CP Piston BRS Chevy LS7 4.135 Bore 4.000 Stroke 6.125 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS Series pistons, specifically made for Chevy LS7 engines. You get pistons with a 4.135 inch bore, designed for a 4.000 inch stroke, and intended to be used with 6.125 inch connecting rods. These are a made-to-order item, meaning they are built specifically for your order and cannot be canceled once placed.

CP Pistons is known for making well-built internal engine components. These BRS Series pistons are forged from high-strength aluminum, which is a strong material that can handle the high pressures and temperatures found in performance engines. The forged construction means they are more resistant to deformation and cracking compared to cast pistons, making them a solid choice for builds that demand reliability under stress. The specific dimensions – 4.135" bore, 4.000" stroke, and 6.125" rod length – are critical for achieving the correct compression ratio and displacement for your LS7 build. This set is designed to fit right into your LS7 engine build, assuming all other components are within spec.

Because these pistons are made to order, please allow for production time. They are not CARB approved and cannot be shipped to California. If you're building a high-performance LS7 engine and need reliable, strong pistons, this set from CP Pistons is a popular option.
