Make a list of the important elements of suspension to you. Sometimes trailers experience more issue with swaying back and forth, while others have a rough or bumpy ride.
Study the various upgrade systems and choose one that focuses on sway or bump, depending on what is more important to you.
Check the requirements on the suspension system. Not all systems are compatible with all trailers. If you are mechanically inclined, you might be able to make most of the systems work, but it is best to choose one that is meant for your set-up.
Purchase the suspension system of your choice.
Read the directions from start to finish. Gather all the necessary tools to complete the project before you begin.
Prepare the area, ensuring you have everything you need, as well as a large flat surface to work on.
Follow the directions and install the new suspension.
Hook the trailer up to your truck. Take the trailer just a short distance down the road to check the stiffness of the ride.
Make any adjustments to attain the ride you enjoy.
