...Hi, Im looking for more information explaining achieving the 21,000-lb weight capacity on the Demco Trailer Coupler - Cast - Adjustable Channel - eZ-Latch - Black - 2-5/16 Ball - 21K using the 4 5...

Hey Kolin, that part number BC21014 is actually the part number for a Demco coupler decal and not for an actual ball mount. If what you have looks just like the part #DM15945 I would say it's a pretty safe choice for a replacement. Otherwise if…

Hello Cody, I was able to get the instructions online for the Rough Country Air Bags, I do not see how they will work together. I have attached a picture where I highlighted in a nice etrailer yellow where the Country Air Bag is installed where the…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

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…

Based on my research, the Trailer Hub and Drum Assembly - 8,000-lb E-Z Lube Axles #AKHD-865-8-EZ-K will be a replacement for the 90865 Rockwell hub and drum. Both of these hub and drum assemblies are 12-1/4" diameter, have an 8,000 lb capacity,…

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.

Good question; the bolts in the Hardware Kit for Demco Adjustable Channel Mount Couplers #DM6166 should be torqued to 150 lb-ft during install of a Demco coupler like #DM14040-81 to a bracket like #DM66134.

Hey Mike! The Blue Ox Base Plate Kit item #BX2170, that fits your 4WD 1999 Ranger, is compatible with other brands of tow bars if you use an adapter. I have listed which ones you'll need below: Roadmaster - BlackHawk 2 All-Terrain, Nighthawk, and…

For your bearings, I recommend the etrailer.com Replacement Trailer Hub Bearing #LM67048. For your seals, I can't find the part number or dimensions anywhere, so if you send me dimensions of inside and outside diameters, I'll do what I can to…
