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.

  • 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...

  • 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...

  • 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...

  • 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.

  • etrailer Square Jack w/ Footplate to Replace Ram Side Wind Jack
    Thanks for the pictures! It looks like you have a Ram side wind jack and we do sell replacement parts for it. The jack you were looking at would be a great replacement for it if these parts do are not what you are looking for. The etrailer Square Jack w/ Footplate item # MJSQ-2500B is a bolt on, drop leg, sidewind jack. It has a 29-1/8" Lift and like your Ram jack is rated for 2,500 lbs. The rust-resistant, clear zinc finish protects against rust and corrosion caused by contact with water,...

  • Recommendation For Replacement Trailer Jack For Four Winns Boat Trailer
    A solid replacement jack that I recommend is the Square Jack w/Footplate-Bolt On, Item # MJSQ-2500B. This item is a great marine jack that has a rust-resistant zinc finish and that is built to be flexible and durable. It has a lift capacity of 2,500-lbs, fits a frame height from 2 inches to 5 inches, and has a comfortable, grooved grip handle. If this will not work for you, send me some more information like weight capacity needed, mounting bracket dimensions, pictures, etc. and I will...

  • Replacement Boat Trailer Jack Non-Swiveling For Clearance Of HitchMate Boat Trailer Step
    The HitchMate Boat Trailer Step part # HE4036 should fit with a swing up jack depending on where you place the step. The retracted height of the Fulton Bolt-Thru Swivel Marine Jack - Bolt On - Sidewind part # FXP15L is 26" so you may be able to make both fit depending on where you want the step to be located on your trailer frame. If you still prefer a jack that does not swivel, I recommend etrailer Square, Fixed-Mount Marine Jack - Drop Leg part # MJSQ-2500B which has a 29-1/8" Lift...

  • 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"...

  • What is the Difference Between the Fulton HD50000101 and the etrailer MJSQ-2500B?
    Though these two jacks do look to be nearly identical, there is one fairly large difference, and one lesser of one as well. The large one being the weight capacities they can handle. The # HD50000101 is rated up to 5,000 pounds, whereas the # MJSQ-2500B is rated up to 2,500 pounds. So it is mostly the internals that are different, which is why they look like each other. The smaller difference is how the cranks attach to the jack. The # HD50000101 has a gear box, for the lack of a better...

  • Options For A Tongue Jack With Low Retracted Height For An ATV Trailer
    Hello George. I believe I understand what you are describing. I really cannot recommend modifying a jack in the way you described though. If you need something with a retracted height of less than 10-1/2" we do have a few options for you. One is the Square Jack w/ Footplate # MJSQ-2500B. This jack has a 7-1/4" retracted height. As far at the bolt on tongue jacks we offer, this will have the lowest clearance of all of them. The only downside is that this jack has a footplate and not a wheel....

The next closest option we have is the Fulton Fixed-Mount Marine Jack part # TJ12220301 which has a 1,200 lb capacity, can extend up to 15", and does not have a swivel feature. These will be the best options that we have to replace the Fulton XLT Bolt-Thru Swivel Trailer...

  • Recommended Trailer Jack With Shortest Retracted Dimension
    The etrailer Square, Fixed-Mount Marine Jack, part # MJSQ-2500B, you referenced is a fixed position jack. The jack leg would protrude below the level of the trailer tongue and would not be the flatter surface you said you are looking for. The closest to 1-1/2 inches you said you need is the Bulldog Rack-and-Gear Jack with Footplate, parts # BD018161 and # BD018520. This is a weld-on system with a 750 lb lift capacity, and measures 2-1/2 inches fully retracted. This jack has a lift distance...

  • 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...

  • Availability of Caster Wheel for etrailer Square Tube Jack
    We don't offer a caster wheel for the etrailer # MJSQ-2500B 2500 lb capacity jack you mentioned, mainly because the casters will limit the capacity of the jack because the capacity of the caster wheels typically top out at 1000-1200 lbs. What's the tongue weight of your trailer? If it's below 1000 lbs, you can use a trailer dolly like the Trailer Valet, part # TVXL2 for a 2 inch trailer ball or # TVXL25 for a 2-5/16 inch ball. These trailer dollies are meant for use on a flat surface that's...

  • 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...

The mounting bracket on the jack is at the very bottom of the outer tube so you don't have to worry about a swing-away but we do have the Fulton F2 Swing-Up Jack part # F1413230134 if you want a swing-away feature though you will pay more for this.

  • Can Handle on 2,500 Lb Square Jack - Drop Leg be Reversed
    The handle on the Square Jack part # MJSQ-2500B which is our version of the Fulton FHD2500/HD25000101 is not reversible. The jack is designed to be mounted on the outside of the frame so any other orientation would affect function. In regards to capacity, the jack has a 2,500 lb rating but this only corresponds to the tongue weight of the trailer. The tongue weight should only be around 10-15% of the trailer's loaded weight. It would be more than capable of handling a trailer your size.

  • How Much Grease Should Be Added to Square Jack with Footplate MJSQ-2500B
    The grease fitting on the Square Jack with Footplate part # MJSQ-2500B is just used for maintenance. I don't have an exact amount of grease to run through the fitting as there are too many variables but if you ever feel the jack getting harder to use you would just squirt a few pumps into the jack. It would also be a good idea to add a bit of grease before each season. The orientation of the jack does not matter when applying grease. I recommend the LubriMatic Mini Grease Gun Kit with...
