The Spring Seat Measurement is very important to ensure the safe and proper installation of this axle. If your Spring Seat measurement does not fall into the specified range, we cannot guarantee the successful installation or performance of your axle. Using a spring seat measurement that is too narrow will likely lead to your axle bending. Using a spring seat measurement that is too wide will lead to your tires rubbing on your trailer frame and/or leaf springs. Please verify that your Spring Seat Measurement falls into the range specified to avoid any problems.
