How to Measure Your Trailer Leaf Springs.

Your trailer should be unloaded when measuring. Match the shape and type of the existing spring. It will be a double eye, slipper to open eye end, slipper to hook end, slipper to flat end or slipper to radius end). Measure the length of the spring (see diagram) when the spring is not under load, this is the length of the spring. Count the number of leaves, each layer of spring metal is considered a leaf.

Be sure to measure from the center of the attaching eye in a straight line to the middle of the other eye or contact point, except radius end which is measured from eye to end of spring.  The inside diameter of the bushing in the attaching eye of the spring, I. D. Bushing, needs to match the shackle bolts used to mount spring to hanger. 9/16″ is the most common size, but some trailers use 1/2″ bolts. 

Also note that spring capacity is given per each spring-thus a 4,000 lb. rated axle should be matched with two 2,000 lb. or higher capacity springs.
