Vehicle Fitment Guide

Direct drop-in fit for pre-2007 trucks running a standard horizontal (under-chassis) exhaust setup:

  • Engine Compatibility: Cummins ISC and Paccar PX8
  • Common Applications: Pre-2007 medium-duty box trucks, dump trucks, vocational trucks, and regional day cabs.

Signs Your Diesel Particulate Filter (DPF) Needs Replacement

  • Unprompted dashboard diagnostic trouble codes (DTCs) pointing directly to poor soot regeneration efficiencies or excessive backpressure faults.
  • Frequent, uncompleted active or forced regeneration cycles that fail to lower soot load values across the filter matrix.
  • Unexplained commercial engine backpressure spikes or noticeable horsepower/fuel economy deterioration under loaded trailer pulls.
  • Visible black soot buildup inside the exhaust tailpipe indicating internal substrate cracking or structural bypass failure.

Note: Pictures are for reference only Always verify exact vehicle compatibility using your vehicle's VIN number, emissions family descriptor tag, or the original stamped part number on your filter unit casing before placing an order.
