CP Piston Diesel Set Chevy / GMC Duramax 6.6L - Bore (4.075in) - CH (1.744)

This is a set of CP Pistons DHR7030-8 diesel pistons, specifically made for Chevy and GMC trucks equipped with the 6.6L Duramax engine. If you're rebuilding the heart of your diesel truck, especially if you plan on pushing its limits or are dealing with significant wear, a new set of pistons is a critical component. These pistons are designed to handle the high pressures and temperatures inherent in diesel operation, ensuring reliable performance under demanding conditions.

CP Pistons is known for its well-built engine components, and this diesel piston set is no exception. They feature a 4.075-inch bore size, which is the standard bore for many Duramax applications, and a 1.744-inch compression height (CH). This specific compression height is important for ensuring correct piston-to-head clearance and valve timing when paired with the right connecting rods and crankshaft. The material and construction are geared towards durability and consistent performance, which is essential for a diesel engine that often works hard.

When undertaking a diesel engine rebuild, especially for a Duramax, using high-quality internal components like these pistons can make a significant difference in the longevity and power output of your engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures, as correct installation is key to achieving the intended performance and durability.
