Some of our Painted Steel Trailer Axles come with Pre-Mounted Spring Seats for specific measurements. The Axles listed without pre-mounted spring seats will include the spring seats for you, the customer to weld to your specific measurements.  It is very important that you do not weld your spring seats outside the range listed. Using an axle to long may cause a leverage issue, leading to pre-mature bending or damaging to the ends of the axle. An axle that is to short will cause the tires to rub on the frame of the trailer.  

Check the Hub Face Measurement and overall measurement below, as well as the if the Axle comes with pre-mounted spring seats. This Axle features industry standard 4 " Drop Spindles, which allow for the frame of your trailer to ride lower, for easier loading and un loading.

                -Hub Face measurement refers to the outside face measurement, from one trailer hub across the axle to the outside face of the trailer hub across from it.

Spring Seats Are Not Welded to the Axle ( But Are Included) - Spring Seats need to be Welded on the Axle with the Centers measuring between 68" - 70". Using Spring Centers outside this range will effect the strength and fit of the axle on the trailer.
