    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.

    Remanufactured clutch and non-engine parts are warranted to be free from defects in material and workmanship under normal service and operating conditions for a period of six months from the date of installation without limitation on miles or hours of operation.
