NOW® AFTERTREATMENT WARRANTIES

We also offer NOW® warranties on Cummins Ultimate Aftertreatment Service Kits for select engines. These warranties must be combined with the purchase of a NOW engine overhaul or ReCon® engine extended coverage of equal or greater duration. Quick and Premium Aftertreatment Service Kits are not eligible. The warranty covers all parts in the kit, requires all parts be installed and does not provide coverage for replacement parts outside of the kit. An exception is the Selective Catalytic Reducer (SCR). If an SCR is purchased and installed and all other NOW aftertreatment requirements are met, the SCR will also receive coverage.
