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.

  • Recommended Trailer for Bass Pro Pond Prowler 10 Foot Fishing Boat
    We have a really great option for a trailer for your 10 foot Bass Pro Pond Prowler boat, although the Malone trailer you mentioned has been discontinued by the manufacturer and is no longer available. Instead, which I highly recommend is an option from CE Smith: - CE Smith Multi Sport Boat and Kayak Trailer with Bunks # CE48810 When I looked up your boat it was just 130 lbs and 48 inches wide so it is going to be a perfect fit for this trailer and something you'll be able to easily use...

If you have preferences as to weight capacity/size/style let me know.

  • Are There 4.80R12 Tires With Powder Coated Wheels Available
    We don't currently offer a 4.80R12 radial tire and 5 on 4.5 wheel together, but we do offer them separately with part # TT48012C and # AM20151. This wheel has a white powder coating, if you'd prefer silver or black then you can click on the link below that will take you to our available options. For the spare tire mount I recommend the Fulton Hi-Mount Spare Tire Carrier # FSTC1000301. This carrier is designed to clamp onto trailer frames up to 3" wide x 4" tall. For the jack I recommend...

  • Recommended Jack With Wheel For A 2006 StarCraft Pop-Up Camper And How To Add Brakes To It
    If you're talking about having a trailer jack with a wheel to easily maneuver your trailer around when parking and coupling then I recommend the etrailer Round Swivel Marine Jack w/ Wheel # MJ-1206B. This trailer jack has a bolt-on installation that works with frames 2" to 4" tall. It has a 1,000lb capacity so it's well over the tongue weight of your 2006 StarCraft pop-up camper. It has 10" of travel to help make coupling to your Nissan Pathfinder easier. To add brakes to the trailer...

  • Replacement Jack for a 1996 Four Winns Boat Trailer
    We don't have any exact matches for what you have on your boat trailer so best option would be a new one that is similar like the # MJ-1206B which is a similar bolt on swivel jack with a sidewind handle.

  • Shortest Retracted Height Trailer Jack
    The Ultimate Trailer Jack part # 322-RDJ-2K has a retracted height of just 1-3/4" it has by far the shortest retracted length of any of the a-frame style jacks. If instead you wanted a swivel jack like what is more common on boat trailers the shortest option for that is the Pro Series part # MJ-1206B which is 13-1/2 inches from bracket to bottom of jack.

  • Replacement Trailer Jack for Shelby Model 5764A on Boat Trailer
    We offer weld-on and bolt-on trailer jacks that are similar to the Shelby 5764A jack you wish to replace but the jacks we offer are not exact replacements. We do have a jack that has a mounting plate similar to the Shelby mounting plate., It is part # FXP10W0301. This jack has a 1,2000 lb weight capacity and has a 10 inch lift. The plate used for this jack is part # P9012-00. I have attached a photo of the mounting plate with the dimensions. You can take the same measurements on your existing...

  • Recommended Side Mount Trailer Jack for Log Splitter Trailer
    I do have some options for you but I am not sure you are going to find a trailer jack with all of the exact features you are looking for. The minimum lift we offer is 10" and all of the caster wheels are 6" diameter. If you can make these two things work then we have plenty of options which I have attached a list of for you like the Round Swivel Marine Jack w/ Wheel part # MJ-1206B.

  • Recommended Replacement Jack For A Shelby 5854a Jack
    When it comes to replacing your Shelby 5854a trailer jack I recommend switching to The Fulton Bolt-Thru Swivel Marine Jack with Dual Wheels - Sidewind - 12 inch Lift - 1,500 pounds # FXPD15L. This jack has a lift capacity of 1,500 pounds, and has a heavy-gauge steel construction. It has a 600-hour salt spray rating, and has a 12 inch lift. I attached a review video link below.

  • Recommended Replacement for a Shelby Trailer Jack Model 5756
    In order to replace the Shelby Trailer Jack Model 5756 you have on your trailer now, I recommend taking a look at the Round Swivel Marine Jack w/ Wheel part # MJ-1206B. This jack bolts onto a trailer frame up to 4" tall and will not require any welding. It has a zinc plating for corrosion resistance which is ideal for boat trailers and it has a caster wheel for easy maneuvering. There is an integrated swivel feature which operates with a pull pin and the jack can withstand up to 1,000 lbs...

  • Overall Retracted Length of Round Swivel Marine Jack MJ-1206B
    I went to our warehouse and measured the Round Swivel Marine Jack # MJ-1206B for the dimension you asked for. When fully retracted, from the bottom of the wheel to the top of the jack tube the overall length of the jack is 23-inches. From the bottom of the wheel to the center of the mounting bracket the dimension is 13-inches. I prepared a photo for you showing these dimensions.

