Comnova 6-Inch Running Boards Compared
Material and corrosion protection
When choosing side steps, metal composition determines longevity against the elements. The COMNOVA 6" Running Boards for Silverado/Sierra Crew Cab use heavy-duty galvanized steel with a black powder-coated finish and glitter accents. Its brackets feature plastic protective covers to help block rust formation. In comparison, the COMNOVA 6-Inch Stainless Running Boards for Ram Crew Cab are built from high light stainless steel. This stainless steel build resists salt spray corrosion and withstands UV radiation exposure without surface discoloration. Both products incorporate anti-slip plastic step pads for foot traction. If you encounter road salt or severe weather, the stainless steel construction on the Ram board provides superior native rust resistance over powder-coated galvanized steel.
Compatible truck fitment
Your truck platform dictates which side step set will bolt up correctly. The COMNOVA 6" Running Boards for Silverado/Sierra Crew Cab mount to 2007 to 2018 Chevrolet Silverado and GMC Sierra 1500 trucks, as well as 2500HD and 3500HD crew cabs through 2019. It does not fit diesel engines or classic trims. The COMNOVA 6-Inch Stainless Running Boards for Ram Crew Cab fit 2009 to 2018 Dodge Ram 1500 crew cabs, Ram Classic models up to 2026, and heavy-duty Ram 2500 and 3500 crew cabs up to 2026. Both models use a patented slider design that adjusts forward and backward along the rocker panel, but each serves an entirely different vehicle brand.
Step bar length
Stepping area coverage along the rocker panel depends directly on overall board dimensions. Both options provide a 6-inch stepping width and a 2-inch profile height, giving you a broad stepping surface. However, the COMNOVA 6" Running Boards for Silverado/Sierra Crew Cab measure 86 inches in total length. The COMNOVA 6-Inch Stainless Running Boards for Ram Crew Cab measure 82 inches in length. That gives the Silverado and Sierra running boards an extra four inches of span underneath the doors. If you want maximum cab coverage along the sides of your truck, the COMNOVA 6" Running Boards for Silverado/Sierra Crew Cab deliver more total length for passenger footing.
Product weight
Weight affects how manageable side steps are during a solo garage install. Both products feature a direct bolt-on mounting design that requires no vehicle drilling, along with a 500 lb weight capacity per side. The COMNOVA 6" Running Boards for Silverado/Sierra Crew Cab weigh 49.6 pounds across the package. The COMNOVA 6-Inch Stainless Running Boards for Ram Crew Cab weigh 47.6 pounds. That makes the Ram model two pounds lighter overall. When you lift and position the brackets and bars underneath the truck frame, the lower weight of the COMNOVA 6-Inch Stainless Running Boards for Ram Crew Cab makes holding parts in alignment slightly easier.
Catalog sizing options
Product line variety matters if you own different cab configurations or want custom dimensions. The COMNOVA 6" Running Boards for Silverado/Sierra Crew Cab belong to a product line featuring 12 variations. These include 2-inch and 3-inch profile heights, finishes in black and stainless steel, and fits for Silverado crew cabs, double cabs, diesel models, and Colorado trucks. The COMNOVA 6-Inch Stainless Running Boards for Ram Crew Cab belong to a lineup with 7 variations, restricted to a 2-inch height across Ram crew and quad cab configurations.
