OEM Surplus DPFs/DOCs

We have a large selection of brand-new OEM-made DPFs and DOCs, as well as complete aftertreatment systems. From brands such as Cummins, Caterpillar, Detroit Diesel, etc.

Since these DPFs & DOCs are OEM, they are available in California, unlike aftermarket Diesel Particulate Filters & Diesel Oxidation Catalysts.
