CP Piston BRS BBC 4.605 Bore 4.250 Stroke 6.535 Rod Set Of 8 (MTO Non-Cancel)

Forged from 2618-T61 aluminum, these CP Pistons are built for serious performance applications. The 4.605-inch bore size is specifically chosen for Big Block Chevrolet (BBC) engines, and when paired with the 4.250-inch stroke and 6.535-inch rod length, they create a robust rotating assembly ready for high-output builds.

CP Pistons are well-known for their advanced forging process, which results in a strong yet lightweight piston. This particular set utilizes the BRS (Bullet Racing Series) design, featuring a deep valve relief to accommodate high-lift camshafts and large valve sizes commonly found in performance BBC builds. The piston skirts are coated to reduce friction and wear, helping to ensure longevity even under demanding conditions. Each piston is precision-machined to exact tolerances, ensuring a perfect fit and optimal performance within the cylinder.

This set includes eight pistons, designed as a direct replacement for your BBC engine's original components, though it's important to note these are made to order and cannot be canceled once placed. Due to emissions regulations, this part is not CARB approved and cannot be shipped to California. For optimal results and longevity, it's recommended to consult with a professional engine builder for installation and tuning.
