For us, classic doesnt mean outdated. It means tried and true. And when you combine the uncompromising quality of stainless steel with a tried-and-true design, you get side steps that will prove themselves over and over again. LUVERNE Side Entry Steps feature a classic, contoured design that mounts flush to your vehicles rocker panels and provides 5-1/2 in. of comfortable, non-skid stepping width. This package includes the running boards only and requires mounting brackets for a complete installation (sold separately). This set of running boards fits certain years of the Ford F-250 Super Duty, F-350 Super Duty, F-450 Super Duty and F-550 Super Duty Super cab (see application info for exact fitment).
