One Piece Products began in 2008 with the development of our signature one-piece kit for 1973-91 GM trucks. Since then, we’ve expanded our innovative designs to include other Chevrolet truck models. Our one-piece kits eliminate the vent glass assembly, giving vehicles a sleek, modern appearance. Chevrolet trucks hold a special place in our history, as the inspiration for this groundbreaking idea came from one of our own. Over the years, we’ve continually refined our kits, making significant improvements to ensure a seamless and user-friendly installation experience.
