Dinex DOC/DPF Kits provide a complete aftertreatment solution combining a Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) in a single, convenient package?engineered for EPA 10-21 Class 6-8 trucks and buses where both components are replaced simultaneously.;;Replacing both the DOC and DPF at the same time is a common service practice?particularly when a failed DOC has contributed to accelerated DPF loading or damage, or when the vehicle has reached a mileage threshold that makes replacing both components cost-effective.
