Dee Zee Hex Series Side Steps (board) - The Hex Series Side Step is made of extruded aluminum and overlaid with textured black powder coat protection to stop corrosion in its tracks. NRT (No Rust Technology) is a specially developed additive that increases corrosion protection within the powder coat. The integrated channel design allows you to adjust the position of the cast aluminum drop steps for customized placement. The cast design provides a larger stepping surface at each door for superior traction. A universal board combined with custom fit brackets (sold separately) creates the perfect look. Required custom fit bracket kits sold separately to fit the make and model of your truck to eliminate drilling. Extended Cab - 6" x 73" - Texture Black.
