Cummins ISX and QSX Engine Parts – Crankshaft Section

The Cummins Crankshaft is the central component of the ISX and QSX engines, transforming the linear motion of the pistons into rotational force that drives the engine’s output. Built from forged steel and precision-balanced for smooth operation, this crankshaft features a 12-bolt nose and 12-bolt flange design for superior strength and durability. It’s engineered to withstand high combustion pressures and extended duty cycles, making it ideal for heavy industrial, power generation, and marine applications.

To ensure proper installation and long-term performance, Diesel Pro Power offers a complete range of complementary components. The Upper and Lower Gasket Sets provide reliable sealing for engines with or without EGR systems, preventing oil and coolant leaks around key interfaces. Crankshaft Shell Sets are available in both standard and 0.10 mm oversize options, ensuring precise bearing clearances and consistent lubrication between the crankshaft and block.

The Front and Rear Crankshaft Seal Kits, each including both seal and sleeve, protect against oil leakage at critical sealing points, maintaining system cleanliness and preventing pressure loss. For vibration control, the Vibration Damper is designed with 12 mounting holes, absorbing torsional forces to extend crankshaft and bearing life. Supporting parts like the Gear Housing Gasket, Flywheel Housing Gasket, and Front Cover Seal Strips complete the assembly, ensuring a tight, leak-free engine build.

Together, these components restore balance, compression integrity, and power delivery in Cummins ISX and QSX engines—trusted by professionals who depend on Diesel Pro Power for precision-fit, premium aftermarket engine parts worldwide.