  • Recommended Trailer Jack With Wheel for 2.5 x 2 Inch Trailer Tongue
    For your 2.5 inch wide and 2 inch high trailer tongue, the Round Swivel Marine Jack w/ Wheel - Bolt On - Zinc - Sidewind - 11" Travel - 1,500 lbs # MJ-1500B is my recommendation. It will work very well with the trailer tongue you have and will give you 11 inches of travel from the 13 inch retracted height. I've attached a photo to assist as well as a couple videos.

  • Are Replacement Parts Available for Shelby 5854A Trailer Jack
    Shelby has been out of business for a number of years now and so there unfortunately are no replacement parts readily available. You might be able to find something where old parts are regularly sold, but you'll probably have to do a lot of digging and it would be much easier to just upgrade your trailer jack now so that when something needs to be replaced in the future it's a lot easier. For a replacement I recommend checking out the Round Swivel Marine Jack w/ Wheel # MJ-1206B rated...

  • Recommended Jack For Log Splitter That Mounts To 2-1/2" Swivel Base With Snap Ring
    I have another option for you, but the Round Swivel Marine Jack w/ Wheel - Bolt On - Zinc - Sidewind - 10" Travel - 1,000 lbs # MJ-1206B you were looking at for your Log Splitter does not have a 2.5" swivel base and snap ring, and instead uses a bolt to attach it to the mount. To replace your current jack you will want to go with the Fulton Round, Snap-Ring Swivel Marine Jack - Bolt On - Sidewind - 10" Lift - 1,200 lbs # FTJ12000101 instead. This jack has a 200lb higher load rating than...

  • Trailer Jack Recommendation or Trailer with Angle-Iron Frame
    You would have to box the frame to install the trailer jack part # MJ-1206B as it cannot attach directly to an angle-iron frame. The Fulton # FTJ120W0301 which is a weld-on application would be an excellent choice as well. You would just weld it directly to the frame.

  • How Does etrailer Ram Jack MJ-1206B get Lubricated
    There is a hole under where the handle inserts into the etrailer jack part # MJ-1206B which is where you'd spray lithium grease into to lubricate the screw and assembly.

  • Replacement A-Frame Jack Wheel Needed for a 2008 Forst River Flagstaff Pop Up
    Since the wheel on your jack is removable you can definitely replace it! Just let me know what the diameter of the inner tube of your jack is along with the pin hole diameter and I can make a recommendation. For example, the removable wheel # DL22539 has a weight rating of 1,250 lbs, fits jacks that have an inner tube diameter of 2" and uses a pin that is 1/4" in diameter. If you would rather just add a swivel jack then that is a viable option as well. Simply make sure you have enough...

  • Does The Location Of The Swivel Jack On The Tongue Or Within The V Matter?
    The Round Swivel Marine Jack w/ Wheel - Bolt On - Zinc - Sidewind - 10" Travel - 1,000 lbs # MJ-1206B can absolutely be installed on the tongue part of the trailer. The video you are referring to I have attached and it wasn't added to the tongue because of the other components that are already present there. If you look at our customer photos you can see this jack can be used on the tongue without issue.

  • Trailer Jack Cap that Fits Haul-Master 1000

  • Trailer Jack for Trailer With Non-Traditional Trailer Tongue
    The only option to add a jack to your trailer with that tongue would be to drill in and attach it to the front of the trailer itself. You could use the Round Swivel Marine Jack w/ Wheel # MJ-1206B and bolt it straight onto the frame instead of using the brackets to go around the frame. What I would really recommend is cutting off that trailer tongue and adding a new one. This would allow you to install a trailer jack on the tongue itself. Also, I'm not sure how that trailer is towed, but...

  • Best Boat Trailer For 12'6" Inflatable Boat That Will Also Work For 14' Aluminum Boat
    The CE Smith Multi Sport Plus Boat and Kayak Trailer w/ Bunks # CE48870 is a great option for both boats. It is capable of transporting boats up to 14' long that weigh up to 800lbs. The winch stand can be moved front to back to accommodate for different length boats to keep the weight positioned in the correct place for the trailer. The CE Smith Post-Style Guide-Ons with LED Lights # CE27740 will help you to guide the boat onto the trailer when loading but are also great for maneuvering...

  • What Size Inner Tube Is On the etrailer Boat Trailer Jack
    Kelly, the etrailer Boat Trailer Jack # MJ-1200B you're referring to has an outer tube diameter of 2" and an inner tube diameter of 1 3/4". The wheel that comes with this jack is a JWK-6P # JWK-6P, and the bolt measures 3", has a 7/16" diameter thread, and the main shaft measures 1/2".
