Sleek Step Assistance Without Bulk. The RB20 Slim Running Boards provide a convenient stepping surface for vehicles with higher ride heights, helping passengers enter and exit safely. Their slim profile hugs the vehicle’s rocker area, preserving approach angles and minimizing exposure to off-road obstacles. The textured black finish adds a rugged look that complements both work-truck and street styling.

Heavy-Duty Construction for Lasting Performance. Built from high-strength steel tube and finished in a durable textured powder coat, these boards resist rust, scratches, and impact from road debris. The non-slip step pads channel water away and maintain traction in wet or snowy conditions. All mounting brackets and hardware are zinc-plated to prevent corrosion and ensure a secure, rattle-free installation.

Installation. Locate factory frame-rail mounting points, attach Go Rhino mounting brackets with supplied bolts, slide the running board into bracket slots, adjust for level alignment, then tighten all fasteners to the specified torque.

Application. The Go Rhino RB20 Slim Running Boards; Textured Black fit 2015–2019 Sierra 3500 HD Crew Cab models equipped with the 6.0-liter engine.
