CP Piston Bullet Race Series Chevy LS74.135 Bore 4.000 Stroke 6.077 Rod Set Of 8

This is a set of CP Pistons Bullet Race Series pistons, specifically made for Chevy LS7 engines. These pistons feature a 4.135-inch bore, a 4.000-inch stroke, and are designed to work with a 6.077-inch connecting rod. This set includes eight pistons, which is what you need for a V8 engine like the LS7.

CP Pistons is known for making well-built internal engine components, and this Bullet Race Series is designed for high-performance applications. They are forged from strong aluminum alloy, which gives them the durability needed to handle the increased cylinder pressures and temperatures found in performance builds. The 4.135-inch bore size is a common upgrade for LS7 engines looking to increase displacement. The specific dimensions for stroke and rod length are critical for proper engine assembly and performance tuning, ensuring the piston moves correctly within the cylinder bore.

When rebuilding or significantly upgrading your LS7 engine, choosing the right pistons is crucial. These CP Pistons are a solid option for those looking to build a powerful naturally aspirated or forced induction engine. Remember that these pistons are 0.010 inches larger than the stock bore size, so your engine block will need to be machined to this specific size. It's always recommended to consult with your engine builder or machinist to ensure all clearances and specifications are met for your particular build. Please note that these pistons are not CARB approved and cannot be shipped to California.
