Detroit Diesel Parts

When the EPA introduced legislation lowering legal emission standards, Detroit Diesel introduced the 1-box aftertreatment system. The one-box combines the Diesel Particulate Filter (DPF), Diesel Oxidation catalyst (DOC) and Selective Catalytic Reduction (SCR) into one system. By introducing a catalytic converter, the 1-box keeps your diesel engine’s emissions within legal limits and the air you breathe clean. But your aftertreatment system has a shorter working life than your truck, and after 500,000 miles it may be worn out. That’s why Roadwarrior developed the first and only effective aftermarket 1-box, to complement our other Detroit Diesel aftertreatment parts. While a pre-cleaned reman replacement often fails soon after purchase, a brand new Roadwarrior part offers you up to 500,000 extra miles on your diesel engine.
