Question:

We have been ordering the 5000 lb Curt brand trailer jack with PN: PS1401440303. Searching that same PN on the website now returns the 7000lb RAM brand jack TJP-7002S-B. Is this a permanent replacement or is the Curt jack still available? I ask mainly because the pin holding pipe that comes in a different size which causes complications on our end. Thanks!

Thanks for reaching out Tegun!

Apologize for the confusion, the original CURT 5,000 lb Swivel Jack (part number PS1401440303) is no longer available through us, which is why that part number now redirects to the RAM 7,000 lb Swivel Jack # TJP-7002S-B.

I can check to see if we have a closer replacement.

Could you tell me the diameter of the locking pin and the outside diameter of the mounting pipe on your CURT jack?

With those measurements, I'll compare them to the swivel jacks we currently carry and see if there's a better match than the RAM jack.

The pin is 5/8" and the OD of the mounting pipe is 2". Thanks!

@TegunT, thanks for the measurements! I compared them to the RAM 7,000 lb Swivel Jack #TJP-7002S-B and you were correct that the mounting pipe is different. Your original PS1401440303 uses a 2" OD mounting pipe with a 5/8" locking pin, while the # TJP-7002S-B uses a 2-1/2" OD male mounting pipe and use a 5/8" locking pin. I'm going to use your 2" OD pipe and 5/8" pin measurements to narrow down the swivel jacks we carry and find the closest replacement. The dimensions for # TJP-7002S-B: Pull pin diameter: 5/8" Pull pin length: 3-15/16" Male pipe welded to the jack: 2-1/2" OD / 2" ID Female pipe welded to the trailer: 3" OD / 2-1/2" ID Pin hole: 5/8" on the compatible pipe mount.

@JamesD Do you guys carry a similar jack with a 2" OD pipe or is the 2-1/2" RAM jack the closest you now carry?

@Tegun Hi Tegun, James was promoted so I am taking over his answers! The closest option we have is actually the Trailer Valet JX Drill Powered Jack - Pipe Mount - 14-1/2" Lift - 1,800 lbs part # TV35FR. You will lose some lift but the weld on pipe mount is 2". This is the only one I was able to find with that diameter pipe mount.
