Go Rhino RB Series running board kits combine off-road styling with functional stepping platforms: generous RB10 louvers or RB20 bullet-stamped boards provide traction and help clear mud, ice and snow. High, tight mounting preserves ground clearance for trail use while offering a durable stepping surface. Built from 16-gauge zinc-coated galvanized steel with choice of textured black or bedliner coatings, these complete kits include mounting brackets and optional drop steps, and are covered by a Limited Lifetime materials warranty plus a 5-year finish warranty.
