- TJD-12000SP-F2

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 etrailer.com 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.

Review from a similar Ram Square Sidewind in Trailer Jack

Was having issues with the trailer lifting the backend of my truck when I loaded tractors. When I would drive the tractor on the back of the trailer would go down from the weight on the rear which caused the front of the trailer to lift the backend of my truck. So, I bought a couple of the Square, Pipe Mount, Swivel Jacks with Footplates and a Drop Leg. They are Topwind, 7K, Jacks. I had them welded on. This should stop the issue I'm having. I know the 7K was a little over kill but the price was great.

The Jacks are working great. Definitely fixed my problem and make easy for me to load heavy equipment now. Thanks again for a great product!!!

Review from a similar Ram Square Sidewind in Trailer Jack

I like the direct weld jacks. But I wish at least the outside tube was thicker with a little moe clearance with the inner tube. I put them on a 2020 Griffon 14’x7 ton dump trailer. I could not weld them directly to the trailer frame because I would not be able to crank the handles. I had to weld 1/2” x6” plates to the jacks to off set them farther from the fenders. I might use a little to much heat. Before I welded them the crank handles were very free. After welding they bind a little bit. But they still work great.

Review from a similar Ram Square Sidewind in Trailer Jack

This is my fourth project using this jack over the past ten years. The retractable post and long reach provide lots of ground clearance. The weld-on square tube mount design makes it simple to configure to any orientation and height, and is more durable than any "swing-away" style jack can ever be. In ten years, I have "driven off with the plow down" several times and it does not bend. This jack is well worth the money and etrailer is a very reliable vendor. I will buy this again.

Review from a similar Ram Square Sidewind in Trailer Jack

Great quality jack. I had never owned a heavy trailer previously. Grew up with 3,000 pounders and finally purchased 18 ft enclosed. It came with an a-frame 5,000 pound jack which was toast after a couple of uses the way I organized the trailer. Purchased a replacement which lasted 2-4 weeks before it was no longer working. Purchased a 2nd replacement 5,000 pound a-frame jack which lasted a week. For those who dont know....don't go through the headache and money. Get yourself a square jack. Get this one or something else heavy duty if its going to be a heavy load. Once you have 1 of these you'll never go back! No other option couldn't be more satisfied.

  • 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.

  • 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...

  • 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.

  • 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...

  • 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-...

  • 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.

  • 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...

  • 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.

  • 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...

  • 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.

  • Will the Ram Replacement Handle Shaft Work Work On a Ram 12K Square Tube Jack

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.
