Trailer Leaf Springs
When replacing worn or broken trailer leaf springs, be sure to measure old springs as noted in the diagrams. Worn trailer springs will be longer than a new spring due to wear. Also, the given dimensions are for identification purposes only. Slight dimension variances should be allowed for due to spring manufacturing tolerances.
Note: If the trailer's axle is rated for 3,500 lbs then the needed leaf spring would only be rated for 1,750 lbs. The spring on the other side of the trailer makes up the difference. Also "replacement in pairs" is recommended for proper axle alignment and suspension performance.
