Custom Metal & Plastic Leveling Shims


Iron Horse Engineering manufactures standard and custom leveling shims in metal or plastic materials designed to set proper rail elevation. Iron Horse custom shims, used under rail plates and DF fasteners are fabricated in various thicknesses and sized to match the fastener and rail support structure. Ironhorse Engineering understands the critical importance of shims and pads to provide support and leveling under the rail fastening system. Our custom abilities allow us to offer a variety of options, including, custom thickness, custom hole placement, UV stability, engineered materials, rail cant, electrical isolation, integration with isolated bushings, or use as slobber plates.
