CP Piston BRS SBC 4.155 Bore 3.625 Stroke 6.000 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS pistons designed for Small Block Chevy (SBC) engines. They feature a 4.155 inch bore and a 3.625 inch stroke, intended to be used with a 6.000 inch connecting rod. These pistons are built for performance applications where strength and reliability are paramount. CP Pistons is known for producing well-built internal engine components for demanding builds.

The BRS series pistons are forged from high-strength aluminum alloy, which provides a solid foundation for high horsepower and high-RPM operation. This forging process creates a denser, more uniform grain structure compared to cast pistons, making them significantly more resistant to detonation and fatigue. The specific design of these pistons takes into account factors like piston-to-wall clearance and ring land durability to ensure longevity under stress. The 4.155 inch bore size is common for many popular SBC stroker combinations, and the 6.000 inch rod length offers a good balance for stroke and rod ratio, contributing to improved engine efficiency and reduced friction.

This set is a made-to-order (MTO) item and cannot be canceled once the order is placed. Please ensure this is the correct piston specification for your engine build before purchasing. Due to their specialized nature and performance focus, these pistons are not CARB approved and cannot be shipped to California. Consult your engine builder or a trusted performance shop to confirm compatibility with your specific engine components and build goals.
