Expert Answers about Trailer Jack


  • How to Pick Out the Correct Rated Jack for a Trailer
  • The capacity for our jacks based on how much tongue weight your trailer will see. For example the Pro Series Snap-Ring Swivel Marine Jack # PSEJ10000101 has a capacity of 1,000 lbs. If you trailer has less tongue weight than 1,000 lbs this jack would work well for you. If you are unsure of your tongue weight check out the FAQ article I attached determining tongue weight.

  • Can a 4,700 Pound Boat Trailer be Moved without Using a Motorized Trailer Dolly
  • You could probably move the boat and trailer if it was on level ground but up an incline would be difficult. The tongue weight of a boat trailer is normally lower compared to a utility trailer with the same gross trailer weight. This is because the rear of a boat is heavier than the front. If the tongue weight of your boat does not exceed 500 pounds you could use the Trailer Valet, # STC-V211. This is a jack and trailer mover in one. It has two speeds for easy moving of the trailer. It also h

  • How to Pick Out a Trailer Jack for a Boat Trailer
  • The best way to pick out a jack is to pick out one that has enough capacity to handle the tongue weight of your trailer. Typically, tongue weight is 10-15 percent of the total weight of the trailer. So lets say your boat and trailer weight a total of 10,000 lbs. Most likely you would have a tongue weight of 1,000-1,500 lbs. Without knowing your tongue weight but knowing the weight of your boat I think a 2,000 lb jack like the Bulldog Round Jack part # BD151443. Review video attached. or a foo

  • How Landing Gear Jacks are Connected to Fifth Wheel
  • The outer tube of the landing gear is attached to the fifth wheel frame via some frame clamps. The clamps themselves are usually welded to the trailer frame, and bolted clamps hold the outer jack tube in place. The inner tube of the jack will extend and retract, raising and lowering the front of the fifth wheel. The diagram I provided might make it a bit more clear for you.

  • Will Atwood Landing Gear Replacement Gear Box Fit a Venture Landing Gear Set on a 5th Wheel Trailer
  • It is possible that the gear box for Atwood landing gear, # 75054SP, will fit your Venture landing gear. However the only way to know for sure is to try it out because they have not been tested together. It is likely they will work together but I cannot promise that they will. A more likely fit is the Stromberg-Carlson gear box, # LG-179015, because both landing gear sets are actually made by Lippert. This one will fit Atwood landing gear so it is likely that either one will work. It is al

  • Can Electric Landing Gear be Installed on a Gooseneck Horse Trailer with Living Quarters
  • You can install the Ultra-Fab electric landing gear # UF17-943010 on your gooseneck trailer provided that there is somewhere at the front of the trailer they can mount to. I have included a link to the installation instructions for you so you can see how they install and compare it to your trailer.

  • Is Trailer Valet Trailer Jack # STC-V211 Suitable to Move a 22-foot Boat/Trailer on Concrete Surface
  • Considering that boat trailers are typically light at the tongue end (most weight being at the rear where the motor is) the Trailer Valet # STC-V211 should be fine for your application. Since you will be using the Trailer Valet on a smooth level concrete surface with no grade, its 500-lb tongue weight capacity and two-speed hand-crank operation should be fine for making tight maneuvers. I have linked a review video to illustrate its features.

  • Will Fulton F2 Trailer Jack # 1413250334 Fit an Industry Standard A-Frame Trailer Coupler
  • Yes and no. You would likely be able to mount the Fulton jack # F1413250334 on an industry standard 3 inch hole spacing. However, this jack has a unique shape, it is not round. It is a hexagon, and is not likely to fit in a standard A-frame hole. It is designed to fit a specific coupler, # F44305F0317.

  • Stromberg Carlson Electric Landing Gear Jack Recommendation for a 2003 Cherokee 295L 5th Wheel
  • I think I have a better solution for you. I think the Stromberg Carlson Electric Landing Gear Set part # LG-1 would be a better match for your 2003 Cherokee 295L 5th Wheel trailer. If you check out this jack you will see that the amount of jack and motor that is above the top mounting bracket is considerably less than the # BD500161 that you referenced so it should work well for you as long as its 6,000 lb capacity would be adequate.

  • How Does Fulton Bolt-Thru Swivel Marine Jack Mount to a Trailer
  • Fulton jack # FXP10W0301 is meant to bolt to a specific bracket, # P9012-00. It bolts through the center. This bracket measures 4-1/2 inches by 4-1/4 inches and is meant to be welded on. The holes on the outside of the bracket are to hold the jack when it swivels. They are 3 inches apart on center.

