Finding the right replacement mirror for your truck is easy with RETRAC west coast mirrors. This pyramid-back west coast mirror is designed to be an ideal OEM replacement for medium-duty GM trucks. It features 7" x 16" glass to provide a wide view, a universal stud mounting system to attach to any standard loop, and first-surface, electro-chrome glass to eliminate dangerous glare. It is constructed from stainless steel for excellent rust resistance, and it features a polished finish for a bright accent. It also features the RETRAC smart heater: a computer-printed, self-regulating heater that evenly and automatically defrosts the glass without the danger of overheating.
