Will Installing Higher Rated Leaf Springs on a Trailer Give it More Capacity.

Question:

I will soon be starting to building a house on wheels, I do have a 22 feet trailer with two 3500 lb. axles, My question is: if I add a leaf to the springs, or new springs, it will change the axles rate.

Expert Reply:

If you add higher rated leaf springs on your 22 foot trailer the suspension will have a higher capacity, but trailer capacities are more than just based on the spring rating used. Your capacity will only be as high as the weakest component in the setup. Other things to consider are, axle ratings, hub capacity, and frame capacity. Your best option would be to use 3,500 lb axle rated leaf springs since that is the capacity of your axles.

I attached an FAQ on trailer springs for you to check out also.
