Standard features of the QSC include:

• Full-Authority Electronic Controls – Provide seamless integration with other components to optimize engine operation.
• Stiffer Block and Head – For reduced noise and vibration. Fluid circuits are integrated, replacing hoses and eliminating potential leaks.
• High-Pressure Common-Rail Fuel System – Allows multiple injection events for cleaner, quieter operation with consistent performance at every rpm. Also improves cold-weather starting.
• Wastegated Turbocharger – Delivers maximum power and torque.
• Mid-Stop Cylinder Liners – Reduce cavitation and improve rebuildability.
• Auto-Tensioning Belt Drive – Self adjusting for optimum tension, which increases fan, alternator and fan belt life.
• Heavy-Duty Roller Followers – Cam roller followers give the QSC superior durability and cam life.
• Two-Stage Dual Fuel Filtration – Provides a balanced level of particle separation to maximize fuel filter life and protect the vital fuel system components.
• Gear Housing Design and Front-End Support – The gear housing and accessories mount directly to the block for improved durability.
• Improved Piston Design – Symmetrical piston bowl combines with centered injectors to deliver optimal combustion.
• Heavy-Duty Lube System – Targeted piston cooling and increased lube flow to the power cylinder result in increased piston reliability and durability. Improved lube and bypass filtration system increase ring and bearing life by as much as 63%.
• Improved Crankcase Ventilation – Virtually eliminates oil carryover.
• Valve Cover and Gasket – Isolated design with perimeter bolting for better sealing and improved reliability.
