Truck EGR & DPF Repair in Polk City, FL

Truck After-treatment Repair in Polk City, Florida

Black exhaust might look cool, but diesel emissions aren't. To keep your heavy-duty truck compliant, diesel emissions systems are complicated and necessary. They play a huge role in keeping your truck compliant and operational. When components like the EGR valve or DPF filter fail, you'll notice reduced power, a loss of fuel efficiency, and even engine shutdowns. None of which are ideal if your business needs you rolling.
