Factory Replacement 6.9/7.3 IDI Injectors
The only IDI injectors with a 5 year unlimited mileage warranty, the Classic Diesel Design's stock replacement injectors are the go-to for anyone looking for an affordable, high quality rebuilt replacement injector set pressure matched to within 50 psi.
Featuring stock OEM nozzles and pop pressures, this is recommended to be matched with any new injection pump with less than 100cc of output.
For IDIs running more than 100cc we recommend the stage one injectors for improved egts, mileage and performance, however all CDD injection pumps are tested, flowed and spec’d with stock nozzles, meaning stock injectors can be used with any of our pumps and will output as advertised, stage one injectors simply allow for more fuel to enter the pre-chamber quicker, which improves combustion and fuel delivery from the injection pump over the stock injectors.
All Classic Diesel Design's injectors come with viton o-rings, and copper washers already installed.
Stock injectors require cores and have a $100 refundable core charge. If you are sending your cores afterwards, your core charge will be refunded once the set has been received and passed inspection for damage to the threads or injector bodies.
Inventory count denotes complete sets (of all 8 injectors) available for exchange and same day shipping.
- If you would like to save on the core charge by sending cores upfront, the exchange injector set will be shipped immediately pending core reception if exchange units are in stock.
- If no inventory is shown for exchange sets, the option to send cores upfront for rebuilding will still be available, and the new set will be shipped as soon as the next batch has completed our proprietary rebuilding, pressure matching and testing processes.
- Injector batches are often completed in irregular patterns as replacement component availability, ordering volume/batch size, core availability and labor availability for rebuilding are not constant so batches are not completed on a regular enough pattern to estimate exact turnaround times when out of exchange units, however we do everything we can to always maintain our stock injector inventory for immediate shipment year-round as well as a large core bank (See core buyback program) to minimize anyone’s down time.
- Stage One injectors typically can run out of exchange units stock during periods of high demand and can have extended rebuild times due to nozzle modifications lead times.
