Cummins 4B, 4BT, 4BTA 3.9L Inframe-Overhaul Engine Rebuild Kit (Natural Gas)

  • Availability:
  • OEM Number: RP934211
  • Brand: Reliance
    Brand Info x Close Reliance

    Every Reliance part is produced to exacting standards to ensure the same or better reliability as the original part. In fact, for older engines current technology is often so improved that the part we make available today may actually be better quality than the same part used to assemble the engine originally.

    New and remanufactured internal engine parts, complete cylinder heads and long block assemblies for agricultural and industrial applications supplied by RPP are warranted to be free from defects in material and workmanship under normal service and operating conditions for a period of one year from the date of installation without limitation on miles or hours of operation.

    Engine overhaul kits for heavy-duty on-highway applications supplied by RPP are warranted to be free from defects in material and workmanship under normal service and operating conditions for a period of two years from the date of installation without limitation on miles or hours of operation.

Cummins engines can be difficult sometimes in determining which parts you need. In order for us to better serve you, we require that the above fields are filled out. Many Cummins engines used a number of different cylinder liners, pistons, ring packages, gasket sets, and bearings. Because of this having the CPL number, engine model and engine serial number helps us ensure that you are getting the correct parts. If you have any questions or would like to speak to one of our friendly parts experts, give us a call 1-800-437-3609.
