Availability of Replacement Gears for a Shelby 5759 Trailer Jack

Question:

I have a 92 foot Ranger bassboat with Ranger Trailer and it has a welded in Shelby model 5759 jack. does anyone sell the worm and inside gears or is there a replacement jack available from some company? the round up/down pole with the wheel is in good shape so just trying to replace the gears. Please let me know. Thanks,

We do have replacement jack options for you, but unfortunately we do not have any replacement gears for a Shelby jack.

I have attached a link to our selection of swivel jacks that you can filter through for the best replacement option. One of the most popular options that we have to offer is the Fulton F2 Swing-Up Trailer Jack # F1413040134 rated for 1,600 lbs.

This jack has a single wide 8" wheel that make it easy to maneuver and features an easy bolt-on installation that fits 3"x3: and 3"x4" trailer tongues.

I have attached a review video that you can check out to see how this jack operates.

Shelby trailer jacks have been discontinued for quite a while, so replacement parts are really hard to come by. The only resource at this point are used/second-hand retailers. So if you have a damaged gear your best option right now is to replace the entire jack with something like the Fulton option that Jon mentioned above. I also linked our full selection below.
