How to Determine the Support Capacity You Need in Your Landing Gear

If you will be using this landing gear to lift and lower your trailer onto a hitch ball or kingpin, then you should choose the jack you need based on its lift capacity. But, if you are just using it to stabilize or support a parked trailer, then you should focus on the jack's support capacity.


Heavy-duty jacks like this one stabilize about 25% of your trailer's total weight when it's loaded up. For example, a 50,000-lb trailer has a pin weight of about 12,500 lbs. For these legs to work, you'd need a set of landing gear with a combined lift capacity of no less than 12,500 lbs. If you only have one jack that can get the job done, that's great! In fact, this should work more efficiently, allowing you to spend less time cranking.


Note: Do not use landing gear to lift your trailer during tire changes or service work, because doing so will exceed the capacity of the landing gear.

by:

cardboard box was totally trashed but Everything made it. Look forward to getting it welded to the dump trailer and an easier lift. Thank you !!



by:

Shipping box had some but the jack was fine. Heavy item and not very much packing to prevent it from rolling inside the box.



by:

Product was what to be expected no issues there. Etrailer shipped fast and we never have an issue with them. Buy from Etrailer you won't regret.



by:

Very well built. Paint isn't the kind that will last very long but I expected that. The rate the leg drops compared to the number of cranks is a bit slow but that makes it a lot easier to lift my heavy trailer. Make sure you grease it before using. Didn't have much grease in it.

I hope that you will get a lot of use out of the jack. As for the paint we recommend keeping a can of Rustoleum on hand to touch up the jack from time to time.



by:

Great job! Always delivers on time. Used the jacks on my service body that I mounted a crane on for outriggers.



by:

Great product I have been swapping out to these jacks as I upgrade my trailers



by:

the Jack w/crank was great, easy to ins tall

I ordered this jack on Friday late evening over the Easter holiday and received it Monday. Fast shipping
I’m going to have it installed on my PJ dump trailer.

After a year of use and abuse it’s working great and no problems.



by:

i purchased and installed this jack about a year ago on a home-made trailer and it has been great. i used it as a center support jack and bought a piece of pipe to extend the handle to the outside of the trailer and i have had 0 issues. it was easy to install and has been working flawlessly. Thanks for the quality product etrailer!



by:

I purchased this jack a year ago. Works great. etrailer.com our choice for all our trailers maintenance and repairs parts



by:

Ram makes great product customers very happy



by:

This jack is a replacement for a factory installed jack of a much lower rating that has failed. I can buy a lot more jack from etrailer for the same or less than the local dealers wanted for a direct replacement. I placed my order and was happy to see it was shipped and arrived to me in 2 days. It was packaged well, almost to well. Do you buy those staples to close boxes by the ton? I feel a lot better unhooking the trailer with a load now.



by:

Delivery was quick and was what I wante d.



by:

Very solid. I am using two of these for a water trailer that is 10,000 lbs full. They have never been anything but smooth and the spring loaded foot saves LOTS of cranking time.



by:

I busted my 20 year old jack coming out of camp, got this replacement quickly and it works great !!!

Was having trouble locating parts for a ram 12000 Jack these guys show parts on their sight but when I called parts weren't in stock but they had a replacement unit that I could use for parts .shipped out that day , quick service.will use again.



by:

Easy to navigate their web site to order from. Lots of products also. I purchased my jack stand because of the price and free shipping option. When I received my jack it was excellent quality and as I said, you can't beat the price. I think I received it within 5 days including the weekend. At any rate I will buy again and I couldn't be happier. Thank you.



by:

This is at least the seventh time I have ordered from etrailer.com and everytime I have had great service and an excellent product to install on my customers projects. Thanks again, will be shopping with you again soon.



by:

etrailer was very helpful in informing me that the jacks that I originally ordered were out of stock and had a long lead time and we very helpful to identify a replacement jack that was in stock. The jacks were in my possession in 4 days after the order was placed, good job!.



by:

Jack was delivered in excellent shape in a box of the Appropriate size. The picture and description accurately depicts the jack delivered. It will be used on a old trailer that in the past the tongue had been held up by a piece of wood. Thanks etrailer.



by:

Jack work perfectly after mounting, and was priced competitively.

I buy products from etrailer every week almost to replenish my supply for all the trucks and trailers we keep up. I have found they ship fast and efficiently and they sell good products. I have been very satisfied to find them as a vendor and will continue to buy the great products they sell.

  • Comparing the Square Direct Weld Jack TJD-12000SP-F2 and TJD-12000SP-R2
    The main difference between the Square Direct Weld Jack part # TJD-12000SP-F2 and part # TJD-12000SP-R2 is the location of the plunger for the drop leg. The former has the plunger on the side of the crank handle and the latter has the plunger adjacent to the crank handle. Furthermore, the former has a 1-1/4" diameter jack screw and the latter a 1" diameter jack screw. Aside from the location of the plunger and size of jack screw, the jacks are essentially the same.

  • How to Safely Use the Square Direct Weld Jack TJD-12000SP-R2
    If you aren't familiar with a jack like Square Direct Weld Jack # TJD-12000SP-R2 it can have a little bit of a learning curve. Here is how it works: As you probably know the jack leg retracts quickly. First make sure the jack is not supporting a load. If the drop leg is extended the operator should place a foot on the foot plate to control the return of the drop leg. To lower the drop leg turn the pin to the disengaged position. The bracket around the pin is shaped so that when the pin...

  • Can the Drop Leg Plunger Pin Be Relocated on the Square 10K Direct Weld Jack
    I do have an option for you but the drop leg plunger pin cannot be relocated, you will instead need to purchase a different jack with plunger pin in the correct location for your needs. The Square 10K Direct Weld Jack for example is offered with two different plunger pin locations, part # TJD-12000SP-R2 for side or part # TJD-12000SP-F2 for front. In other words, you'd need to remove the existing jack and weld a new one into place with the correct plunger pin orientation.

