CP Piston Set for Chrysler Cummins 5.9L - Bore (4.02) - Stroke (4.724) - Rod (7.559) - (Set of 6)

CP Pistons is well-known for building high-performance engine components, and this set of forged pistons for the Chrysler Cummins 5.9L is a prime example of their work. If you're rebuilding the heart of your truck and need a robust piston solution, these are built to handle the demands of a performance diesel engine. They are designed with specific dimensions: a 4.02-inch bore, a 4.724-inch stroke, and a 7.559-inch rod length, ensuring they integrate properly into your engine build.

Forged pistons like these are a significant upgrade over cast pistons. They start as a solid block of aluminum alloy that's heated and then hammered into shape under immense pressure. This process creates a much denser, stronger grain structure throughout the piston, making them far more resistant to the extreme heat and pressure found in high-performance diesel engines. This improved strength means they can withstand higher boost levels and more aggressive tuning without risking failure. This set includes six pistons, enough for a complete engine rebuild.

When undertaking a diesel engine rebuild, especially one involving performance upgrades, using well-built internal components is crucial for long-term reliability and power. These CP Pistons are a solid option for anyone looking to build a strong, dependable engine for their Cummins-powered vehicle. Please note that these pistons are not CARB approved and cannot be shipped to California.
