Very happy with the jack I purchased and will be buying from you again when needed


Works great, etrailer always takes care of us. Great folks to work with.


Very well made and functions as it should.I welded it in place on the traier, it makes unhooking while loaded a breeze, has no problem lifting a loaded trailer.


Did exactly what I wanted.


works great, was a great price also

Still working great after a year!

Quick delivery and very easy to order.

Brad - 01/22/2022


If you’re needing a new jack. Look no further, cause this is the one for you!! It will take care of all your lifting!! LOL!!




Came on time and in good condition. happy so far, I have yet to use the product but. I can tell the landing gear is pretty stout and well made.


Thank you Thank you very much if they would let me give you 6 stars i would.
I had a jack go bad over the race weekend trailer was stuck on my truck.So i called
my trailer MFG on Monday and they put me off for 2 days with no help.
So i decided to pull the front metal plate off found out that is was a ram jack so that night i found you thru ram jacks sent me to so i ordered it.
You packed it and shipped at 4am your time the next morning i paid for 3 to 5 day shipping and i met the UPS guy on Thursday morning you got it here a day sooner.
6 hours later the trailer is off my truck after cutting and cutting grinding and welding trailer MFGs weld these on before they put the walls in so welds in blind places.
The product is a very good but your pricing rocks and your service is the very best
great job you have all my business for trailer needs.


Only complaint is the picture shows it with a crank but it didn’t come with one


Works great!


My son and I built a ten bale hay carrier. We needed a heavy jack for the bale hauler. It works great and so does our bale carrier.




Very pleased. I like how yall kept me up to date with it and seething was great. We will be ordering from yall again.

We appreciate the timely service and delivery of the equipment ordered. But components of the total package that are also needed, are still pending so this
hopefully will be resolved soon.

Still going strong.

  • Can the Square 2-Speed Jack w/ Crank Be Used In Tandem
    Yes, in order to use the Square 2-Speed Jack w/ Crank part # TJD2SP-12000SP-F in tandem you would need to obtain the correct follow leg which is the Square Direct Weld Jack part # TJD-12000SP-F2. The handle for this follow leg can be discarded as you would want to use the handle on the lead leg with the two speed operation. There would then need to be a cross shaft made to connect the two jacks but we do not offer this. That said, a trip to your local hardware store would allow you to get...

  • Replacement Inner Tube and Drop Leg for 12K Pacific Rim Trailer Jack
    For your 12K Pacific Rim square jack the correct inner tube with drop leg is the part # TJD-12000SP-FIP. This is a direct replacement for the Ram/Pacific Rim 12K trailer jacks like # TJD-12000SP-F2, which are often used as OEM/factory units on newly built trailers. I have included a short video review on this product as well so you can verify it looks like what you currently have.

  • 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.

  • Replacement 4 x 4-Inch Cap for Jack Tube
    We do offer both round and square replacement caps for many brands of jacks. All are shown on the linked page. Part # TJD-12000-CP fits a 4 x 4-inch outer jack tube like on # TJD-12000SP-F2.

  • Will the Ram Replacement Handle Shaft Work Work On a Ram 12K Square Tube Jack
    The Replacement Handle Shaft for etrailer and Ram Square, Direct Weld Jacks part # TJD-12000-SHABUS is designed specifically for the Ram Direct Weld Trailer Jacks TJD-12000 like part # TJD-12000SP-F2 for example. The Ram Direct Weld Trailer Jacks TJD-12000 have a 10,000 lb lift capacity and a 12,000 support capacity. I think this is what you have but all you need to do is confirm the model number starts with TJD-12000 (see label) or measure the one you have now.

  • 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.

