Video Transcript for etrailer Trailer Jack JSP-100 Review

Today, we're going to be taking a look at a bottom support plate for a 2-1/4" outer-diameter A-frame jack with a capacity of 5,000 pounds. This support plate is going to add stability to keep your A-frame trailer jack from leaning under heavy loads. It's a bottom-mounted plate that attaches to the underside of your trailer frame. It's made from a sturdy steel construction. This is a weld-on installation. It's a nice raw finish for easy welding, so there's no prep work for it. This is designed to fit jacks with a 2-1/4" outer-tube diameter.

We can tell that by taking a measurement of the diameter of the hole right here at the center of the plate. It's going to be just a hair over 2-1/4". The exact measurement is going to be 2.29", but it is designed for a 2-1/4" outer-tube-diameter jack. Again, it's going to have a weight capacity of 5,000 pounds. A few measurements I want to go over with you real quick. The thickness of the plate is 1/8".

Again, steel construction. If we take an overall length measurement here at the back, that's going to give a measurement of 8-3/4". Here at the front, that length measurement is 5-1/2". The diagonal measurement right here, it's going to be the same for the other side. That's going to measure 3-7/8".

Then from front to back right here at the center, the straight-line measurement is 3-1/2". That's going to do it for today's look at the bottom support plate for 2-1/4" outer-tube-diameter A-frame jacks.

I used two of these to convert my side mount jack to an A frame jack without replacing my hitch receiver. With a few modifications they work great! Super happy! 726320

This is 1/8 inch steel So it’s really hard to weld. If they made it with a thicker material I think it would be a lot better. 713156

While these may be good to weld on, most of the trailer jacks that I have seen are the 3 bolt triangular style. These don't work well with them since the front part is too short to cover the entire bolt hole. So these would only be useful in a weld on style jack configuration, not a bolt in. 420122

Ask the Experts about this etrailer Accessories and Parts

  • Steel Thickness for A-Frame Trailer Jack Support Plates for 2-1/4 Inch Jacks
    The A-frame trailer jack support plates for 2-1/4 inch jacks are all approximately 1/8 inches thick. There are some manufacturer tolerances so one might be slightly thicker than the next. And models that are raw steel like # BD003135 are more uniform in size compared to the ones that are powder coated. I have included a link to the options. Not all of them are for 2-1/4 inch jacks and there is also a square one in there but the majority are for 2-1/4 inch round jacks.

  • Recommended A-Frame Jack Mounting Support Plate For Standard 3 Inch On Center Mount
    The Lippert Components # LC285318 uses a standard 3 inch on center bolt pattern. You will most likely need to drill some new holes in your coupler to allow for the standard mounting when replacing your trailer jack. I recommend the Bottom Support Plate for 2-1/4" OD A-Frame Jacks - 5,000 lbs # JSP-100 if you are concerned about the stability in that location with the additional holes.

  • Highest Lift for A Frame Trailer Jack With 5,000 lb Weight Capacity
    We have a jack that meets all of the requirements that you are asking about. The Round A-Frame Trailer Jack # TJA-5000S-B has a lift, or travel, of 15-5/8 inches. When this jack is fully extended, the bracket height it 24 inches. This jack also features an easily accessible grease zerk for maintenance and has a support capacity of 5,000 lbs. Since this jack doesn't come with a foot, I recommend using part # JF-1005H-Z to help stabilize your trailer. If you would like a bottom support...
