Replacement for Shelby Jack on Boat Trailer

Question:

I have a shelby jack for my boat trailer. Is there a replacement jack that can use the welded piece on my trailer with the center bolt thru?

Hey Andrew! Since it is a bolt-thru you can use the Fulton Boat Trailer Jack w/ Wheel # F1411300301 as a replacement. This typically mounts on the # P9012-00 which is a 4-1/2" square bracket with pin holes 3" apart on center. If you don't want to worry about using the old bracket, or that doesn't match up with what you have, you could also grab a bolt-on option like the # FXP15L and put it next to the old mount so you don't have to cut and weld.

Hey Andrew, how did the Fulton boat trailer jack work out with your existing welded bracket? Your update could make it easier for others trying to reuse that same style mount.
