Question:

I am trying to buy gear kit number F0933306S00 after watching your Fulton trailer jack gear replacement video. However, it doesnt show this part on your website. Is there a new part number for it. I have a Fulton 2500lb boat leg jack, square tube. Thank you

Hi there Jason!

I have a solution for you, but the Fulton gear kit F0933306S00 shown in that older video is unfortunately no longer active, and I’m not seeing a current replacement gear kit that directly supersedes it.

Since replacement parts for these older 2,500 lb Fulton square-tube jacks are pretty limited, replacing the complete jack will likely be the best option.

For a similar square-tube replacement, you could use the etrailer 2,500 lb jack # MJSQ-2500B.

If you'd rather switch to a swivel-style jack, the Dutton-Lainson Boat Trailer Jack w/ Wheel # DL22560 is another option. It uses a weld-on mounting bracket and swivels up out of the way for travel.

Sorry we didn't have exactly what you were looking for; it is unfortunate when parts start being unavailable for certain products. What type of boat and boat trailer do you have?
