Video Transcript for Ultra-Fab Power Twin 2 Electric Stabilizer Review

Today we're going to be taking a look at the Ultra Fab Power Twin II electric stabilizer with dual motors. Offering thirty inches of lift and a 6000 pound weight capacity, it's part number UF39-941705. The twenty-two inch lift model with the 6000 pound weight capacity is part number UF39-941707. For those of you that don't have a power supply available these are also available in a manual configuration, part number there with a thirty inch lift is UF39-941704 and they're going to have that same 6000 pound weight capacity. This cross frame mount jack system is exactly what you're going to need to both stabilize and level your camper or RV once you get out to where you're going. It has a dual motor, dual arm design. These work completely independently of one another.

As you can see our plate here is all the way down on the ground and if you look at the other side we've actually got that set up on a six inch block. Both of our motors are going to extend and retract as you can see independently of one another. That's going to allow our stabilizers or leveling kit to adapt to just about any kind of ground condition. Not only is the Power Twin II going to help us out as far as the side to side stability goes, as most stabilizers will. But what really sets this one apart is if you look at our bracket length here we're looking at a full thirty-six inches and we've got this sturdy steel supports that are going to go front to back. Not only is this helping us with the side to side movement but also the front and back as we're moving around inside. The Power Twin II can easily be mounted to the front or the rear of your motor home or RV or camper. They don't recommend them for use on the front of a motorized vehicle so you'll want to keep that in mind.

They're customizable fully to fit many different varieties of applications. They'll go anywhere from a forty-eight inch frame rail outside to outside, all the way up to the eighty inch so you've got kind of a wide range there that these are going to fit. The foot plates themselves are nice large footplates that you can see here. That's really going to dissipate this energy out and spread them out. That way we won't have any kind of sinking or tilting issues to deal with. Both of our motors are also going to have the greaser which is going to make lubricating of these very easy to give us good long use and years of service.

As you can see when not in use, these are going to tuck up very nicely up underneath the rear of our camper and everything's held in place, we're not going to have any noise issues. That will complete today's look at the Ultra Fab Power Twin II stabilizers available in both electric and manual operation. .

I love this product, I wish I'd bought and installed it sooner. It took some installing, you might need to solicit help from a friend unless you're stubborn like me, in which case it's doable solo. The wiring is the most challenging, I found adding a dedicated circuit directly from my battery via a heavy duty fuse was the way to go. The function and performance is flawless and makes leveling at the campground or storage location child's play. 655786

I Love these Electric Stabilizers, They work Great. They Make setting up and taking down, so much easier. The Duel Motors have plenty of Power and give you complete control of leveling both Sides Independently. The only Negative is the Glass fuse style Fuse Holders that come with them, They work intermittently at Best. Replace with the Blade Style Fuse Holders. Much Better. 607721

On a nice sunny day I pulled out my new Power twin Stabilizer set. The Ultra-Fab went together as the direction read. The sizing to the trailer frame was a bit of taking a part to slide together as it is a very tight fit. I was replacing a cheaper set put on by the trailer MFG. adding spacer to fill in for the longer and better frame work of the Ultra- fab Stabilizer. The power units went on without any fuss. I am very pleased with my handy work the ease of installation. etrailer was great support when I thought a part was missing in shipping. All parts were in the boxes when I open them all up. Thank you etrailer 189206

The Jacks are considerably more durable well built compared to the Lippert models. The lifting power is real and once on the ground the prevent movement of the RV by orders of magnitude over the other style jacks. I only have one in the center of a long trailer and it has stopped the bouncing and side to side swaying of the trailer. Just stepping onto the stairs to get in its rock solid. Also when all the legs are deployed the doors close way better than they ever had with just the Lippert jacks on the front and back. Definitely recommend to anyone thinking about a better jack than what's provided oem. 307523

The Ultra-Fab Power Twin II is a very robust stabilizer and works very well with the two heavy duty twin motor Ultra-Fab landing gear jacks I had previously installed on the front of our 32' fifth wheel. I like this product for it's strength and simplicity. It allows leveling and stabilizing without hand cranking or getting down on knees with a cordless drill and socket. I performed the complete assembly and install myself which replaced the two scissor jacks that came on the fifth wheel. This unit makes for a very stable platform. 291096

