The 6B Cummins is used in many applications including step vans,uniform and commercial delivery vehicles, industrial, agricultural & construction industry. We have recently added the industrial QSB offering to its product line.
During the building process torque plating methods for boring and honing to ensure block straightness, which reduces break-in time and crankcase pressure. In addition, we use OEM or equivalent pistons, rings,bearings, valves and gaskets, making sure that this engine will stand the test of time.
