Features to know about

Built for Heavy Loads: 10,000 lb Lift Capacity With Smooth, Easy Cranking

When you’re hauling serious weight, you need a jack that won’t flinch under pressure. This square direct-weld jack handles a 10,000 lb lift and 12,000 lb support capacity with a durable 1" jack screw that turns smoothly even under load. Twin thrust bearings make raising and lowering steady and controlled instead of a chore. Weld it to your frame once and you’ve got a setup that stays solid job after job.

Faster Height Adjustments: Spring-Return Drop Leg Saves Time

Instead of spinning the handle forever to reach the ground, you just pull the side-mounted plunger pin and let the spring-return drop leg do the work. The leg adds 13-1/2" for a total adjustment of 25-3/4", so you can fine-tune height fast and get moving again. When it’s time to retract, the spring pulls the leg back automatically—no need to lift it by hand.

Reliable in the Field: Heavy-Duty Steel With Wide 8-1/4" x 8" Footplate

Soft ground, gravel, and uneven pads are no problem for the solid rectangular footplate that keeps this jack steady and prevents sinking. Both the outer 4" tube and 3-1/2" inner tube are built from heavy-gauge steel with a black painted finish for long-term durability. The thick weld areas and sturdy construction hold up to regular work use without flex or wobble.

Simple Upkeep: Built-In Grease Zerk for Effortless Maintenance

Keeping your jack smooth is as easy as a quick shot of grease. The integrated grease zerk fitting lets you service the internal screw without teardown or disassembly, keeping corrosion and wear at bay. That means less downtime and smoother cranking every time you hook up.

Straightforward Setup: Weld-On Fit With Easy Replacement Handle Option

Mounting is direct and secure thanks to the weld-on design. The plunger pin sits to the side for easy access even when space is tight. The matching sidewind handle (part # TJD-12000-HD) installs with the included hardware when you’re ready to complete the setup. With replacement parts available for the screw, gears, and return spring, this jack is made to stay serviceable for years.

Still working great no problems with any of the jacks



by:

Its a good jack. Unfortunately the only reason its not getting 5 stars is because the spring broke within the first 20 uses. But it still works fine



by:

The jacks seems to be holding up, i use them as downriggers for my service truck crane. Only gave 3 stars because one of the feet on the jacks came bent and etrailer offered to send me a new jack at over $[XX] shipping or some casy back. So i took the $[XX] cash back for my 300$ jack.



by:

This was a replacement for a jack that had failed. Dimensionally it was as advertised. I received the jack ahead of schedule, took it out of the box and welded it in place. Jack works smoothly and now that I have a. new jack it is obvious that the old jack had been in bad shape for quiet some time. This new one is almost effortless.

Works flawlessly.



by:

Great jack only thing is check the grease,instead of putting it on the gears they just put a big blob in the top



by:

Works great



by:

I got 2 of these for a landing gear set up on my bumper pull. Customer service said there is no way to reverse gear to use as landing gear so i set them both to turn in same direction. These are by far the best price ive found. Compared to a local prices i basically got 2 for the price of one. Doesnt appear to have any sacrifice in quality either. Very heavy duty. It only took a few days to get them. Customer service is great and so is the product. If you want to see more of my set up with these jacks, you can view my trailer build videos on my online video channel carvings by levi.

  • Replacement Heavy Duty Trailer Jack for a Eby Gooseneck Trailer
    Thanks for the information and photos, Brock! For your application I recommend picking up the 10K Square Direct Weld Jack - Drop Leg w/ Spring Return # TJD-12000SP-R2NH and reusing your current handle and crosstube. This is a weld-on installation but that's pretty common when you start getting into these higher weight capacity jacks.

  • Is there a Jack to Replace My Bulldog Jack Part Number 182513?
    Hello TJ, Thanks for writing in, I am glad you found us. The Bulldog BD182513 has been discontinued, but the etrailer Square Jack # TJD-12000SP-R2NH is the closest replacement we offer.

It was also a fixed-leg design with no drop leg. The etrailer # TJD-12000SP-R2NH...

  • 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.

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...

    To get your Diamond C dump trailer back in working condition you'll need to swap out the entire jack as that internal drive screw isn't available as a replacement. For a replacement jack I recommend going with our etrailer Trailer Jack # TJD-12000SP-R2NH along with the Handle # TJD-12000-HD because we still have replacement parts for our trailer jacks in case you end up needing them. Also, the parent company of Pro Series is in a transition phase right now so there's no guarantee this...

  • Can Two Square Direct Weld Jacks 25-3/4 Lift - 10K Be Used Together
    The Square Direct Weld Jack part # TJD-12000SP-F2 can be used in tandem. The only thing you would need to do this 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. We don't have any cross shafts for this but you should be able to find the parts locally as it's just a steel pipe with holes drilled to pin the pipe to the...

  • 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 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.

  • Does Jack Drop Leg With Spring Return Require Manually Pushing the Leg Down
    Yes, you will have to manually push the drop leg down on the # TJD-12000SP-R2NH. Once you get it to the position you want you will re-pin it to keep it in place. This also means it will automatically retract when you pull the pin out so you don't have to raise it back up with your hand or foot.
