From a single-bay barn to a 25-bay campus, Kleyn Mobile Repair has always been fuelled by founder Joe Kleyn’s hands-on passion for engines and honest craftsmanship. Whether it’s an emissions issue on a Class 8, a DOT inspection for a box truck, or a full pump overhaul on a pumper, we have a bay—and a master-certified tech—ready.
