Hello Angela, I can definitely point you in the right direction. Sundowner does not list exactly what kind of jacks they use online, but looking at pictures of these trailers online, the front jack on the Sundowner horse trailer looks very much like the Square 2-Speed Jack # e79FV. This jack has a 28" retracted height and 40-1/4" extended length, so you will want to compare this to the current jack and make sure it will be adequate. Also confirm that the 12,000 lb support capacity is enough for your specific model of trailer. If you need something different, just let me know and I am happy to look in to it.

Hi Angela, did the square 2-speed jack end up being a good fit for your Sundowner trailer? It’d be great to hear how the size and lift worked out for your setup. Your update could make it easier for the next person with a similar trailer.
