• Are RAM Jacks and etrailer Jacks the Same
  Kelly, the RAM jack MJ-1200B is the same thing as the etrailer # MJ-1200B. The discrepancies in the outer and inner tube measurements (3/8") are what we measured, versus what the original manufacturer measured. Sometimes the manufacturer measures one thing, but when we get our hands on it and re-measure it for our site we get a different measurement, which I believe is what you're seeing here.

• How Do Bolt-On Round Swivel Marine Jacks Mount to Trailer
  The Mounting Kit # MJ-1000B-MK is a replacement part for the Round Swivel Marine Jacks # MJ-1200B and # MJ-1500B which actually mounts to the side of the frame of your trailer instead of in the hole location in your A-Frame coupler area. As long as your trailer frame is 2" to 4" tall this bracket system will work for you. If you're needing a different style that mounts in an A-Frame I recommend either the manual # TJA-5000S-B or electric # EJ-3527-BBX. These have a 2-1/4" outer diameter...

• 1995 Freedom Wheels Cobalt 220 Runabout Replacement Trailer Jack Recommendation
  Thank you for the photos! While it doesn't look like we have anything that mounts directly to your current mounting bracket, we do have some bolt-on replacement swivel jacks that will work perfectly for your application. For a single wheel replacement I recommend the Round Swivel Marine Jack w/ Wheel # MJ-1200B with 11" of travel and a 1,200 lb weight capacity, or for a dual wheel jack (for easy maneuverability) we have the Round Swivel Marine Jack w/ Dual Wheel # MJ-1500B-DWL which has...

• Is There a Replacement for a Shelby Jack 5856A That Uses Existing Bracket
  I do have an option for you but the Shelby trailer jack mounting bracket that you have welded to your frame won't be able to be reused with any newer jack. The Shelby trailer jacks did use similar designs in regards to mounting like the bolt-through and snap ring that some current jacks have but they are simply not cross-compatible. The bolt-through option for example from Shelby has a flat plate whereas the current models have a recessed portion. Therefore, the best option for you would...

• Replacement Jack Options For a Shelby 4587 Trailer Jack On a Boat Trailer
  I have a couple options for you to consider as no one makes a jack that will bolt on in place with your Shelby 4587 jack bracket you have welded to your frame. First the Round Swivel Marine Jack w/ Wheel # MJ-1200B is the closest we have to the design of your jack. This will bolt to your trailer frame either just behind your current welded jack bracket or you can have the bracket cut off and install the jack in the same place. The Xtreme Off-Road Swing-Up Trailer Jack w/ Dual Wheels...

• Replacement for Shelby 5764A Trailer Jack on 2000 Four Winns Horizon 180
  Swapping the mounting hardware on a jack can be done, but it will depend on the specific mounting hardware of the jacks. Shelby jacks and parts are becoming more difficult to locate, so I would recommend replacing your Shelby hardware with something more easily replaceable in the future like the etrailer Marine Jack # MJ-1200B, which has a 1200 lb capacity and 11" lift. If you want to try to match the existing Shelby mounting plate, we do have one jack that may work. The Fulton Bolt-Thru...

• Looking For Trailer Jack With 1-3/4" Tube Diameter
  Hello Kirsten, thanks for reaching out. Unfortunately, we do not offer a trailer jack with a 1-3/4" outer tube diameter. There used to be a jack from Bulldog that had a 1-3/4" tube diameter, but it has been unavailable for quite some time. Most of the jacks we offer have a 2" outer tube diameter like the etrailer Boat Trailer Jack # MJ-1200B. The inner tube has a 1-3/4" diameter, but the outer tube is 2".

• Replacement for Shelby Trailer Jack on Four Winns Boat Trailer
  I do have an option for you but Shelby boat trailer jacks are discontinued and we don't offer any direct bolt-on replacements for them. That said, you can easily remove the old flange by cutting or simply place the new jack beside it and leave the old flange in place. I recommend the Round Swivel Marine Jack w/ Wheel part # MJ-1200B which offers a bolt-on install with wheel for easier maneuvering.

• Looking For A 1 5/8 Caster Wheel For My Pop Up Camper
  Hey Jordan, The closest option that we have to the 1-5/8" you are looking for is going to be the Ultra Fab # UF49-954035, which is going to fit a 1-3/4" diameter inner tube. Its going to be an 1/8" larger than what you need. 1-5/8" is not a standard size which is why it is difficult to find a replacement. You will either have to find a wedge or something like a small adapter tube for this to work for yours. Typically in these situations I recommend going with a new jack as a whole that...

