Cummins 5.9L QSB/ISB Diesel Engine
The 5.9L QSB/ISB Cummins is used in many applications including walk-in vans, buses, yard tractors and conventional cabs. Reviva also offers this engine in the QSB format for construction and industrial applications.
Reviva utilizes torque plating methods for boring and honing to ensure block straightness, which reduces break-in time and crankcase pressure. In addition, Reviva uses OEM or equivalent pistons, rings, bearings, valves, and gaskets, making sure that this engine will stand the test of time.
All Reviva engines are assembled in the USA.
