To replace the springs on your travel trailer, we will need to know a few things. First, we will need to know if the springs are slipper style springs, like the 5-Leaf Slipper Spring w/ Hook End for 6,000-lb Trailer Axles # e67SR, or double eye springs, like the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # e78SR.

From there, you will need to measure your current springs. If you have double eye springs, you will measure from the center of one eye to the center of the other eye. The # e78SR, as an example again, will measure 25-1/4 inches from eye to eye. If you have slipper springs, you will need to measure from the center of the eye to end of the spring. The # e67SR will measure 27 inches long when measured in this way.

The last thing you will need to do is measure the width of the spring. This will only need to be done if you have a slipper spring though as double eye springs will all be 1-3/4 inches wide. Slipper springs can vary though and the # e67SR will be 2 inches wide.

Both of these springs are rated for 6,000 pound axles and, depending on the measurements you get, could be good options for replacements.
