    Maximize your radiators' effectiveness with a tight-fitting fan shroud. Use of these shrouds has produced temperature drops of up to 30 degrees!

    Walker shrouds are vacuum formed from a very dense polyethylene. This high-impact, heat resistant material has a lightly textured, semigloss black finish. The cooling fan hole is not cut out so the installer can tailor that to the exact fan location and diameter.