  • Threaded Rod, Gears, and Pins for Ram Square Sidewind Jack
    For your Ram 10,000 lb jack, it sounds like you will need to rebuild it as the amount of force used most likely damaged the gears and the threaded rod. I recommend the Replacement Rod and Nut for etrailer and Ram Square, Direct Weld Jacks - 12K # TJD-12000-RODNUT along with the Replacement Sidewind Gear Kit for etrailer and Ram Square, Direct Weld Jacks - 10,000 lbs # TJD-12000-GR designed for use with TJD-12000 Series jacks. There is most likely not a clean and easy way to remove the...

  • My 10,000 LB Jack On My PJ Trailer Won't Work and Is Weld Mounted
    When these types of jacks fail, they often just need to be replaced. You may be able to find a part if you were able to dismantle it and figure out the issue, but that part may not even be available as a replacement. Since your existing jack isn't working for you, I recommend replacing the jack. This does entail having the old jack cut off and welding a new jack to your trailer. The trailer jack I'd suggest would meet your needs is the Square Direct Weld Jack - Drop Leg w/ Spring Return...

  • Does etrailer TJD-12000SP-F2 Ram Jack Include Hand Crank
    The etrailer brand # TJD-12000SP-F2 Ram Jack includes everything shown in the product photos, including the crank handle. We take all our own product photos here, and unless the product description states 'Typical Photo', everything shown in any of our product photos is included with that part's purchase.

  • Best Single Speed Jack To Pair With 2 Speed Square Tube Jack
    These are both great questions! Jacks with 2 speeds have the gears changed by either moving the handle to a different spot on the jack, or having the handle pushed in or pulled out to change the gear that is engaged- with this specific jack, you'll push the handle in or pull it out to change speeds. With a dual speed jack, the input speed is changed but the output speed does not change, so you would be able to use a 2 speed jack as the lead leg and a single speed jack as the follow- so...

  • 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...

  • Determining The Correct Replacement Drop Leg Return Spring For 10,000lb Side Wind Trailer Jack
    I would be happy to help. The correct replacement return spring for the jack feet on your 10,000lb side wind jack will be dependent on which brand it is. For example if you have an etrailer or Ram branded jack such as the # TJD-12000SP-F2 then you would want the Replacement Return Spring # TJD-12000-RSP. However Bulldog jacks do not have a replacement return spring, so if it goes bad the jack needs to be replaced. I included videos of the products mentioned for you to take a look at.

  • Can Pin for Drop Leg be Moved on Pro Series Square 10,000 Pound Jack # PS1401010376
    The pin location cannot be changed but we do have Pro Series jack # PS1400950376 or # PS1400980376 which do have the pins on the front (or back depending on how you have the jack positioned). Another option is # TJD-12000SP-F2 or # TJD2SP-12000SP-F.

  • Recommended Weld-On Square Jack with Removable Handle for 4 Corners of Trailer
    The Pro Series Square Jack with Footplate - Drop Leg - Sidewind - 15" Lift - 5,000 lbs # PS1401600383 cannot have the handle removed and reinstalled easily. It would require opening up the jack each time. I recommend using the Square Direct Weld Jack - Drop Leg w/ Spring Return - Sidewind - 12-3/8" Travel - 10K # TJD-12000SP-F2 for your application.

  • How To Use Two Square Direct Weld Jacks Together
    The Square Direct Weld Jack part # TJD-12000SP-F2 can be used in tandem. The only thing you would need to do so would be a cross shaft which would be some sort of bar that attaches the two output shafts to one another. This is assuming you want both jacks to turn at the same time and not have independent operation with two handles. In regards to the cross shaft, you should be able to cut the Cross Shaft Extension Tube part # BDCS730300 to make it work.

  • Availability of 2 Speed Landing Gear Style Jack that Can Have Motor Added to It
    Since we don't have a powered drive kit for the Ram jack # TJD-12000SP-F2 your best option would be to use the powered drive kit part # BD1824180100 with the Bulldog 2 speed jack part # BD183416 and you'd be set.

This would only work on scissor jacks like the Leveling Scissor Jack Set # JSC-24 which can utilize the adapter # UF48-979005.
