Featuring a 12V electrical system, 7.2kW rated output, a 12-tooth pinion, clockwise rotation, and planetary gear reduction (PLGR) construction, this starter is designed to deliver high cranking torque for heavy-duty commercial vehicles and compatible equipment.

The unit cross-references Cummins, Delco Remy, Arrowhead, J&N, Lester, NSA, Unipoint, and WAI part numbers. Certain configurations may include a rotatable housing, an integrated solenoid, and additional starting-system protection features.

Before ordering, verify the original starter part number, voltage, mounting dimensions, solenoid position, and electrical connections.
