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! 722582

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. 712037

  • 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...

  • 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...

  • 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.

  • 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...

  • 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.

  • Repair Kit for Ram Series 12000 Trailer Jack
    To repair a Ram Series 12000 jack, like # TJD-12000SP-R2, we have the Gear Kit # TJD-12000-GR or the Replacement Rod and Nut # TJD-12000-RODNUT. Or you could need both. I just depends on what the problem is exactly.

  • 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.

  • 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.
