We invite you to watch a video, download our product booklet, or just look around this page. See for yourself how REP DPFs are a value-add to your parts business. Curious to see if we have a particular DPF or look up a part# cross reference, then try our OEM Search tool.

Redline Emissions Products® offers aftermarket diesel particulate filters for the full range of Class 3-8 diesel vehicles. Our DPFs are built to meet OEM specs & work seamlessly with other emission components.

DPFs from REP come standard with the matching replacement gaskets and a 2-year unlimited mileage warranty.


One of the things that set REP DPFs apart is the higher level of quality. So, what does that mean?

Our extensive quality assurance process involves checking all welds, flanges, and Weld Bung ports. Any filters found to be out-of-spec are rejected.

The final step is to weigh, and flow-check the DPF. The weight (in grams) is noted on the DPF tag. The flow rate is documented and can be accessed with the serial number.

This provides peace of mind for resellers & distributors and reduces the chances of downtime because of a product failure due to defects.
