DES is proud to offer a full line of heavy-duty, medium-duty, and light-duty DPFs and DPF accessories through our Redline Emissions Products brand, including clamps, gaskets, weld bungs, and sensors. We also carry brands like Durafit, Skyline, Filtertherm, GESi, W&L, and more.
Trucks manufactured before 2007 don’t have factory installed DPF filters. We take these vehicles and fit them with a system to meet emissions compliance standards.
Unable to make it to one of our shops? No worries! We have teams of technicians and a fully outfitted service fleet that can travel to your location. Having your vehicle’s retrofit service done this way can save you time and money.
At select locations, DES offers limited diesel repair services for heavy-duty diesel engines. The focus is primarily on emissions diagnostics & repair in addition to DPF cleaning. Our aftertreatment experts have the experience and tools to know what’s needed for your truck’s exhaust system.
You can trust our experienced techs and knowledgeable parts managers to get your rig back on the road as fast as possible.
