CP Piston Diesel Set Dodge Cummins 5.9L - Bore (4.035in) - CR (15.25) - CH (2.786)

Forged from high-strength aluminum alloy, these CP Pistons are built to handle the demanding conditions of a Dodge Cummins 5.9L diesel engine. The 4.035-inch bore size is a direct replacement for stock applications, while the 15.25 compression ratio is optimized for enhanced performance and efficiency in diesel powerplants. The 2.786-inch compression height ensures proper piston-to-valve clearance and deck height when paired with appropriate connecting rods and crankshafts.

These pistons feature a robust construction designed to withstand the higher cylinder pressures and temperatures common in diesel engines. The specific forging process results in a well-built component that offers improved durability over cast pistons. Each piston is precision-machined to exact specifications, ensuring a consistent fit and reliable operation within the engine block. This set is a solid option for those rebuilding or significantly upgrading their Cummins 5.9L engine, aiming for improved power output and longevity.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Proper ring gap setting and cylinder wall preparation are crucial for optimal performance and engine life. This set is intended for performance-oriented diesel builds where reliability and power are key considerations.