Ultra- Fab did a great job with this product. Extra heavy duty and a easy install. Very good quality mounting hardware included. Nothing else needed for installation. This system makes setting up at the camp site a breeze. If you are looking for a stabilizer leveler system your search is over. etrailer.com could not have done a better job. A great web site and fast shipping. Keep up the good work. 173391

Comments

The ultra fab stabilizer part # UF39-941705 is not designed to lift. If you are looking for a stabilization system that can also lift the trailer I recommend lippert Travel Trailer Leveling System part # LC672136
Electric Ground Control TT Automatic 5-Point Travel Trailer Leveling System - 10,000 lbs
$2,401.84
. 5 motorized jacks will lift the trailer and level it with a fully electric system. The system can be operated by the included control panel or with your smart device. The best thing about the lippert leveling system is that it includes hitch height memory for automatic leveling when you are ready to hook up again.

Quick follow up after a year or so of use on the Twill ll Electric Stabilizers. I have one set on rear and one set on front of my 28' Coach. I have found that it is better to use a solid piece of 12"x12" hard wood for the feet to rest on while setting up the camper at site. the plastic ones seem to push in after a bit and I have to re-adjust. As far as the Jacks are concerned, they perform as they should, making the coach very solid with little to no movement. I have had 0 issue's with them since I installed. Not a super easy task by yourself in your driveway but not that hard either. just take your time, run heavy gauge wire for power so no drop in amp. all good! thanks, 445259

Little intimidating at first, just took my time and it went together without any major problem. The problem that I had was dealt with quickly. It's solid and well built. Print on the instructions was a little small for my eyes. Having the instructions on line was a great help. 324280

Finally got around to installing my PT II Stabilizers 30" front and rear of our 26' Surveyor. Pre - assembled them to make sure they went together ok. Luckily I had two sources for power front & rear which made wiring easy, I used a Buss block to make all positive connections, grounds straight to frame, soldered all connections and heat srinked to seal. Using the 3/8" self tappers was fun.Well got it all together and all works well makes trailer very stable, don't have to worry about scissor jacks collapsing anymore. 422980


Comments

Working well they make our trailer very stable compared to the sizzor jacks that came on our trailer well worth the money. Install was easy and had them spot welded to frame.

Good product! 3 day delivery, no missing or damaged components. 2 hour install...an extra pair of hands is very helpful. I completely assembled the device, left all fasteners a litle loose, slid underneath my 36' trailer. Set width beforehand plus one half inch using jack legs to raise against trailer frame then adjusted finish width. Sure makes life easy for someone with physical limitations. 713754

Ultra-Fab Products Power Twin II Camper Jack Good product, however we bought it for our class c RV, it didn’t fit right but we were able figure a way to get it to work. 693112



- UF39-941705
by:

Having newer higher travel trailer the scissor jacks that came with the unit couldn’t reach the ground and blocking had to be carried. The electric stabilizers do come in different length legs depending on what you need. They work great, mounting them to the frame was a little work. I was able to do the work myself. Deciding where to mount your switches and how to run wire to them takes some planning. The jacks themselves are very sturdy when down and can lift the camper (not recommended). 673841



- UF39-941705

I want to give this product 5 stars as they are a very nice set of stabilizer jacks that are very heavy duty but I'd have to say that the quality control from Ultra Fab is not great. The connecting bracket, part # 39-841642 on both sets was very poorly fabricated. On one set the holes were not drilled in a straight line and therefor did not line up with the holes on the jacks forcing me to drill new holes and on the other set the bracket was actually a whole quarter of an inch narrower at one end than the other and the jacks did not even fit into the bracket. Due to time constraints and not being able to be down more than a day after cutting off the old jacks I was forced to cut the bracket and weld it back together straight so that it was usable. Costing me an extra 2 hours of time and frustration. Nice jacks otherwise but I advise to assemble them completely and make sure the parts line up before removing your old parts. 662077

After installation the stability or my toy hauler was increased X3. The installation was relatively easy and all that was needed was common tools and a floor jack. Wiring was covered by simple easy to follow instruction. Some shrink wrap and a solder gun make permanent water resistant connections which I recommend. 653355



- UF39-941705
by:

