Walker Z-502-1 Z-Series 1938 Chevrolet Radiator

							                        

                                                        
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. 
See Application tab for application information.
