Durafit Guarantee

Dependability, uptime and service life of your diesel equipment is key to your success.

To ensure your DuraFit DPF will provide a long and reliable service life, CDTi put their DPF units through some of the most stringent testing and verification processes in laboratory facilities as well as real‐world testing.

They go through these processes to ensure your DuraFit DPF unit will meet or exceed OEM DPF performance requirements and provide exceptional DPF longevity in your heavy‐duty diesel equipment. That's why CDTi can back‐up your DuraFit DPF with an industry‐leading 2-year, unlimited mileage warranty.

DuraFit OEM replacement DPFs may cost slightly more, but they offer long‐term savings and peace of mind for the reliable operation of your heavy‐duty diesel equipment. When compared with the cost of lost productivity or repeated DPF replacement, paying a little more for the enhancements inside DuraFit DPFs is low‐cost insurance that pays dividends with the long‐term productivity of your diesel equipment.
