Molded Boards are constructed from a single solid UV resistant molded polymer and are engineered to meet or exceed OE replacement needs. The mold shell is attached to a sturdy aluminum base board and features a channeled step area design in a classic O.E. style. If you feel like changing it up a little, choose the brighter option! Molded Lighted Boards include open-door activated lights that illuminate the step surface to improve visibility in dimly lit situations. For safety reasons and to ensure proper installation, it is recommended that wiring be professionally installed (wiring harness included).
