Expert Answers about Ultra-Fab Products

  • Trailer Ball Height to Increase Tongue Weight to Help with Sway Control on a Single Axle Fish House
  • You should have the hitch ball height set so that the trailer tows as level as possible behind your pickup. If there is a setting that goes between slightly higher than level and slightly lower than level, opt for the slightly lower setting, when the trailer is sitting on the trailer ball. An increase in tongue weight will most likely help with your sway situation. Adding weight in front of the trailer axles would be the best way to increase the tongue weight, just make sure you stay...

  • Replacement Electric Stabilizer Jack to Replace a Lippert Unit
  • The Ultra-Fab stabilizer jack # UF39-941602 is made by Lippert. If replacing the whole unit, which is what I recommend because there could be unseen damage beyond the damaged leg, you could still use the Ultra-Fab model. This one has a capacity of 3,200 pounds. We also have # UF39-941705 which has dual motors allowing you to level each side independently. It has a 6,000 pound capacity.

  • Availability of Replacement Motor for Lippert Stabilizer Jack
  • I spoke with my contact at Lippert and he said that based on your description it sounds like you will need to replace the motor on your Lippert LCI 113407 stabilizer jack on your 2011 Keystone Montana Mountaineer. Sometimes road spray gets inside the motor assembly which can damage the springs holding the commulator brushes causing them to rust. It also sounds like the semi tire tread may have damaged the motor. The part you will want is # LC138445. This part will come with complete installation...

  • Recommended Cargo Carrier and Hitch for Rear of Travel Trailer
  • We do not offer a bolt-on cargo carrier, but you could certainly use a hitch mounted carrier. The first step would be to install a hitch like the Curt # E-100. The hitch is compatible with 4 inch square bumpers, and offers a 350 lb tongue weight capacity, which means that the weight of the carrier used plus the weight of the gear carried upon it could weigh no more than 350 lbs. Because of the extended distance between the rear axle and the back bumper of the average travel trailer,...

  • Scooter Carrier and Hitch Recommendation for RV with 4 inch Square Bumper
  • If you would like a motorcycle carrier that will work on a motorhome, I recommend looking at the Ultra-Fab Motorcycle Carrier, # UF48-979033. We were informed by Ultra-Fab that it is okay to use this carrier on a motorhome or trailer. For a hitch to mount to your 4 inch bumper (assuming it is rated for the weight of your scooter and carrier), you would want the part # E-100. Curt requires the use of their stabilizer strap part # 18050 when using their hitch to carry a non-supported...

  • How to Pick Out Landing Gear for Trailer, Bulldog or Ultra Fab
  • In order to pick out a direct replacement for the landing gear on your 2007 Desert Fox 38U we would need to know the distance between the mounting brackets. Otherwise you could just have the brackets removed from your trailer by a qualified welder and then install the brackets that come with the Bulldog Tandem Landing Gear Set # BD500162. Either way this landing gear set would work well for you, you just might have to have the brackets of your trailer removed and then install the brackets...

  • Recommended Weight Distribution/Sway Control System for 3500-lb Camper Trailer
  • Apart from the white-knuckle sway effects from sudden wind gusts and air blasts from passing semi trucks, there are some other basic considerations to help you decide if and when you need a sway control system for your trailer set-up. The linked article on weight distribution/sway control (WD/SC) systems may help you on this point. Although we do offer basic friction style sway control devices like # UF35-946204 and # 17200 that can help counteract trailer sway these are not going to...

  • Is Ultra-Fab Deluxe Electric Landing Gear Set # UF17-943010 Suitable for Heavy Equipment Gooseneck
  • The Ultra-Fab Deluxe Electric Landing Gear Set you referenced, part # UF17-943010, is suitable for use on both 5th wheel and goose neck trailers. This dual motor landing gear set has a combined capacity of 12,000-lbs so it will work fine on your goose neck as long as its fully-loaded pin weight does not exceed this 12K rating. Installation consists of welding on the hangers to the front of the trailer frame (below the overhang). You will want a certified welder to do this. Then you will...

  • Recommended Hitch Receiver For Jayco Travel Trailer And 4-Bike Rack Application
  • For your 2017 Jayco Jay Flight SLX 267BHSW travel trailer, I recommend the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403. This is a very nice weld on option adjustable from 47-1/8 to 77 inches. For a bolt on option, I recommend the Curt Adjustable Width Trailer Hitch Receiver for RVs, 22" to 72" Wide # 13703. The Curt model recommends the use of stabilization strap # 18050. The weld on options are nice because they don't require any drilling into your frame, but...

  • Dimensions of the Square Tube on the Ultra-Fab Deluxe Electric Landing Gear Set
  • The square tube on the Ultra-Fab Deluxe Electric Landing Gear Set, # UF17-943010, measures 2-1/2 inches x 2-1/2 inches and it measures 24-1/4 inches tall. The foot plate measures 8 inches long x 5-3/4 inches wide. I have attached a photo showing these dimensions.

