Heavy duty injectors remanufactured by Flight Diesel, a partner offering top notch heavy duty and medium duty products. We are offering remanufactured Cummins ISX fuel injectors. All injectors are thoroughly tested to assure optimum quality. The remanufacturing process involves a complete disassembly and ultrasonic cleaning. Mating surfaces are lapped and each injector features nozzles that are extrude honed to factory flow specifications. Extrude honing is a method that smooth's and finishes rough surfaces, and is specifically used to removea burrs, polish surfaces, form radii, and accomplish a like-new finish and flow. Injectors are air gauged for tip seat leakage, valve operation, plunger and barrel leakage, and timing plunger operation.

There is no difference between the old style and new style spring retainer. Either one can be used without any issues.