  • Trailer Jack and Dolly Recommendation for a Hi-Lo Trailer with Limited Tongue Space
  • The Trailer Valet Jack, # STC-V211, takes up 7-1/4 inches of the frame rail and it can mount to any trailer frame rail up to 2-3/4 inches wide and up to 6 inches tall. Since you only have about 6 to 6-1/2 inches available, this may not work for you. We do not carry any other jacks that function like the Trailer Valet, but another jack that you may be interested in is the Fulton Bolt-Thru Swivel Marine Jack with Dual Wheels, # FXPD15L. This jack has a slightly shorter lift height of 12 inches

  • Will a New Atwood 5,000 Pound A-Frame Trailer Jack Fit in Place of a Vintage Atwood Jack
  • You could likely remove the old jack and drop the Atwood jack # AT80391 in its place. But first, some measurement. Atwood jack # AT80391 has an outer tube diameter of 2-1/4 inches. And the mounting holes are 3 inches apart on center. Compare this to your existing A-frame trailer jack to confirm fit.

  • Will a Fulton Swivel Trailer Jack Fit in Place of a Shelby Swivel Trailer Jack
  • You do not necessarily have to change your order. In the even that the Fulton jack, # FTJ120W0301, is not a fit for the weld-on Shelby bracket, the Fulton jack does come with its own bracket that you could have welded on by a qualified professional welder. The holes on the Fulton jack that allow it so swivel are 3 inches apart on center. This should be the same on your Shelby jack if it is indeed the same as # 5876A8. The issue is the way the jack attaches to the mounting plate welded to

  • Sidewind Swivel Jack Recommendation for a 2014 StarCraft Camper Trailer with 700 lb Tongue Weight
  • I think your best option is going to be the Fulton F2 Swing-Up Jack with Footplate, # F1413230134. Like the other Fulton F2 jacks, it does have a higher price point, but it is one of the highest quality jacks on the market. Also, it is the only bolt-on swivel jack with a sidewind crank handle and a foot plate that we offer at this time. This jack was designed to fit 3 inch wide trailer frames, so you will want to use a 1 inch spacer to take up the gap for the u-bolts. The mounting plate can

I went out into our warehouse and pulled one to measure the dimensions of the mounting flange and I believe it would work for you since you said you needed 3 inches up and down between the mounting holes.

The nut is a 1/2 inch nut and the bolt is 1-1/16 inches long. The 4 holes for the swivel pin are 3 inches apart on center. I believe this is the jack you need. I have linked a video review for you.

  • Is the Stromberg-Carlson 3500 Pound Electric Trailer Jack Water Proof
  • The Stromberg-Carlson trailer jack # JET-2500 can get wet as far as rain or maybe some splashing water. But it is not designed to be submerged. The switches are water resistant but not water proof. For something to be considered as water proof it has to be able to be submerged under water for a certain period of time and still operate like normal. None of the electric jacks we carry should be submerged under water. If your trailer jack would routinely get submerged under water then I recom

  • What are the Handle Dimensions on Pro Series 5k Side Wind Trailer Jack
  • I went out to the warehouse and pulled the Pro Series trailer jack # PS1401600383 to measure the handle. I have included a video showing the measurements I took. The overall height of the handle is about 7 inches. From the jack tube to the end of the handle it sticks out 5-1/2 inches. From the End of the handle to the vertical part of the handle it measures 4-1/4 inches. From the top of the jack to the top of the handle when it is sticking straight up it is 4-5/8 inches.

When I told him of your concerns due to the issues with your current electric jack, he explained that the only area that moisture could possibly enter the housing is through the access cap. Removing the cap allows you access to override the system should you ever need to operate the jack manually. In this case, once you have removed the cap, he wo

  • Inner Tube Diameter of Bulldog # BD150415 Sidewind Jack for Genie Basket Lifts
  • According to my Bulldog representative, the inner tube of the # BD150415 jack has a 2 inch outside diameter and a 1-3/4 inch inside diameter. Keep in mind that in many cases the caster wheels are rated lower than the jack itself. Therefore, if you use a caster wheel like the # PS1400750340 that's rated at 1,200 lbs, the weight capacity of the jack will be reduced to 1,200 lbs.

  • How to Lubricate the Bulldog Round Topwind Trailer Jack # BD1701480317
  • There are two ways you can lubricate the Bulldog Round Topwind Trailer Jack, # BD1701480317. If the jack can be removed from the trailer, you can hold the jack upside down and apply a spray lubricant inside the inner jack tube. This will allow the lubricant to run down the screw and you can simply extend and retract the jack a few times to make sure the lubricant makes good contact with the inner screw and bearings. The second method would be to remove the bolt holding the handle to the jack

  • Which Capacity Jack for a 2002 Viking Pop-Up Camper
  • The capacity of the jack you choose needs to be greater than the tongue weight of the fully loaded and ready to tow trailer. I have linked you to an article that explains some methods of determining your trailer tongue weight. It's a good practice to overshoot the capacity quite a bit over and above the trailer tongue weight, if possible. Leaving plenty of cushion will mean that the jack will be easier to crank and will last longer. The Fulton # F1411300301 you referenced has a 1500 lb capaci

  • Holland Drop Leg Trailer Jack part # 48000 Recommendation

The 48000SL is spring loaded, thats what the SL stands for, which means that the inner leg will automatically raise up when the pin is pulled out. The # 48000 uses a cam lock style inner leg mechanism, other than that the jacks are identical and the # 48000 would install on your trailer easily and work well for you. We do n

I was able to find that your 2014 Forrest River Cherokee Vengeance 377 can have a gross vehicle weight rating (GVWR) of up to 18,000 pounds. This is the maximum allowable weight of the fully loaded vehicle. For 5th wheel trailers like yours the tongue weight is usually 20 to 25 percent of the GVWR.

