OEM Surplus DPFs/DOCs

We have a large selection of brand new OEM made DPF's and DOC's, as well as complete aftertreatment systems, including Cummins and Detroit One-Box assemblies.

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