Emissions Solutions

Grand Rock understands that regulations and emission standards on diesel trucks are inevitable and constantly changing, requiring truck exhaust to burn cleaner. However due to high temperature regeneration systems, Grand Rock also knows this can cause premature failure on certain exhaust components. Grand Rock’s Emission Solutions product line has you covered, from DPF V-bands and gaskets, to exhaust bellows and bellow kits. We also offer a ceramic lining for chrome stacks and other products which provides a thermal barrier protecting the chrome finish.
