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. .

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

The product itself is a good product but the packaging for shipment is very bad. I received mine and the box was badly torn apart and tapped back together. I was missing multiple pieces and had to wait until the replacement pieces arrived. Customer service was very helpful with resolving this problem within minutes. 119770

Scary at first, but following directions, it bolted right onto the frame, used a floor jack to hold it in place while attaching. Wiring was uncomplicated, except for figuring out where to route the wires. works fine, I am a happy camper! 340760

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

i find these easy to operate. installation took a little time as i had to works underneath the camper. i have discovered, the middle of the jacks flex when leveling. i have some heavy angle iron, i am going to reinforce them. before i do that operation, i am going to add more bolts, that may be the simple solution. overall, excellent product. 481698

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

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

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

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
$2,263.09
. 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.

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

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

Very happy with the quality of this stabilizer jack!! I currently only have the jack installed on one end of our toy hauler and you can feel the difference in how stable the camper is on one end compared to the other end that still has the scissor type jacks. I will definitely be purchasing a second one!! 280015

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

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.

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

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

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

This product is awesome and has made a substantial difference in the stability of our camper! We have a 32' travel trailer and the factory jacks are sad and could feel every movement of the kids. This has taken away 90% of the movement that we were having before. If you are not handy plan on having someone install this for you. It's not hard to do but if you don't have some tools for the job you will struggle. It took about 4 hours total to install. 529220

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

  • 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...

  • How to Remove Stabilizer Jacks From a Travel Trailer
  • There are only 2 ways to install a jack on a trailer; by bolting it on or by welding it on. A simple bolt-on installation could very well be removed at home but you will need to make sure that whatever jack you decide to replace it with is installed correctly for safety. If it is welded on you will need to find a qualified welder to remove the jacks. If you have scissor style stabilizer jacks like the Lippert Scissor Stabilizer Jacks with Handle # LC285344, then we do offer a stabilizer...

  • Recommended Front Stabilizer Jacks For 2016 Forest River 265RLDS

  • Can Forest River R-Pod 180 Travel Trailer Use Electric Stabilizer Jacks
  • Smaller and lighter camper trailers like your R-Pod 180 typically do not have electric stabilizer jacks but instead use manual scissor type jacks. The main reasons are ground clearance, weight and power consumption. The manual scissor jacks typically need less ground clearance than electric ones and they add much less weight to your towing system. They also do not deplete precious battery power. Ram 2500-lb manual jack # TJSC-24, for example, has a retracted height of only 5-inches and...

  • How to Determine if the Ultra-Fab Power Twin II Electric Stabilizer # UF39-941707 will fit Trailer
  • The Ultra-Fab Power Twin II Electric Stabilizer # UF39-941707 that you referenced can fit trailer frames that are between 42 and 77 inches apart measured from the outsides. If you measure your trailer frame and it falls in that range this would work well for you. This would definitely help save your back some strain as it would allow you to stabilize your trailer by just activating the motors. I attached a review video for you to check out as well.

  • 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.

  • 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.

  • Will Lippert Electric Stabilizer LC337199 Fit a Frame Width of 43 Inches
  • I do have an option that will work with your 43 inch frame spacing but Lippert power stabilizer # LC337199 has a fixed hole spacing of 68-11/16 inches on center so it will not work.

  • 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 Stabilizer Jacks For 5th Wheel With Auto Leveling System
  • The Ultra-Fab 5th Wheel King Pin Tripod Stabilizer - Steel - 37" to 50" - 5,000 lbs # UF19-950001 are great for taking away the bounce/sway and can be used with your auto-leveling 5th wheel especially the bounce in the space over the king pin. The auto-leveling jacks are great for making your system level, but are not any different in stabilizing than any other jacks. The nice feature is that stabilizing is easy once level because it is simply adding support to remain level. If you...

  • Can Lippert Ground Control be Used on a Travel Trailer

  • Electric Stabilizer Jack Recommendation for a Trailer that Sits 23 inches from the Ground
  • You are correct in how to measure the lift of the stabilizer jacks. The distance is from the ground to the trailer frame when the trailer sits level. I would recommend you go with the 30 inch lift version of the Stabilizer Jack part # UF39-941707 that you referenced. For that you would want the Ultra-Fab Power Twin II Electric Stabilizer with Dual Motors # UF39-941705.
