the screws with a little grease once a year. I fully recommend these jacks! 342063

Do you have a question about this Camper Jack?


  • Recommended Largest Stabilizer Jacks For Jayco Octain Trailer
  • For your Jayco Octain, I recommend the Ultra-Fab Ultra Scissor Jacks - 30" Lift - 6,500 lbs - Qty 2 # UF48-979031. The overall length of the mounting plate is 7-1/4 inches, and the width is 3-1/2 inches. I've attached measurements in the attached photo to assist. If you want an even more stable system, I recommend the Ultra-Fab Power Twin II Electric Stabilizer with Dual Motors - 30" Lift - 6,000 lbs # UF39-941705 or the manual crank version # UF39-941704. These systems are adjustable...

  • Can Ultra-Fab Power Twin II Stabilizer Jacks be Used on a 2017 Minnie Winnie 31K
  • The Ultra-Fab stabilizers # UF39-941705 and # UF39-941704 are very similar and have all of the same specs. But there is one important difference. Set # UF39-941704 is manually operated and # UF39-941705 comes with 2 motors for electric operation. It might be possible to install a set on your 2017 Minnie Winnie 31K but there isn't a lot of space on the underside of that RV so it is possible, even likely, that the stabilizers will not fit. When fully retracted the stabilizers will hang...

  • Reducing Movement in a 5th Wheel Trailer While Parked
  • Movement is normal when it isn't controlled. But when stabilization products are used then the movement can be reduced if not eliminated. You mentioned that you have tried things to correct this problem but did not mention what those things were so some of my recommendations may be something you have already tried. First we have to determine the nature of the movement. Is it side to side, front to back, or both? The front to back movement can result from slight movement at the trailer...

  • Recommended Front Stabilizer Jacks For 2016 Forest River 265RLDS
  • For your 2016 Forest River 265RLDS, I recommend the Ultra-Fab Ultra Scissor Jacks - 30" Lift - 6,500 lbs - Qty 2 # UF48-979031. I also recommend using the Ultra-Fab Speed Socket Power Drill Adapter for Scissor Jacks # UF48-979005 to make adjusting a little easier and faster. If you want a really nice option with dual electric motors, I recommend the Ultra-Fab Power Twin II Electric Stabilizer for Trailers and RVs - 22" Lift - 6,000 lbs # UF39-941707. I've attached a couple videos to assist.

  • Recommendations for Manual Stabilizer Jack with 22 Inches of Lift

You can use Valterra Folding Manual Stabilizer for Trailers and RVs - 14" to 28" Tall - Aluminum Item # 020106 which uses a ratchet strap to raise/lower the legs. It would have to be placed in an easy to reach location though. Another option is to go with scissor jacks such as # UF48-979031. If you do go with these scissor jacks you can add Ultra-Fab...

The side jack makes me think 5th wheel or stabilizer jack but I will give all recommendations. If your 1993 Jayco Eagle is a 5th wheel trailer, I recommend the Stromberg Carlson Electric Landing Gear Set - Weld On - 34-7/8" Lift - 5,500 lbs # LG-1.

These jacks are able to be out of the way when not needed and then add 1000 lb capacity support when needed and up to 650 lbs of lift. This will give you the support and stability you desire for loading and unloading.

  • How to Prevent Rocking and Swaying While Parked on a Jayco Travel Trailer
  • In order to further stabilize your Jayco travel trailer, I recommend additional jacks and wheel chocks. The best way to minimize swaying and rocking would be to have a total of four stabilizer jacks, one for each corner of the trailer. If you do not already have four stabilizer jacks you can use part # UF48-979031 for the front or rear depending on where the jacks you have are located. Once you have jacks on all four corners you add further support using the Super Grip Chock Wheel Stabilizers...

I used an existing picture and circled the mounting plate that you referenced. The overall length of the mounting plate is 7-1/4 inches, and the width is 3-1/2 inches.

  • Scissor Jack Stabilizer Recommendation for a 7,000 lb Trailer
  • The capacity for scissor jacks is a static capacity which means that it can support up to that amount of weight but can not lift that amount.

  • The Ultra-Fab Ultra Scissor Jacks # UF48-979031 that you referenced is a quantity of 2 of the Ultra-Fab Ultra Scissor Jack # UF48-979032. So its the same jack, but one part number you get a pair of them and the other part number you get just one.

  • Recommendations for Jacks to Lift a Trailer 28 to 30 Inches
  • RV and trailer scissor jacks such as # UF48-979031 are meant for stabilization purposes but not lifting applications. What I recommend is to use a couple of farm jacks such as # RP7033400 which are meant for lifting. This model has a maximum lift of 42 inches. It will also be easier to use than scissor jacks. But they have to be used manually and each one raised evenly with the others. Another option if you want something permanently attached to the trailer is to use some landing gear...

  • Can Electric Stabilizer Jacks be Used on 2018 Ford Transit T 350
  • We do have a large selection of electric stabilizer jacks available, such as the Ultra-Fab Power Twin II # UF39-941707. This particular system has a weight capacity of 6,000 pounds and will fit RV frames of 42 inches to 77 inches wide. Also note that it will require 24 inches of open space under the chassis to mount properly. Since your Ford chassis likely has a smaller frame width, a better option might be a set of scissor jacks like the Ultra-Fab # UF48-979031 that provides 30 inches...

  • Stabilizer Jacks for the Front of an Enclosed Toy Hauler Trailer
  • The stabilizer jacks, # JB-20, are made to help support slide-outs on travel trailers and would not be the best option for your application. What I recommend is a pair of scissor jacks like # UF48-979031, one on each side of the trailer frame. You can actually use a power drill with the correct socket to raise and lower the legs to make it easier and faster. I assume that you have one in the trailer since it is hauling a drag car and all. You could use bit # UF48-979005.
