How to Determine the Lift Capacity You Need in a Jack

A trailer jack lifts your trailer high enough at the tongue to allow you to couple it with your vehicle. Usually, your tongue weight is about 10-15% of your gross trailer weight (GTW). For example, a 10,000-lb trailer has a tongue weight of 1,000 lbs to 1,500 lbs. To raise the tongue of a trailer this size, you'd need a jack that can handle a static load of no less than 1,500 lbs. And, yes, it's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher capacity should operate more efficiently, allowing you to spend less time cranking and more time fishing.

  • Trailer Jack Solution for Trailer Tongue that is 6 inch by 3 inch
    That is a pretty tall trailer frame but we do have a solution Dan. You could use the part # HD50000101 unless you wanted a swivel option. Then I would go with a weld on style jack like the etrailer # TJD-7000S for a sidewind or the part # TJD-8000 for a top wind. Or if you wanted something that could swivel you'd want a pipe mount like the part # BD178203.

  • Trailer Jack to Avoid Tailgate Clearance Issues
    There are a few solutions for your tailgate to clear the jack on your trailer. I recommend to use a longer ball mount like # D-26, that would move the trailer back further away from the truck and give you clearance you need. If you know what size the hitch on your vehicle is, the rise or drop of the ball mount for your trailer, if you're using weight distribution or not, and the measurement from the center of the hitch pin hole to the center of the ball hole I can make the best recommendation...

  • Mounting Hole Size for A-Frame Trailer Jacks
    The mounting hole dimensions of A-frame jacks are a standard 3 inches apart on center, so you will need to weld your new jack on. I highly recommend the etrailer Round, A-Frame Jack # TJA-5000S-B, which has a 5,000 lb capacity and will give you 15" of lift. It has an outer tube diameter of 2-1/4" and sidewind handle; for a footplate you would want # JF-99. This jack has been highly praised by our customers. I've added links to video reviews of this jack for you to take a look at as well.

  • Recommended Maine Trailer Jack for a 2006 Mastercraft X-Star
    I have the perfect replacement trailer jack for your 2006 Mastercraft X-Star boat trailer. For this, I recommend using the Fulton F2 Swing-Up, Wide-Track Trailer Jack part # F1413050334. It has a 1,600 lb. capacity and can raise your boat trailer up to 8". As long as your trailer's tongue does not weigh more than 1,600 lbs. then this jack will work well for you. You will also want to use the Weld-On Mounting Bracket and Hardware for Fulton Swing-Up Trailer Jacks part # F500277 to use...

  • Will a Taller Drop Leg Fit Fulton 2.5K Square Fixed-Mount Marine Jack FHD2500
    Fulton Square Drop Leg for Stabilizer Jack, 29" Long Item # FSJ20324 by itself will be 24-3/4 inches tall from where it attaches to the jack to the bottom of the foot with the drop leg in the tallest position. It is essentially more than doubling the lift amount of Fulton Square, Fixed-Mount Marine Jack - Drop Leg - Sidewind - 2,500 lbs Item # FHD2500. However, because the drop link is so tall it will not be able to retract all the way into the jack leg it is attached to so keep that in...

  • Recommended Tongue Jack for 12K Sea Ray Sundancer
    I do have some great jack options for you and your boat but the jack does not need to be rated for the entire weight of the boat, at least directly. For example, a trailer jack rated at 2,500 lbs is more than enough for a 12,000 lb boat. The reason for this is that the jack only need to be rated for the tongue weight, which is usually about 10-15% of the loaded boat+ trailer weight. Therefore, if you had a 13,000 lb loaded boat and trailer then all you would need the jack to be rated for...

  • Position of Foot Plate on Square Jack w/Foot Plate # MJSQ-2500B
    The foot plate of the Square Jack w/ Footplate # MJSQ-2500B that you referenced can attach to the jack in either orientation. You can have the foot plate longways so that it's parallel with the direction of travel or perpendicular. I would agree that parallel like you mentioned would seem more logical since rolling forward or back would be more likely where you'd want the support.

    Thanks for the pictures! It looks like you have a Ram side wind jack and we do sell replacement parts for it.

    We don't have a repair kit for that jack. Since it sounds like the screw is damaged and the handle is already broke it's time for a new jack. The etrailer jack part # MJSQ-2500B would be a great replacement for this.

  • Brainstorming Sidewind Trailer Jack for 2 Inch Receivers On Cargo Trailer Corners For Stabilization
    Interesting. We don't have that specifically, but there are a couple of routes you could go. Most trailers will use the Scissor Stabilizer Jack - 18-3/4" Travel - 2,500 lbs - Qty 1 # TJSC-24 for stability in the corners so you could mount a receiver shank to that and use # TJSC-24-HD as a sidewind crank. It sounds like you were picturing more of a trailer tongue style option, so you could use a jack like the etrailer Square Jack w/ Footplate - Drop Leg - Bolt On - Zinc - Sidewind - 29-1/8"...

  • Replacement For 2,500 lb Square Jack
    There is not a replacement handle for the older topwind Fulton Magnum Series jacks, so you'll need to replace it. Since yours is a 2,500 lb capacity a good option would be the 2,500 lb Square Jack w/ Footplate # MJSQ-2500B. This fits trailer frames up to 3" wide x 5" tall and has a total of 29-1/8" of lift. If those aren't the right specs for your needs I have also added a link below to our entire selection of jacks for you to take a look at.

  • Recommended Side-Mount Trailer Jack for Camper Trailer to Improve Tailgate Clearance
    I understand your tailgate clearance need but I do not recommend going without a tongue jack on your camper trailer. What you might do instead, to both improve your tailgate clearance and retain the safety and utility of a trailer tongue jack, is install a different type of jack, a side-fame-mount type, in place of the A-frame tongue jack. The stabilizer jacks on your camper are designed to support weight but would not take kindly to the bumps they might receive as you back your tow vehicle...

  • Recommended Trailer Jack For a Home Made Trailer With Wheels For Maneuverability
    I recommend checking out the Xtreme Off-Road Swing-Up Trailer Jack w/ Dual Wheels # ORJW750D for your homemade trailer. This jack allows you to swing the jack which will get the wheels further off the ground when not needed unlike the Square Jack w/ Footplate # MJSQ-2500B you found. We do not have a wheel kit for this jack. While we do not have a trailer jack with pneumatic tires the Xtreme jack above includes steel wheels with rubber tires for durability.