  • Troubleshooting Landing Gear that Clicks and Will Not Lower on 2006 Keystone Montana
  • The correct replacement landing gear legs are the Lippert Replacement Lead Leg for Kestone Montana 5th Wheel # LC178653 and the Replacement Follow Leg # LC178652. If you need a new cross shaft you can use the Lipper Components Universal 5th Wheel Landing Gear Cross Shaft Kit # LC334096. You mentioned that you've already replaced the motor and switch, # # LC217884, and the gear box # LG-179015. Since you've already replaced these components, it sounds like your landing gear is not getting...

  • Electric Stabilizer Jack Recommendation for a 2012 Keystone Outback Travel Trailer
  • We have several electric stabilizer options for you to choose from. First, there are the Ultra-Fab Power Twin II Electric Stabilizers, # UF39-941705, UF39-941707 and UF39-941600. Then we have the Ultra-Fab Rear Electric Stabilizer, # UF39-941602. You would need the proper stabilizers based on the width of your trailer frame and the lift height that your trailer will require. Most likely a pair of the # UF39-941600, Electric stabilizers that you referenced, would work for your...

  • Recommended Electric Power A-Frame Jack for a 28-Foot Jayco Travel Trailer
  • Yes. A 3,000 pound electric jack will work just fine. Based on your trailer weighing 7,500 pounds loaded will equate to your tongue weight between 750-1125 pounds. Although you can choose a 2,500 pound (see link attached) electric jack, I would highly recommend the Stromberg Carlson # JET-3555 (white) or # JET-3755 (black) as they are rated at 3,500 pounds. I think you will really like the price point! I have also included an FAQ for you too.

  • How to Carry a Generator on an A-Frame Travel Trailer
  • I have a great solution for you that will not require adding a hitch to the trailer so you won't have to move the spare tire and mount. Take a look at the Stromberg-Carlson cargo carrier # CC-255. It mounts at the front of an A-frame trailer frame and has a 300 pound capacity. It holds the generator up above any propane tanks, jack, or other items already present at the front of the trailer. This unit will also be more stable than a hitch and cargo carrier mounted at the back of a trailer.

  • RV Hitch and Cargo Carrier Recommendations to Allow Transporting 190-lb Generator
  • We offer two varieties of trailer hitch receivers for use on RVs, the bolt-on 4-1/2 x 4-inch-bumper-mount type such as the Ultra-Fab 2-Inch Motor Home Trailer Hitch Receiver # UF35-946401 that you referenced, and the higher-capacity multi-fit frame-mount type like the Curt # C13701. I suggest you check your RV owner's manual for any guidance or restrictions regarding the use of bumper- or frame-mount hitches and accessories. For safety and capacity I suggest a frame-mount hitch for your...

  • Recommended Bike Rack For Use on Pop-Up Camper
  • The bolt-on trailer hitch receivers for use on the bumpers of RVs and trailers, such as the Ultra-Fab # UF35-946402, require that the bumper be continuously welded across its entire length and that it be a 4 x 4-inch size. Since this will not work with you application I suggest a towing rack that slips over your ball mount. This will place your rack in front of the trailer rather than behind it. The link provided will show you all such towing-type bike racks which are offered in 2, 3...

  • Recommendations For Skid Rollers on 39 Foot Forest River 5th Wheel
  • I would recommend the Ultra-Fab Skid Wheels, part # UF48-979013, for your 39 foot Forest River 5th Wheel. These larger 6-inch diameter wheels will bolt onto the frame of your 5th Wheel to help prevent the tail from dragging. The longer the RV/5th Wheel, and the greater the distance between the rear of the RV/5th Wheel and the back axle, the greater the forces the skid wheels will have to deal with. This is why the larger, stronger skid wheel like those used on the Ultra-Fab # UF48-979013...

  • Will Ultra-Fab Landing Gear Fit a 2008 Weekend Warrior 5th Wheel Trailer
  • There may be s ticker or something in the literature for the trailer that states the capacity of the existing landing gear. You would want to match or exceed that capacity with the new landing gear. Provided the frame has steel vertical frame members, most likely it does and that is where the old landing gear is attached, you will attach Ultra-Fab landing gear # UF17-943010 in the same places. The brackets that attach to the trailer will need to be welded on. Welding should be done by a...

  • Replacement 5th Wheel Landing Gear for 2006 Weekend Warrior 35-Foot 5th Wheel
  • When it comes to jacks, winches or landing gear we suggest choosing a product with more lifting capacity than you need. In the case of 5th wheel landing gear the extra capacity means the jacks will have to work less hard to do their lifting and may have a longer working lifespan as a result of not being operated near their limit. The Ultra-Fab landing gear you referenced, part # UF17-943010, have a high 12K lift rating, a 38-inch lift height and a travel rate of 15 seconds per inch....

