How to Determine the Support Capacity You Need in Your Landing Gear

If you will be using this landing gear to lift and lower your trailer onto a hitch ball or kingpin, then you should choose the jack you need based on its lift capacity. But, if you are just using it to stabilize or support a parked trailer, then you should focus on the jack's support capacity.


Heavy-duty jacks like this one stabilize about 25% of your trailer's total weight when it's loaded up. For example, a 50,000-lb trailer has a pin weight of about 12,500 lbs. For these legs to work, you'd need a set of landing gear with a combined lift capacity of no less than 12,500 lbs. If you only have one jack that can get the job done, that's great! In fact, this should work more efficiently, allowing you to spend less time cranking.


Note: Do not use landing gear to lift your trailer during tire changes or service work, because doing so will exceed the capacity of the landing gear.

by:

The trailer jack I purchased has made it much easier to hook up my chevy to the trailer. The spring component designed to make lowering and raising the jack easier stopped working the second time I used the jack. It took several weeks for me to get the jack after I placing the order.



by:

The product arrived on time as was as advertised . The jack was easy to install and has performed flawlessly from the first day.
I would definitely purchase from etrailer again.



by:

Nice heavy jack to replace the one that was on my trailer originally.



by:

No Handle arrived with my order. Packaged poorly and the jack sustained damage. etrailer made it right and sent us the missing handle to the Jack. Although the plate to the top was severely damaged they didn't replace that. Which I ordered online for approx $X. which should have been covered by etrailer sending it without being properly packaged.

  • Are Replacement Rod And Nuts Available For A 2001 Circle J Riata Horse Trailer Front Jack
    The only rod and nut replacement we currently offer, part # TJD-12000-RODNUT, is a bit smaller than the one you have so the only option that we can offer would be a complete replacement of the jack. You'd want to check the GVWR of the trailer and choose a jack that's rated for at least 20% of the GVWR. For example, the Buyers Products Heavy-Duty 4" Square Jack w/Front Pin Drop Leg # 3370091415H can handle 12,000lbs and has 26" of lift capacity. It has a weld-on installation and comes...

  • Replacement 12,000LB Landing Gear Jacks For 30' Gooseneck Trailer
    We have the Buyers Products Heavy-Duty 4" Square Jack w/Front Pin Drop Leg # 3370091415H that matches the design of the jacks on your gooseneck trailer. We will only have the jack assemblies and will not have the crossover tube or handle extension. If those parts are also needed they will need to be fabricated from steel tubing you can get at your local steel supplier.

  • Recommended Replacement Jack for Exiss Horse Trailer
    I might have an option for you but I don't know what exact jack you have on your Exiss Horse Trailer. That said, they are usually welded so there's not really a bolt-on replacement. The Buyers Products Heavy-Duty 4" Square Jack part # 3370091415H is a good option to start with, it has a 12,000 lb capacity and features a weld-on install. I have attached a full list of our jacks below as well if this won't work.

  • Replacement Landing Gear Recommendation for Holland 48000SL Jack on a Donohue Gooseneck Trailer
    Hey Brad, thanks for reaching out! I really like the 12K Buyers Products Heavy-Duty 4" Square Jack w/Front Pin Drop Leg # 3370091415H to replace your Holland 48000SL because it gives you a little extra capacity and you're able to get 2 of these and use them as a set. We don't have a crossover tube for it, but these are pretty standard and you should be able to find one at your local trailer shop.

  • Replacement Trailer Jack For Rice Trailer That Currently Has Ram 14K Jacks
    The Ram 14K jacks don't have a replacement rod and nut available like the 12K # TJD-12000-RODNUT and are no longer available in that capacity. I recommend changing out your jacks for the 12K option. You can use the Bulldog Side Wind Jack Assembly - 12,500 lbs # BD182700 or the Buyers Products # 3370091410H or # 3370091415H as a replacement. These are all excellent products for the price to help your trailer function as intended.

  • Is There An Electric Motor Compatible With The Buyers Square Jack 3370091415H
    While we do offer several other powered jacks, we do not have a motor that is compatible with the buyers # 3370091415H at this time (July 2023). The only powered jack we have are either a-frame style like part # EJ-3527-BBX, or fifth wheel landing gear like # UF17-943010.
