    • Drop leg: 15"
  • Combined weight capacity: 6,500 lbs
  • 1-Year warranty

Note: Landing gear is designed to stabilize a portion of your trailer's weight, not to support the full GVWR of your trailer. Do not use landing gear to lift your trailer or RV during tire changes or service work because doing so will exceed the capacity of the landing legs.

Stromberg Carlson's landing gear was designed with safety in mind. The motor, manufactured by Lippert, won't trip circuits or cause problems with the coach's electrical systems. In addition, the IP-rated switch will not spark, so it can be mounted safely in the bottle-gas area.

Convenience is also a hallmark of this product. An inner drop leg on each jack makes leveling easy by allowing the jack feet to reach the ground quickly and at varying heights, saving time and thus reducing the draw on the trailer's battery. The cage pins that secure the drop legs can be replaced with spring-loaded pull pins (LG-119113 - sold separately) that allow for single-handed operation. Large, rectangular, pivoting footpads are included, but you can use larger, 9-inch-diameter pads (LG-210475 - sold separately) instead if you often camp on soft ground.

This system and its parts were designed to be compatible with most of the other fifth-wheel landing gear on the market, including Atwood and Lippert. If you're replacing your old landing gear, you can install this set from Stromberg Carlson using your existing mounting hardware.

Video Transcript for Stromberg Carlson Camper Jack - Landing Gear - LG-4 Review

Today we're going to be taking a look at the Strombeg-Carlson Electric Landing Gear Set. This set is perfect for 5th-wheel campers. The electric-powered adjustment allows for nice, easy operation. It's going to feature the single-speed Lippert motor that has built-in safety features. The motor won't trip circuits or cause problems with the coach's electrical system, and it's IP-rated when it comes to the switch which is included. That means that it won't spark, so it can be mounted safely in the bottle-gas area of desired. Now each leg is going to come with a drop-leg, that's the insert located at the bottom that has the footplate attached to it.

Drop-legs are designed to minimize jacking time, and it's going to help to level the trailer on uneven ground. Those legs are going to adjust in 1" increments, and the cage pins are included that allow you to easily release the drop-legs. Each leg comes with a removable footplate, that's going to be attached with another pin located at the bottom of the drop-leg. The footplate is really nice to have, that's going to help spread out the applied weight and prevent sinking on softer surfaces. Those footplates are a rectangular design.

They're going to measure 5" wide by 8" long, and those can be removed and oriented the other direction too if you want. There's going to be a installation hole on each side of the inner tube there of the drop-leg to get that attached and installed in whatever orientation or position that you want. The unit's also going to come with a hand crank, this is going to allow for manual operation. The unit's made from a heavy-duty steel construction, it's going to feature protective finishes to keep the system safe from rust an corrosion. The gear box is housed in a corrosion-resistant aluminum body. The landing gear is designed to weld on to the trailer frame with the included weld-on brackets.

Now, I do want to point out that in order t make sure that your jacks are supported, whether they're being retracted or extended, so either way of operation, you want to make sure that one of your brackets is underneath one of the weld stops. Then you want to make sure that the other bracket is on top of a weld stop. The set's going to come with 2 jacks. You're going to get your gearbox and your motor. You're going to get your switch. Your going to get your footplates, cross shaft, hand crank.

You're going to get your weld-on brackets, all the necessary hardware, and all your necessary wiring. A few measurements I want to go over with you real quick. First thing we're going to talk about is the weld stop distances. These are important because you want to know if this is going to be a perfect match for the trailer that you have. What we want to do are two different measurements. We want to take a measurement from the top of one weld stop, so not the actual bracket, but the weld stop. From the top of one weld stop to the bottom of the other, is going to be 19.5". From the bottom of this weld stop to the top of the other is 21.5". Again, from top to bottom 19.5", from bottom to top 21.5". The leg length is going to be 33.5", and that's the outer tube length so from the bottom of this portion right here, so just that outer tube that black portion, to the top of the jack is 33.5". Then from the bottom of the footplate to the top of the jack is going to measure 37.5". Now this system's going to use a stroke length of 19-7/8", which gives it a height of around 57-3/8" when fully extended. Then that drop-leg is going to give an additional 16" of travel that can be adjusted in increments of 1". The combined weight capacity for this unit is 6,500 lbs. The outer tubes are going to measure 2.5" by 2.5", and your cross shaft is adjustable from 41" to 71". That's going to do it for today's look at the Strombeg-Carlson Electric Landing Gear Set.

