First I want to make sure you verify your channel mount for the Demco Trailer Coupler #DM14040-81 has a 21K or larger capacity as often times they are less like the Demco #DM15349-52 which often times people look at and think it is a channel mount…

What you noticed is correct. The only difference between these two couplers is the color. The #DM15791-52 is silver and the #DM15791-81 is black. Even with a different color finish they both offer the same 500-hour salt spray rating.

Hey Brandon, the equalizer kit part #K71-449-00 will most likely work for you still but you'll want to measure the equalizers you have now to be certain. Measure the distance between the bolt hole centers of what you have now and if the are 7-3/4…

First you will need to remove the old hydraulic equipment. Remove the surge coupler or actuator, remove all the lines, and finally remove the brake assemblies. If you have 10 inch diameter hub and drums, you may need to replace those as well. If you…

Yes, you can so long as your Demco EZ latch coupler is cast like item #DM14040-81 or item #DM37ZR. The InfiniteRule Lock for Demco eZ-Latch Trailer Couplers item #IR66FR works great with these couplers whether they're being towed or parked.

Personally I prefer the Demco Trailer Coupler #DM14976-52 with the composite handle over the Coupler #DM15791-81 with a metal handle. I feel it is easier to operate as it does not have the safety latch like you get on the metal handle. Since most…

Hi Harvey; the DFMD35 series (same as your AFMD35121) has been discontinued. This leaves you with two options. You can either downsize to a 30k Btu unit or move up to the 40k unit. The 30k will fit in your existing space but you will have a little…

Based on the number you listed the correct hub/drum you need is the part #8-219-9UC3 which is a Dexter hub for 5,200-7,000 lb trailer axles that have an 8 on 6-1/2 inch bolt pattern.

I would use a protractor, see photo, place the protractor on the edge of the inside of one side of the trailer frame and the other inside edge of the trailer frame should be parallel with the 50 degree line on the protractor. Another way to verify…

Your lug nuts that you have on your 8,000 lb axles are designed to fit a 9/16 stud. That is not the size of socket you would need. Since lugs of the same thread size can have various socket requirements it would be hard for me to say specifically…
