Frequently Asked Questions

Is there a core charge for this aftermarket emissions unit?

No, this is a 100% brand-new aftermarket component. Unlike remanufactured factory units, there is absolutely zero core charge, zero tracking paperwork required, and no need to spend money shipping your old, dirty unit back to us.

Does this replacement unit come with the necessary clamps and gaskets?

When you select the "Full Kit" option from the dropdown on this page, all exact-fit installation gaskets and heavy-duty alignment clamps required for installation are bundled and shipped directly with the assembly. Selecting the component-only option provides the bare unit without hardware.

How fast will my order ship out?

Orders confirmed before 2:00 PM Eastern standard time ship out from our closest regional fulfillment hub on the exact same business day. Free standard ground shipping is included to the continental United States, and expedited overnight air choices can be selected directly at checkout.

How do I verify this aftermarket filter matches my truck's setup?

You can verify fitment by identifying the original casting, housing, or tag stamp directly on your factory exhaust unit canister shell. If that number matches any of the cross-references listed on this page, or if your engine model and year line up with our application guide, it will bolt directly in with a perfect factory alignment.

SIGNS YOUR DIESEL OXIDATION CATALYST (DOC) NEEDS REPLACEMENT

  • Inability to initiate or complete manual parked DPF regenerations due to low face temperature across code sets 2888248 / 4965225 / Q621404
  • Raw unburned fuel dripping from exhaust joints or visual engine exhaust face oil fouling at the internal module inlet face
  • Active dashboard diagnostic trouble codes (DTCs) reporting low catalyst efficiency or abnormal upstream sensor readings
  • Unexplained increase in downstream DPF soot plugging frequency due to catalyst washcoat breakdown

*Note: Always verify exact vehicle compatibility using your vehicle's VIN number, emissions family descriptor tag, or the original stamped OEM part number on your catalyst module casing before placing an order.

California Shipping Notice: This product is EPA compliant but is NOT for sale in California and cannot be shipped to a California address.

Disclaimer: Product images are for reference only. Final components (filter, gaskets, clamps, sensor locations) depend on the selected configuration. Selecting the "Full Kit" option adds the explicitly listed installation components to your shipment. Price is for (1) DOC only.