I put them on they will lift the trailer by hand but motor can’t lift is there a strong motor for this you Customerservice said it would lift this trailer it is a Fleetwood terry 5th wheeler 511143

- LG-4

I purchased this landing gear to replace the RBW landing gear on a 1998 Mallard made by Fleetwood. Only one side of the RBW was bad, but I was unable to find parts to repair it. I had to weld new brackets to the legs to match the existing U brackets that were already welded to the frame of the 5th wheel. Everything went smoothly with the installation until I went to hook up the square tubing for the cross bar that ties the legs together. The tubing was about 8" too short to reach from one leg to the other. Luckily I was able to use the cross bars from the original RBW gear. I am not sure why the Stromberg Carlson cross bar was so short because my 5th Wheel is a standard width. Other than that it looks like a good product. 301638

was pleased with the service and shipping time. Have it half installed as it is raining now with a lake under the front. 598270

I have a 2010 Bighorn 3055rl and these jacks were an exact match to the failed jacks so installation was simply a reverse of the removal. All of the necessary parts were included for a full replacement. The quality seems similar to the originals. I hope they last longer and they should as I have changed how I operate them. In my opinion, they did not come with enough grease on them and that may also be part of the reason the original jacks failed. I put plenty of grease on these. 584430

- LG-4

Product was exactly what I needed. We only had to make one modification to the legs so that we did not have to weld in the new straps. Works perfect. I would love that it instructions would have shown the picture as if you were facing the equipment. 519498

Best way to go even if your just fixing your ecisting jacks. They have made many improvements to the motor and gear box. 498065

Ask the Experts about this Stromberg Carlson Camper Jack
Do you have a question about this Camper Jack?

  • Troubleshooting Landing Gear Not Lifting 5th Wheel
  • Any powered landing gear or powered tongue jack will draw less power as it legs descend down toward the ground and much more as soon as they make contact and encounter resistance. This is a normal occurrence. In the same way, any jack - even a manual hand-crank type - requires less power (or force) when lowering the trailer than when lifting it. The cause for your powered landing gear losing steam could be any of several possibilities. These include the trailer's battery not being rated...

  • Replacement Landing Gear for 2010 Open Range 5th-Wheel Trailer
  • For your 2010 Open Range 5th-Wheel Trailer, I recommend looking at the Stromberg Carlson Electric Landing Gear Set # LG-4. Each leg on this set is 33-1/2 inches tall and provides up to 19-7/8 inches of travel. It has a combined weight capacity of 6,500 pounds and the direct-drive motor will reduce strain on the jack for easy stabilization. To determine if this will fit with the brackets you already have welded to your trailer, you will want to take a measurement between them. The distance...

  • Troubleshooting Landing Gear That Retracts But Does Not Extend Properly
  • Sometimes landing gear will retract but not extend due to an issue with available trailer power. It takes more current to make the legs extend (when they are pushing against gravity) than when they are retracting, at which time the trailer's own weight helps to push the extended legs back in. You could have an issue as simple as a bad ground and/or loose power cables. This is easy to check and will cost you nothing. You can also do a bypass test on the switch to find out if the landing...

  • Replacement Landing Gear Follow Leg for 2003 Keystone Everest
  • We can get you un-stranded! The correct follow leg for your landing gear is going to depend on how long it is. If your leg measures 29-1/2" (see attached photo), you would need replacement # LG-179014, which can be used with most landing gear sets Atwood, Venture, and Lippert models. The same is true of replacement # LG-177201, which you would use if your leg measured 33-1/2". I've attached a link to a video review for you to take a look at as well.

