This injector is cross-referenced with a wide range of authorized OE numbers, including 10R-0957, 10R-2781, 10R-8500, 0R-4119, 0R-4300, 0R-4331, 0R-4894, 0R-9257, 103-4562, 117-0482, 118-8010, 118-9030, 140-8993, 159-2479, 191-3003, 211-3023 and 6I-3887, providing broad fleet coverage and simplified sourcing for global aftermarket distributors.

Built to industrial-grade standards, the injector features calibrated atomization, precision fuel metering, heavy-duty internal construction and remanufactured components validated through injector flow testing and leakage testing. Matched set availability and core return program compatibility support consistent cylinder balance during multi-injector overhauls. In service, the 10R-8501 delivers accurate fuel metering, correct spray pattern, stable injection timing and balanced cylinder performance, contributing to stable idle, clean combustion, strong pulling power, lower smoke output and reduced fuel waste in demanding operating conditions.

Typical applications cover Class 8 trucks, long-haul tractors, dump trucks, vocational trucks, heavy haulers, generator sets, mining support equipment and industrial diesel systems used across North America, Latin America, Europe, the Middle East, Africa, Southeast Asia and Australia. It fits Peterbilt, Kenworth, Freightliner and International platforms. Final compatibility should be verified by engine serial number, injector trim code, ECM calibration and fuel system configuration prior to installation.
