CP Pistons Set Chrysler Cummins 6.7L 4.125 Bore 4.882 Stroke 7.559 Rod -51.7cc Dome - Set of 6

This is a set of six forged pistons from CP Pistons, specifically made for the Chrysler Cummins 6.7L engine. These pistons are designed to handle the demands of a high-performance or heavily modified diesel engine, offering a significant upgrade over stock components. With a 4.125 inch bore and a 4.882 inch stroke, they are built for engines that require increased displacement and power output. The 7.559 inch rod length is also a key dimension for this specific engine build.

CP Pistons are well-known for their robust construction and attention to detail. These particular pistons feature a -51.7cc dome volume, which is crucial for achieving the desired compression ratio and combustion characteristics when paired with the right cylinder head and camshaft. The forged aluminum construction means they are incredibly strong and durable, able to withstand higher cylinder pressures and temperatures that come with increased boost or aggressive tuning. This makes them a solid choice for anyone rebuilding or significantly upgrading their Cummins engine for towing, racing, or heavy-duty work.

When installing these pistons, it's important to ensure your engine block is properly machined to the 4.125 inch bore size and that all other rotating assembly components, including the crankshaft and connecting rods, are balanced. Proper piston ring installation and cylinder wall preparation are also critical for optimal performance and longevity. This set includes all six pistons needed for a complete engine rebuild, providing a matched set for consistent performance across all cylinders.