  • Repair Parts for Venture VMC940RB 5th Wheel Landing Gear
  • In case you want to just service your existing Venture VMC940 5th wheel landing gear driver leg you can use gearbox # LG-179015. For a complete replacement lead jack use Replacement Lead Jack with Drop Leg # LG-179013 which is a universal fit that works with major brands. I linked a diagram with measurements so you can compare to yours. For a motor to convert the gearbox and leg to electric operation you can use part # LG-196308.

  • How Do You Determine What Landing Gear Is On Your Trailer?
  • If there isn't a brand name printed on a tag somewhere on the actual landing gear it is not easy to determine because they all look and function the same way. The nice part about that is that if you need to replace parts or complete systems they are fairly universal and just require the proper weight rating or style. I've attached a link to our page to assist. One help is to measure brackets welded to your frame. The distance between them will help in determining a correct replacement. If...

  • Replacement Landing Gear for 2011 Heartland Big Country 5th Wheel Trailer
  • If your landing gear is electric then it could just be a switch or the battery could be bad. Having the battery tested will determine if it is the problem. You can determine if the switch is the problem by applying power directly to the motor; if it works fine then it is likely a problem with the switch. A battery or switch replacement is a lot easier and less expensive than a whole new landing gear system! But if it turns out that it is neither a switch nor the battery then I agree...

  • How to Select the Correct Replacement Follow Leg for Fifth Wheel Landing Gear
  • In order to choose the correct replacement follow leg, you will need to know the manufacturer or model number, which should be visible via a sticker or stamp somewhere on the landing gear. The reason for this is there may be slight differences that cause imbalance if the landing gear legs do not match. So if you have Stromberg Carlson models # LG-2 or # LG-4 then the correct replacement follow leg would be # LG-177201. I have added a link to our page with each of our follow legs for...

Both legs have an overall height of 32" with an outer tube width of 2-1/2" and an inner tube width of 2-1/4". The total travel distance is 21" with a 16" drop leg travel.

  • Replacement for Broken Landing Gear on 2010 Open Range 399BHS
  • There is certainly landing gear which is going to work for you, though to get the correct one you'll need to measure the distance between the mounting brackets outside to outside. For example, the Lippert Electric Landing Gear Set # LC333964 measures 17-1/2" while the Stromberg Carlson Electric Landing Gear Set # LG-4 measures 19-1/2". I've added a link to our page with each of our available landing gear sets for you to take a look at.

Please note that this is designed for use with Stromberg Carlson landing gear # LG-1, # LG-2, # LG-3, # LG-4, or # LG-183708. It can fit with a lot of other brands like Atwood or Lippert but if you don't have this landing gear just let me know what you have and I can see if we have one that is compatible with...

  • Troubleshooting Landing Gear on Fuzion Toy Hauler That Will No Longer Lift Trailer
  • It sounds like the landing gear on your Fuzion Toy Hauler may have been overextended, which likely caused damage to the internal gears and screw. This "flopping" that you mentioned is essentially the unit trying to extend but since the internal components have been compromised, it is unable to operate properly, which is producing that extensive vibration and shaking on the leg and motor. Your best option at this point is likely to replace the entire system. I recommend taking a look...

  • I was able to find that the landing gear brand used on your 1996 Nash 5th wheel trailer was RBW, but this was the only information Northwood Manufacturing (maker of Nash trailers) could find. Unfortunately the RBW trailer product lines were dissolved several years ago, so finding replacement parts or repair kits will be virtually impossible.

The weld stops on these legs measure 17-1/2 inches apart outside to outside. The total length on the legs is 29-1/2 inches.

  • Troubleshooting Powered Landing Gear That Won't Operate Under Load
  • Thank you for clearly describing the issue with the motor on one of your landing gear legs. When a jack motor operates when there is no load on it but fails to operate when there is a load this usually relates to a loose power connection. Check both of your power leads to that motor to ensure that both ground and hot connections are absolutely tight. A weak ground will deliver some power but often not enough to lift. When a jack operates in the retract direction but not in the extend...
