CP Piston BRS BBC 25.4CC Dome 4.310 Bore 4.250 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight forged pistons from CP Pistons, specifically designed for big block Chevrolet (BBC) engines. These pistons feature a 25.4cc dome volume, a 4.310-inch bore, and are intended for use with a 4.250-inch stroke crankshaft and 6.385-inch connecting rods. CP Pistons are known for their robust construction and precision manufacturing, making them a popular choice for high-performance engine builds where durability and reliability under extreme conditions are paramount.

The BRS series pistons are crafted from high-strength aluminum alloy, chosen for its excellent strength-to-weight ratio. This material choice helps reduce reciprocating mass, which can lead to improved engine response and higher RPM capabilities. The dome design is engineered to achieve a specific compression ratio when paired with the correct cylinder head volume and deck height, crucial for optimizing power output and efficiency in a performance application. Each piston is meticulously machined to exact tolerances, ensuring a perfect fit within the cylinder bore and proper sealing with the piston rings. The included piston skirts are designed to minimize friction and wear against the cylinder wall, contributing to longer engine life.

This set is a Make-To-Order (MTO) item and cannot be canceled once the order is placed, so please confirm your engine specifications carefully before purchasing. These pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and a well-built engine that can handle significant stress, this set of CP Pistons offers a solid foundation.
