Accurately measuring your trailer springs and choosing the correct replacements is important for the function of your trailer and will make the job of replacing them much easier. Using replacement trailer springs with the correct length will keep the axle in the same position, eliminating the need to move fenders or suspension components like spring hangers or equalizer hangers. Matching your weight capacity, arch, and leaf count will keep the ride height of the trailer the same and keep the ride characteristics the same. Taking the correct measurements and matching your existing trailer springs will get your trailer back on the road quickly and with fewer headaches.
