Minimizer Sleeper Cab Mats are available for new Cascadias MY 2018-2023. The mats are designed by scanning the interior measurements and angles of each specific make and model semi cab to ensure an exact fit, and include a retention hook mounted to the base of the stick shift to keep the mat in place. Made out of a proprietary thermoplastic that won't break or crack under extreme conditions, the textured surface provides a solid grip. Backed by a lifetime manufacturers warranty.
