CP Piston BRS SBC 4.145 Bore Stroke 3.875 6.00 Rod 1.062 Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Small Block Chevy (SBC) engine, getting the right pistons is crucial for reliability and power. This set from CP Pistons is designed for serious builds, featuring a 4.145-inch bore and a 3.875-inch stroke, paired with a 6.00-inch rod length. These dimensions are key for achieving specific displacement and compression ratios tailored to your engine's intended use, whether it's for racing, heavy towing, or a street/strip application.

CP Pistons are well-known in the performance engine world for their robust construction and attention to detail. These pistons are forged, meaning they start from a solid block of aluminum alloy that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast alternatives, making them ideal for engines that will see high cylinder pressures and temperatures. The specific BRS (Big Rod Series) design indicates they are optimized for use with longer connecting rods, which can improve piston side-load characteristics and reduce friction at higher RPMs. The 1.062-inch pin diameter is standard for many performance applications, ensuring compatibility with a wide range of aftermarket connecting rods.

This is a made-to-order (MTO) set, meaning it's built specifically for your order and cannot be canceled once placed. This ensures you're getting a fresh, precisely manufactured set. Because these are custom-built, please allow for production time. They are not CARB approved and cannot be shipped to California. Ensure you check all local emissions regulations before ordering.
