Raising the Height of a Tandem Axle Boat Trailer with Leaf Springs Mounted on Top of the Axles

Updated 05/09/2016 | Published 05/08/2016

Question:

I have a tandem axle boat trailer that scraps at the top of the boat ramp when pulling the boat out of the water or putting it in the water. I would like to raise the trailer 1-1.5 inches to fix the problem. The trailer already has over axle suspension and need some advice on how to lift it.

Since the leaf spring stack is already on top of the axle on your boat trailer you can raise the height by having taller hangers welded on. I have included a link to our trailer suspension hanger main page for you.

Most trailer hangers need to be welded on. Welding should be done by a professional welder.

Another option is to use taller tires on the trailer provided that there is enough clearance above the existing tires to go to a size larger enough to fit your needs.
