Question:

I have a jet ski trailer I converted to carry my kayak but it’s about 2 feet short. I wanna put a swing away thingy in it so I can still store it in my garage. My tongue is 3”x3”. Do you have a swing away trailer thingy that fit that size?

Hey Kevin, how did the swing-away hinge kit work out on your jet ski trailer setup? Your experience could point others in the right direction who want to convert their trailers for kayaks too.

@JamesonCi Thank you for reaching I replaced the entire tongue with a 10’ piece which gave me an extra 4 feet up front, and added the swing arm to the tongue with no problem. I did this because if I was transporting my trailer with nothing on it, I could not see my trailer at all backing up. The swing arm helps me to be able to shore it without having any issues. The swing arm is strong, sturdy and fit the 3” s quart tubing with no problem. Being able to fit into my garage because of the swing arm is great since I have more than my car parking in the driveway. I’m really glad I came across E-trailer and discovered the swing arm. Its a great piece of equipment and helps make the storing of my trailer simple
