The Go Rhino RB20 cab-length running boards in textured black offer aggressive, off-road styling while providing a wide, full-length step and protection for vehicle sides. Perforated holes in the 7.5" board surface help prevent mud, ice and snow buildup while delivering maximum traction for safer footing. Constructed from corrosion-resistant 16-gauge steel and mounted high for added clearance, RB20 kits include mounting brackets and drop steps, and are backed by a Limited Lifetime warranty on materials plus a 5-year finish warranty on textured black.