  • Recommended Power Jack for Travel Trailer With 500 lb Tongue Weight
  • Although the jack you referenced would work well with the amount of weight you mentioned, when choosing a jack I always recommend overkill. Choosing the highest rated jack you can find will mean the jack will not need to work so hard. This means the jack will lift the trailer more quickly and will last longer. I really like the Husky Brute 4500 lb capacity model, part # HT87247. The jack provides some unique features, like ball-bearing operation for smoother and easier lifting and less power

The Pro-Series Jack that you mentioned # PS1400950376, only has a lift capacity of 10,000 pounds, and a static capacity of 12,000 pounds. Your trailer exceeds the capacities of the jack.

A handle or motor turns the gears that turn the screw to raise or lower the jack leg. There could be a roll pin in the shaft of the motor that engages the gears that is missing but you would have to take apart the jack to find it.

  • Is it Required that a Swivel Jack Be Fully Retracted Before Towing
  • Well since this jack can fold up for storage you would not need to fully retract it before you can tow. I have had trailers with similar jacks and found that I could just crank the jack up until the wheel comes off of the ground and then pull the pin in the jack and rotate it 90 degrees and be done with it. There's no reason you would have to fully retract this jack to use it. A 3 to 1 ratio might make for difficult cranking as well since you wouldn't have the same leverage over the tongu

  • Swivel jacks do not work well with A-frame trailers, so a swivel jack would not be a good choice. Your best bet would be to stay with an A-frame jack. I would recommend finding the jack with the lowest possible retracted height. For instance, the Pro Series # PSEA20000103 you mentioned has a retracted height of 8 inches, which would be the distance between the bottom of the jack tube and the mounting bracket. The Pro Series # PS1401000303 has the same 2000 lb capacity as the jack you mentione

Going higher than that will not benefit you at all since the internal breaker on this jack is rated for 35-amps. You are likely blowing fuses because, when this jack is under a load, it can pull around 30 amps. If a 35 amp fuse continues to blow, then I would suspect a short somewhere on the power wire.

Should you lose power, there is a manual adjustment on these landing gears. I have attached a photo that shows where the included tool is inserted. As the photo shows, a ratchet is then attached to the tool and allows you to adjust the landing gear manually. I have also attached a product review vid

  • Does Stromberg Carson Electric Trailer Jack have to be Lubricated
  • The Stromberg Carlson jack # JET-3500 is lifetime lubricated and should never require maintenance according to the manufacturer. In the event something got inside and caused the jack to misbehave you would have to take the jack apart and remove the foreign object. Otherwise keep the outside clean and the electrical connections in good working order and never overload or overextend it and you will get years of service out of it.

  • Can Scissor Jacks be Used in Place of Blocks on a Destination Trailer
  • You can use the Ultra-Fab Ultra Scissor Jacks, # UF48-979002, in place of blocks. In fact, many newer destination trailers use multiple scissor jacks. Keep in mind, these are stabilization jacks. They are not meant to raise the trailer, just to stabilize the movement. Blocks are commonly used because they are not only inexpensive and readily available, but they also provide more ground contact and zero movement over time. If you will be parking this trailer on grass or dirt for extended peri

  • Options for Powering Husky Brute Electric Trailer Jack
  • Adding a battery to power an electric jack is without a doubt the preferred method. The jack will operate more quickly, reliably and efficiently. It is possible to connect the power lead of the jack to the 7-way accessory power feed from the 7-way, but the jack will operate very slowly. If the weight capacity of the jack is exceeded, the wire feeding the 12-volt power to the 7-way could possibly overheat. To install the battery on the trailer, use the 12-volt feed from the 7-way to maintain

  • Would the Domar Stabilizer Jack # TJ01RT Work to Stabilize a Trailer when Loading a Mower
  • The Domar Stabilizer Jack # TJ01RT that you referenced can support 650 lbs individually. With a pair of these mounted on the rear of your trailer you should have enough capacity to load your 835 lb zero turn mower. I would recommend you chock the wheels of your trailer before load your trailer unhitched though. For wheel chocks you could get a quantity of 4 of the Valterra Wheel Chocks # 39323. Two for each side of the trailer.