  • Comparing the Pro Series Jack Part # PS1400950376 and the RAM Jack Part # TJD-12000SP-R2
    Yes, both the Pro Series Square Jack part # PS1400950376 and the Square Direct Weld Jack part # TJD-12000SP-R2 are made of steel. The Pro Series jack has a one year warranty and the RAM jack also has a one year warranty. They both have a 10,000 lb lift and 12,000 lb support capacity although the RAM jack does offer a bit more lift at 13-1/2" compared to the 12-1/2" of the Pro Series jack. Essentially, the jacks are pretty much the same for the exception of brand. I have attached a review...

  • Dimensions for Replacement Square, Direct Weld Jack Inner Tube with Spring-Return Drop Leg
    The drop leg portion of the Replacement Square, Direct Weld Jack Inner Tube with Spring-Return Drop Leg # TJD-12000SP-FIP measured about 3" square and is about 19" tall. Please note that this part is a direct replacement for jacks # TJD-12000SP-F2, # TJD-12000SP-R2, or # TJD-12000SP-R2NH so if you don't have one of these you will likely need to do some modification for this to fit.

  • Is There a Drill Adapter Which Is Compatible With 1 Shaft On a Square Trailer Jack?
    While there is not a drill adapter for the Handle Shaft # TJD-12000-SHABUS on a Square Jack # TJD-12000SP-R2 I do have some ideas for you. First you can have the handle shaft machined down to accept the Ultra-Fab Speed Socket # UF48-979005. This includes a 12 point 3/4" socket which will also fit a standard 6 point head. Another option would be to cut the end off a Crank Handle # TJD-12000-HD and weld on a drill end. This means you do not have to modify the shaft on the jack.

  • Gear Kits for Single Speed Ram or etrailer Jack
    It is not possible for me to tell you with any degree of certainty that you can retrofit the Replacement Gearbox for etrailer and Ram 2-Speed Square Jacks # TJD2SP-12900-GBX for use with a single speed Ram jack though there are replacement gears available. If you have the TJD-12000 Series jacks such as # TJD-12000SP-R2 there is the Replacement Sidewind Gear Kit # TJD-12000-GR as well as Replacement Rod and Nut for etrailer and Ram Square, Direct Weld Jacks # TJD-12000-RODNUT which you...

  • How to Replace Interior Ram Jack Rod and Nut # TJD-12000-RODNUT on 12000 Series Jacks
    Good news! I was able to get a exploded diagram as well as a set of instructions on how to replace the rod and gears # TJD-12000-RODNUT in the # 12000 Series Ram Jacks made after 2012. I have attached them to this page for your convenience. Basically, you will not need to remove or cut the steel plate inside the top of the jack to do this. You will want to remove the cap, then the roll pin that holds the cross shaft into the leg, this will free up the smaller gear that will be removed...

  • Can The Square Direct Weld Jack # TJD-12000SP-R2 Be Operated With Impact Wrench?
    The Square Direct Weld Jack # TJD-12000SP-R2 is only intended to be operated with the included handle. Using an impact would cause damage to the gears inside the jack as well as the vertical screw rod.

  • Replacement Nut for Ram Series 12000 Jack
    The Replacement Rod, Nut, and Grease Trap # TJD-12000-RODNUT is a fit for the 12000 series of Ram or etrailer jacks such as # TJD-12000SP-R2. It is specifically designed for square, direct-weld TJD-12000 Series jacks; the lift nut will fit 3-1/2" x 3-1/2" square jack inner tubes. If this matches the description of your jack it will work for you.

  • Will the Bulldog Powered-Drive Kit Work On RAM 12K Jacks
    Yes, we have heard back from our customers that the Bulldog Powered-Drive Kit for Single-Speed Jacks part # BD1824200100 will also work on 12,000 lb RAM jacks like the Square Direct Weld Jack part # TJD-12000SP-R2. I would have to agree as well because they both use a 1" diameter drive shaft. I have attached the customer review confirming fit for you.

  • Is There a Replacement Screw and Nut for TJD-7000S Ram Sidewinder Jack
    The Square Direct Weld Jack w/ Footplate - Drop Leg - Sidewind - 28-7/8" Lift - 7,000 lbs # TJD-7000S does not have the replacement screw rod and nut assembly available as a replacement part. You will need to replace the entire jack. I recommend the Square Direct Weld Jack w/ Crank - Drop Leg w/ Spring Return - Sidewind - 25-3/4" Lift - 10K # TJD-12000SP-R2 which will have replacement parts should you ever need them.

  • Can Internal Rod Be Replaced for Heavy Duty Bulldog Jack
    Hey Tim, thanks for reaching out! It doesn't look like Bulldog has replacement rods for their HD jacks so I recommend replacing it with a 10K etrailer jack # TJD-12000SP-R2 or # TJD-12000SP-F2 depending on which way you need the spring handle to face for the drop leg. If the rod ever goes out on this then you just need the Replacement Rod and Nut # TJD-12000-RODNUT to get the trailer jack back up and running.

  • Are There Replacement Jack Parts for Jack on OTM Gooseneck Trailer
    I do have an option for you but you'll have to replace the jack on the trailer to get it back up and operational. It's simply not feasible to find replacement parts for a jack this old. It's likely the company who made the jack is no longer in business or no longer offers replacement parts for this due to the age. I recommend the Square Direct Weld Jack part # TJD-12000SP-F2 which has a forward facing return spring or part # TJD-12000SP-R2 which has a side facing return spring. These jacks...
