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!.


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


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

leo r - 07/24/2022


Great price and the best quality THANKS i will be ordering another one for my other 2 trailers


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


Jacks were good quality and came with the crank handle. Would buy again.


Works great on my Hillsboro stock trail er!


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.

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!


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.


Well made for the price. etrailer always has great service. A++


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.


This is at least the seventh time I have ordered from 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.


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.


As described but even more impressive the shipping and communication


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.


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.


Product looks great package was a little rough when I got it bolt was missing for jack handle nut was there


Using to repair a damaged jack on trailer. Jack is a little bit looser than original but I think it will work out great.


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.


Jack looks exactly like advertised. Glad I got spring return. Old one didn't have it. Quick shipping.


I put it onto a large dump trailer, clearly much heavier then the original. I am very happy with it it has out preformed my expectations


Use to upgrade from a 7000lb jack. Its heavy duty and just what I needed. cranks easy and nice. hope to never replace it again.


Good performance after a year. The spring return is good and the operation of the jack performs very well.


Had wonderful service on the phone with Paula. Placed the order for parts and a new jack Monday morning and got delivered Wednesday morning!

  • 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.

  • 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...

  • 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...

  • Is Specific Amount of Ground Clearance Required when Installing Direct Weld Jack # TJD-12000SP-R2NH
    There isn't a specific amount of ground clearance required when installing a jack such as Square Direct Weld Jack # TJD-12000SP-R2NH. You would mount it however it is needed for your trailer. The overall height of the jack when fully retracted is 28 inches. When fully extended and the drop leg all the way out as far as it can go the height is 40-1/4 inches. Based on this information you will be able to figure out the position that will work best on your trailer.

  • 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. I've attached a video to assist.

    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.
