Can I Use a 2-inch Square Block Between Spring Seat and Spring for Additional Trailer Height

Question:

Can a 2inch square block be added between the spring seat and the spring to provide additional trailer height?

While a 2-inch block would provide additional trailer height, I cannot recommend doing so because it will result in less suspension travel or deflection.

Changing the height of a trailer can affect the center of gravity and cause the trailer to have more sway in wind or when large trucks pass. To change the height you will have to remove the existing hangers and replace them with longer hangers. This could involve grinding off the old hangers and welding new ones in place.

The best and safest suspension is the way the trailer was originally manufactured. The trailer manufacturer will have tested the trailer with the original suspension setup for adequate braking and handling performance.
