How to Pick Out Landing Gear for Trailer Based on Mounting Bracket Dimension

Question:

Hi, I am looking for a set of trailer landing gears made from 3inch square tubing with around 19inch of travel and have a side drive. Most of these are of a 4inch square tube construction. Thanks

The easiest way to pick out replacement landing gear sets is to go by the distance between the brackets either on the trailer or on the legs themselves so that you can pick out a set that will match up to the trailer without needing modifications.

Otherwise you could just have the brackets removed from your trailer by a qualified welder and then install the brackets that come with the Bulldog Tandem Landing Gear Set # BD500162. Either way this landing gear set would work well for you, you just might have to have the brackets of your trailer removed and then install the brackets of the # BD500162.

I attached a picture that shows the dimensions that this landing gear set would fit with.

The jacks would be the correct replacement for Lippert, Venture, and Atwood landing gear, as well as those from a few other manufacturers. The sure way to tell is that if the distance between the mounting brackets (underside of top bracket to top of lower bracket as shown in the diagram) is 17-1/2 inches. If this is the case, the landing gear should fit just fine.

If your frame clamps are instead 20-1/4 inches the Ultra Fab part # UF17-943010 would be a direct replacement.