• Recommended Trailer Jack with Lower Retracted Height for Landscaping Trailer
  I looked through our selection trying to find a similar jack to the MaxxTow MT70149 with a retracted height less than 14-3/4 inches and found a couple of good options for you. You didn't say exactly what height you need, however part # MJ-1200B has a retracted height of 12-1/2 inches. The weight capacity is slightly less, at 1,200 pounds but that's probably still plenty for your trailer. It also offers 11 inches of travel which is a 1/2 inch less than the MaxxTow. A second option is...

• How To Add Tongue Weight To a Small Motorcycle Trailer
  The issue you are having with excess sway is pretty common on light trailers. The sway issue might then be minimized when you have your motorcycle attached but odds are you are still going to have sway issues. The overall weight of the trailer is a concern but more importantly is the tongue weight. The best option you have to decrease trailer sway with your trailer would be to add as much weight as you can to the tongue. The best way to add the most amount of weight would be to make some...

• How To Replace Welded-On Trailer Tongue Jack for Boat Trailer
  In order to remove a welded-on trailer tongue jack you will need to cut off the old welds to release the mounting bracket. This can be done using an angle grinder. The jack can then be replaced with another welded-on option such as the Fulton Marine Jack part # FXP100W0301. If you don't have an angle grinder or the skills to use one you can always leave the mounting bracket attached and just install a bolt-on jack in front or behind it, I recommend the Round Swivel Marine Jack part # MJ-1200B.

• Replacement Jack for 2009 Ranger Boat Trailer
  Trailer makers don't maintain detailed specs on items like the jacks they supply on their new trailers but we do offer many types and capacities so we'll have one that will work for you. It is best to select a jack with more capacity than you actually need; the same is true for hitches and winches. Such items, when operated below their maximum capacity, typically last longer than ones used near their limits. I linked our main page for side-frame-mount jacks. You can click on your required...

• Replacement Side-Frame-Mount Swivel Jack for 1992 StarCraft A-Frame Pop-Up Camper Trailer
  We can help you with a new jack for your 1992 StarCraft pop-up camper. Usually an A-frame trailer like this will use a jack that mounts in the standard receptacle behind the coupler. Jacks for this kind of A-frame installation are linked for you. We have manual and electric types, top-wind and side-wind types, bolt-on and weld-on models and you can choose either a wheel or footplate. But sometimes a jack in this location can pose clearance issues with other trailer-mounted items or with...

• What Replacement Parts Are Available for an etrailer MJ-1200B or Fulton Swivel Marine Jack

• Replacement Swivel Jack with Lowest Possible Retracted Height for Use on Small Utility Trailer
  I was able to find a swivel jack option for you that has a retracted height of 11 inches from the bottom of the wheel to the center of the mounting bracket, but none of the trailer jacks with a caster that we offer have a retracted height of 10 inches or less. The jack that may work best for you is the Fulton F2 Trailer Jack, like # F1413040134. This jack has an adjustable mounting bracket with the lowest retracted height being 11 inches. The lift height of the jack is 10 inches, and...

  We do sell replacement jack parts including the main screw like the one shown in your photo. Examples of these replacement jack screws are # TJD-12000-RODNUT, # BD500250 and # BD500217 which are shown on the linked page. Unless you can positively identify the model of Fulton jack you have I strongly recommend replacing the whole jack instead of trying to rebuild the old one. You may even save money by getting a new jack; you'll also get a new warranty and have the confidence of knowing...

• Is 1,500 lb Trailer Jack Enough for 21 ft Boat Trailer
  Trailer jacks are rated for the amount of tongue weight that the trailer has. Typically trailer tongue weight is around 10 percent of total trailer weight. So for a 1,500 lb jack to be at capacity the trailer would most likely weigh near 15,000 lbs. So a 21 ft boat trailer would have no problem with a 1,500 lb jack capacity. Our most popular swivel jack for a boat trailer is the part # MJ-1200B which has a 1,200 lb capacity and would work well.

• 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....

• Grease Port Location For Ram Jack MJ-1200B
  Actually the hole that you see under the handle on the Ram Jack part # MJ-1200B is the port for lubricating the jack. Sometimes there is a zerk fitting there but for your jack it's just an opening. You would want to spray a lithium grease into that hole to keep the parts lubricated. Or you can remove the cap and spray down into the main tube of the jack that way as well.
