CP Piston BRS SBC 4.150 Bore 3.875 Stroke 6.000 Rod Set Of 8 (MTO Non-Cancel)

These CP Pistons are built with a 4.150 inch bore and a 3.875 inch stroke, designed for a 6.000 inch rod. This specific configuration is crucial for achieving the desired compression ratio and displacement in a Small Block Chevy (SBC) engine build. The BRS series pistons are forged from high-strength aluminum alloy, a material chosen for its excellent strength-to-weight ratio, which is vital for high-performance applications where reducing reciprocating mass is key to engine responsiveness and durability under stress. Each piston in this set of eight is precision-machined to tight tolerances, ensuring consistent performance and reliability across all cylinders.

The BRS series features a specific skirt design and wall thickness that contribute to improved piston stability and reduced friction within the cylinder bore. This design helps manage heat effectively and minimizes the risk of piston slap, even under demanding operating conditions. The forged construction means these pistons are significantly stronger than cast pistons, making them well-suited for boosted applications or high-RPM engines where extreme cylinder pressures are common. They are designed to work with a 6.000 inch connecting rod, a common length for many performance SBC builds, allowing for optimal rod angle and reduced side loading.

Because these pistons are made to order (MTO), they are not cancelable once production begins. This ensures you receive a fresh set built specifically for your order. While these pistons are built for high performance, please note they are not CARB approved and cannot be shipped to California. For optimal installation and performance, always refer to the manufacturer's detailed specifications and recommended assembly procedures.
