Where this trailer fits.
Start with the actual model
SmithCo’s SX3-4234 reference uses a 34-foot tub. The manufacturer also lists the SX3-4636 with a 36-foot tub. Western model codes and frame configurations can differ from the reference table below.
Compare more than axle count
Review axle positions, tires, suspension, tub construction and tarp equipment. For an SX3 or SXL3 listing, ask for the build sheet to establish the differences; the model suffix alone is not a specification.
Questions before you choose.
Are SX3 and SXL3 listings interchangeable?
They belong in the three-axle comparison, but their equipment should be checked individually. Ask for the actual dimensions, tires, axle arrangement and build sheet. Confirm the equipment on the trailer you are considering.
How do I check SX3 availability?
Matching live listings appear on this page, with available and incoming quantities shown separately. If none appear, send your required configuration and target date so sales can review sourcing options.
Bring us the application.
