The ultimate accessory is back, and it complements today's performance-oriented trucks. Mach-Speed has brought back one of the most popular accessory of the 80's and 90's for the full-size pickups with its ABS rear window louver. The ABS louvers are designed to keep your truck cooler inside while making it look ""COOL"" on the outside and provide you some sense of privacy especially on the trucks with an OEM slider. With the styling features of our aluminum rear window louver makes this an excellent option for your performance vehicle.
