http://Universal-Nissan.com/2015-altima.htm 407-926-7000 Frontier's full-length, fully boxed ladder frame is built for rock-solid performance - on, and off-road. It's made of impact-resistant materials that are both durable and stylish, like super-high-tensile-strength steel, and chrome on the rear bumper and front grille. Rear privacy glass adds a touch of attitude, while keeping it cool inside, and a tailgate-mounted rear spoiler helps reduce drag. It all amounts to a rugged exterior that's ready for whatever you dish out.
