The Go Rhino RB20 Slim Line Running Boards are heavy-duty side steps designed for the 2007-2021 Toyota Tundra Crew Max 4DR. Crafted from 16-gauge zinc-coated galvanized steel, these boards combine durability with a sleek, slim profile that fits closer to the cab, providing increased ground clearance for off-road adventures.

The modern bullet-stamped aesthetic measures 5 1/2 inches at its widest point, narrower than the original RB20, making them ideal for trucks, Jeeps, and SUVs seeking a streamlined look. The kit includes brackets for straightforward installation and is backed by a Limited Lifetime warranty on materials and construction, with a 5-year warranty on the textured black finish.