  • Recommended 2-Inch Trailer Hitch for Use on 2016 Keystone Hideout Trailer
  • We have both bolt-on and weld-on 2-inch frame-mount hitches available for your Keystone Hideout trailer that can be seen by clicking on the included link. All of these have a square cross tube, 2-inch receiver opening and are rated for either 3500-lbs or 5000-lbs gross trailer weight. In your application I recommend one of the higher-capacity hitches. You'll want to check your trailer's frame width for a proper fit. Hitch # UF35-946403 from Ultra-Fab is a bolt-on type that fits frame...

  • Easy Way to Lift Tandem Axle Wheel Off Ground to Change Flat Tire
  • The Ultra-Fab Ultra Scissor Jacks # UF48-979002 can be used on up to 6,500 lb trailers as stabilizer jacks, but they do not have the lifting capacity to actually lift a 6,500 lb trailer off the ground. Attempting to do so could damage the jack and potentially damage your trailer as well as hurt someone attempting to change a tire with this jack. For a tandem axle trailer a much easier way to lift a trailer to change the spare would be to use the part # AM3620 instead. I attached a review...

  • Where Does the In Line Fuse Holder Get Installed on Ultra-Fab Electric A-Frame Trailer Jack
  • On the Ultra-Fab trailer jack # UF38-944017 the in line fuse holder will be cut in half and spliced in along the power wire. Ultra-Fab makes the following statement: The Fuse Holder can be installed by means of either crimping or soldering the connections. For convenience the Fuse Holder should be installed near the power source. Cut red wire in half, connect one end to the end of the black wire from the jack and connect the other end of the red wire to the positive post of the battery.

  • Solar Powered Roof Vent Recommendation for Cargo Van to Exhaust Hot Air
  • Based on what you described your best option will be the Ultra-Fab Solar-Powered Plumbing Vent # UF53-945001. This solar powered vent will install on the roof of your cargo van and will work to remove the hot air at the top of your van's interior as long as it has access to sunlight. I attached a review video for more info for you to check out as well.

  • How do the Ultra-Fab Stabilizer Jack Attach to RVs
  • The Ultra-Fab Power Twin II Manual Stabilizer for Trailers and RVs # UF39-941704 that you referenced is designed to be bolted on with the included mounting hardware. The difference between the # UF39-941704 and the # UF39-941705 is that the # UF39-941705 comes with dual 12 volt motors to raise and lower the legs of the stabilizer jacks. Whereas, the # UF39-941704 that you referenced require manual operation that includes cranking a jack handle.

  • Will Ultra-Fab Power Twin II Manual Stabilizer Fit a 2003 Keystone Cougar 5th Wheel Trailer
  • The frame width on your 2003 Keystone Cougar 5th wheel trailer will need to be between 48 and 80 inches (measured from the outside of the frame on one side to the outside of the frame on the other side) in order for the Ultra-Fab Power Twin II Manual Stabilizer, # UF39-941704, to fit. The stabilizer has L-shaped brackets that fit on the frame and will be bolted into place. It is a straight forward installation and the average do-it-yourselfer should have no problem performing the installation....

  • Can an Enclosed Trailer be Towed Behind a 5th Wheel Trailer
  • Towing one trailer behind another trailer is illegal in many places so the first thing you are going to want to do is check the laws where you will be traveling. It is also just not a good idea because it is not safe. The likelihood of jackknifing and a bad sway condition is greatly increased plus there is a lot more momentum pushing you forward. If installing a trailer hitch on the 5th wheel I strongly recommend a frame mounted hitch, not a bumper mount hitch. The bumper mount hitches...

  • Replacing Scissor Jacks with Frame Mount Stabilizer Jack on a 32 Foot 5th Wheel Trailer
  • The advantage that the Frame-Mount Stabilizer Jack, # UF39-941707, gives you over scissor jacks, like part # UF48-979002, is that it is one unit mounted across your trailer frame providing more stability. This stabilizer jack can be adjusted from either side like your scissor jacks to accommodate for surfaces that are not level.

  • Solutions for Towing Forest River Roo Travel Trailer and Carrying Bikes Simultaneously
  • There are a few different options that might work for you. A towing bike rack can be a good option depending on the tongue weight of your camper. The Swagman # S64600, used in conjunction with an extra long ball mount like # 2736 or # D-28 (choose the one with the rise or drop you're needing) might be a good option, but keep in mind that the tongue weight capacity of the hitch would be reduced by the weight of the rack and the bikes. For instance, say the three bikes weigh 100 lbs. The...
