CP Piston BRS SBC 4.135 Bore 3.875 Stroke 6.000 Rod 13.75 To 1 Set Of 8 (MTO Non-Cancel)

These CP Pistons are forged from high-strength aluminum alloy, specifically designed for high-performance Small Block Chevy (SBC) engines. The 4.135-inch bore and 3.875-inch stroke, paired with a 6.000-inch rod length, are engineered to achieve a 13.75:1 compression ratio, making them suitable for naturally aspirated or forced induction applications where maximum power is the goal. This set includes eight pistons, ready for your engine build.

The BRS series pistons feature a unique skirt design and advanced forging process that contributes to their well-built nature and durability under extreme stress. The material choice and construction help manage heat effectively, which is crucial for maintaining performance and longevity in demanding engine builds. Each piston is precision-machined to exact tolerances, ensuring a proper fit and optimal sealing within the cylinder bore. This attention to detail is what you expect from CP Pistons, a popular name in racing circles.

Because these pistons are custom-made to order (MTO), they are non-cancelable and non-returnable once production begins. Please verify your engine specifications and requirements carefully before ordering. Note that this product is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional for installation and tuning recommendations.
