About Extang Parts & Accessories
When you hear the phrase Extang Engineered it really means something. It began when our values and integrity met bold engineering excellence. A product that is so well designed, and built to such demanding exact standards, that it performs beyond the truck owner's highest expectations. Engineering is at the heart of why Extang is the number one selling tonneau brand in North America. Extang was first to introduce many of the styles and features evident in the tonneau industry today. Since 1982, Extang continues to lead the industry with innovation, quality products, the best warranties and customer support. We believe our leadership position is also earned by a few enduring principles: hard work, relentless pursuit of product quality, and most important: paying close attention to our customers' needs. We are fully committed to bringing products to the market that will enhance the utility, convenience, and appearance of your truck.uck.
