The 6.5" Black Sawtooth Running Boards are the latest running boards series from Raptor. These boards are manufactured from lightweight, aircraft-grade aluminum and finished in a textured black finish. Each board features a 6.5" wide step area and reverse punched serrated holes along the entire length of the board for maximum grip. The Raptor 6.5" Black Sawtooth Running Boards are also capable of supporting up to 400 Lbs. These boards feature the slide track mounting bracket system which allow you to adjust the positioning of the boards along the vehicle for customized fit, as well as the ability to customize your truck with a different style of slide track steps without having to change the brackets. Additionally, Raptor backs these boards with their limited lifetime manufacturer warranty on materials and craftsmanship, as well as their 10-year limited warranty on the finish.