I received the leveller/stabilizer as expected. The instructions for installation were clear and I found it easy to assemble and install them. Wiring was a bit tricky because of my trailer design, but worked out fine in the end. I have just returned from a three week trip and can recommend this product whole heartedly. One thought I have had is that a manual version might be satisfactory, using a drill to drive the gears until they engage with the ground, and then using a manual crank after that. The motors are a bit slow to drop the feet to the ground because they also have the necessary torque and gear ratios to lift the corner of the trailer. All in all, a great product. 647307



- UF39-941705
by:

The stabilizer was a great purchase. It has lived up to it’s description as advertised. I did have to make some alterations. Because I have a slide out carrying rack on my 2010 Cougar 5th wheel, I had to weld the stabilizer to the frame so I could use the slide out rack. It works great. I highly recommend the product. 613986

The Jack's came really boxed up well. They came in 3 boxes. Assembly was really not a difficult task. I built them in my driveway and slid the right under the camper. I do recommend that you get a real good measurement of your trailer frame (outside to outside) before putting under trailer. That way you not crawling under your trailer 10 times to move adjusting bolts TRUST ME ON THIS ONE! These Jack's are really heavy duty. Must say they are a very well made. Better then the stuff new trailers are coming with off the lots. 608834

Nice product. Shipping was fast and communications were good. Heavy duty stabilizers, I'm sure they will be more stable than the old scissor jacks. The only problem I had was the one ear was broken off of the one switch. Does not effect function but when you buy something new you expect it to be right. 523701

Package received mostly in tack. Heavy stuff could use better packing. Product came together just like instructions say. Put wiring per instructions and inserted fuses. Turned the switches on and up she went. I will love it. No more manual leveling. The heavier 6,000 lb lift will be better for my fifth wheel 35 foot challenger. When it is up you can't tell it's even there. Mine is the twin 11 stabilizer with dual motors. 243048

Your going to love this product. I was able to fit on to a 1987 Avion travel trailer I renovated for my sister (spectacular renovation). It made the camper rock solid. You can't feel anybody walking around, no high wind movement. It felt like we set it on a concrete foundation. It is a well designed product I will use in the future if I renovate another classic beauty, even my own every day travel trailer. Great product. 614891

Review from a similar Ultra-Fab Products Power Twin II in Camper Jack


I got the jack for three reasons. My original jack was intermittent, it was bent and it did not level the trailer because it had only one motor. The new jack works great and it can level the trailer because it has two motors and the power required. It was not the easiest to install because of the increased size and it will not level the trailer if it is off more that 2 inches or so side to side. In spite of these drawbacks and the fact it added weight to the rear of the trailer I am very happy with the new jack. 372285

Very happy with the quality of this stabilizer jack!!

  • The Ultra-Fab Power Twin II Electric Stabilizer with Dual Motors part # UF39-941705 will work on most trailers but you will need to take a quick measurement of your frame rails (outside to outside) to ensure they are between 48" to 80" wide. I am almost positive your Palomino Puma is within this range but it will be a good idea to check this beforehand. I don't have any specs on a Palomino Puma to look this up for you unfortunately. The weight of the trailer will not be an issue as the...

  • Replacement Stabilizer Jack for LCI Power Stabilizer Jack
  • You are correct that the Lippert Stabilizer no. 1917771 is no longer made. For a replacement, I suggest model # LC337199 which offers faster operation and I believe a lighter weight. This single-motor unit extends up to 30-inches and I believe it will even match the existing mounting holes on your RV from your other stabilizer. The overall dimensions are 78" long x 20" wide x 4-3/4" tall. The mounting hole spacing is 68-11/16" from center-hole to center-hole. If you prefer a dual...

  • Difference Between # UF39-941705 And # UF39-941707 Ultra-Fab Stabilizer Jacks
  • The lift capacity and strength is the same for either of the power stabilizers you referenced. They both have dual motors which operate independently, making it easier to level the motorhome or trailer. The difference is the lift distance and what size trailer they will fit. The Ultra-Fab Power Twin II Electric Stabilizer, part # UF39-941707, has a 22 inch lift capacity and is designed to fit trailers with a frame with between 42 and 77 inches. The Ultra-Fab Power Twin II Electric...

