From the looks of the photo you sent it does not look like you have an OEM suspension system on your boat trailer. I recommend securing the suspension rail to the trailer frame in a more secure manner like drilling and using bolts so that it does not shift.

If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible.

You will want to also measure the distance from eye to eye of your old leaf springs and then pick a leaf spring with the same weight capacity of your trailer axles and is slightly shorter (around 1 inch) to compensate for the sag and wear of the old leaf spring. I have attached links to the leaf springs that we offer.

Leaf springs should be replaced in pairs to help keep your trailer stable while being towed.

I also attached a link to the suspension kits we offer for single axle trailers. You can measure your hangers and find replacements on our product page.

I have attached an FAQ articles that reviews trailer suspension components for you below to check out.
