Round A-Frame Trailer Jack for 14,000 lb Trailer  


Hello, I’m looking at purchasing item #BD44150WQ317 or it’s equivalent with the round jack hole mount. The problem I’m having is being able to locate a properly weight rated jack. The one on your website is only rated for 3k pounds. The trailer I’m putting this on is a 1976 tri-axle horse trailer that has a GVWR of 14k. Of course it won’t haul horses anymore, but I plan on converting it into a heavy haul firewood trailer which means at any given time I might have 4-6 cords of firewood on it and I need the jack to be able to support it loaded in case I don’t have time to unload prior to uncoupling. The jack that was on it was a round jack, but that one has since rusted out and broken. I’ve thought about putting a weld on square jack, but I don’t believe I have the room to weld it on. Could you send me your thought and any product ideas that would suit me. Thanks for your time and making me a very satisfied customer with my previous purchases.

We can definitely help you out here, but let's start with the coupler. You mentioned Bulldog Heavy-Duty Cast Head Coupler with Wedge Latch # BD44150WQ317 but that you had a round jack on your trailer. This coupler has a hole for a square jack so instead, I recommend the Bulldog Heavy-Duty Cast Head Coupler with Wedge Latch # BD44150W0317.

This is the same coupler but has a round hole for a round jack.

Then for the jack, the great thing is that for an A-frame jack, its capacity only needs to support the tongue weight rating of your trailer, and most have much higher capacities. Tongue weight is often 10% to 15% of a trailer's GVWR, so for a 14,000 lb trailer the tongue weight is going to be in the 2,000 lb range, so you have a recommendation for you.

I recommend the 5,000 lb jack with 15" of lift by etrailer # TJA-5000S-B. This jack has a higher capacity than you need which will make the lift easy and will put less strain on the jack. Then I suggest adding the footplate # JF-99.

You would use the same foot plate for this jack. I've added links to video reviews for you to check out as well.