  • Can the Ultra-Fab Power Twin II # UF39-941705 be Used to Lift or Level a Travel Trailer
  • The Ultra-Fab Power Twin II # UF39-941705 were designed as stabilizers and not actual lifting jacks. You could, however, potentially install Electric Ground Control TT Automatic 5-Point Travel Trailer Leveling System # LC672136 which can do lifting in order to level the trailer. This system was previously only available for 5th wheel trailers but they came out with a travel trailer version recently. The greatest thing about this system is that it will level the trailer automatically....

  • Rear Electric Stabilizer Jacks for a 12,000 Pound 5th Wheel Trailer
  • Ultra-Fab has a couple of options that could work for you. They are versatile and each is rated for 6,000 pounds total. This is important because stabilizers are not meant to lift weight, just support and level the trailer. It is possible that the weight where you place the jacks will exceed 6,000 pounds so you have to be careful of where you place them. Behind the rear most axle, as far back as you can go, would be ideal. For a model with 22 inches of lift use # UF39-941707 and for...

  • Recommended Travel Trailer Automatic Electric Leveling System
  • For a travel trailer, there is now an automatic leveling system similar to the # LC358590 for 5th wheels.

  • Comparing Ultra-Fab Replacement Landing Gear Motor/Gear Assemblies UF39-750009 & UF17-750007-003
  • The two Ultra-Fab replacement motor and gear box assemblies you referenced, parts # UF39-750009 and # UF17-750007-003, are indeed very similar. These parts differ in their intended use. Part # UF39-750009 is intended for use on the Power Twin II Electric Stabilizers # UF39-941705 and # UF39-941707. Part # UF17-750007-003 is intended for use on their landing gear set # UF17-943010.

  • Electric Stabilizer Jacks for a 2018 Dutchmen Endurance 3556
  • We have not yet test fit the Lippert Components High-Speed Power Stabilizer Jack part # LC298707 on a 2018 Dutchmen Endurance 3556 therefore, in order to determine fit you will need to measure the distance between the two frame rails on center. They will need to be 68-11/16" apart or close in order for this system to work for you. If they are not then the only option we have is the Ultra-Fab Power Twin II Electric Stabilizer part # UF39-941705 which will fit trailers with frame rails between...

  • How Does Ultra Fab Stabilizer Jacks UF39-941705 Attach to Frame
  • You can run the mounting bolts of the Ultra Fab Stabilizer Jacks # UF39-941705 up from the bottom or down through the top. Whichever works best. You wouldn't want to submerge the switches under water but they will easily survive rain and normal outside weather. I attached a picture that shows the setup attached to a trailer frame for you to check out.

  • Availability of Auto Leveling Scissor Jack for a 2017 Keystone Passport Elite
  • We do not currently offer any automatic leveling systems for you to use on your 2017 Keystone Passport Elite, however we do have another option.

  • Can Stabilizer Jacks for RVs Also Lift Trailers
  • Typically stabilizer jacks and leveling jacks are the same thing. The Ultra Fab part # UF39-941705 can do both as well. It can lift up to 30 inches from where the jacks are mounted on the trailer. When the jacks are at their max height they have a capacity of 6,000 lbs and when they are at half height (15 inches) they have a 3,000 lb capacity. You should note that these jacks aren't designed to lift the tires off of the ground. Their capacity is for the weight of the trailer, but not...

  • 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...

  • Whether or not you will need two of the Ultra-Fab Power Twin II Electric Stabilizer Jacks # UF39-941705 on your Jayco Trailer, or just one mounted to the rear, will ultimately come down to your personal preference along with what you currently have installed at the front. If the front of your trailer is supported just by a jack, then the closer you get to the front the more likely it is to sway and for you to experience instability. Most likely, using just one unit will be enough to...

  • What Gauge Wire Is Required To Use When Installing Ultra-Fab Power Twin II Electric Stabilizer
  • Per the installation instructions for the Ultra-Fab Power Twin II Electric Stabilizer with Dual Motors, part # UF39-941705, 10 gauge wire like part # 10-2-1 should be used, or it will void the warranty for the stabilizer. We do offer the # 10-2-1 wire and you can order it by the foot. In the instructions it also states that for any runs longer than 15 feet, 6 gauge wire should be used. I have attached the installation instructions for the # UF39-941705 you can take a look at.
